CONTRAINDICATIONS / PRECAUTIONS
Acute bronchospasm, asthma, nasal polyps, NSAID hypersensitivity, salicylate hypersensitivity, urticaria
Indomethacin is contraindicated in patients with salicylate hypersensitivity or NSAID hypersensitivity who have experienced asthma, urticaria, or other allergic reactions after taking aspirin or other NSAIDs. Severe, rarely fatal, anaphylactoid reactions to indomethacin have been reported in such patients. Indomethacin should not be used in asthma patients with aspirin-sensitive asthma or the aspirin triad because of the approximate 5% cross-sensitivity that occurs between aspirin and NSAIDs. The triad typically occurs in asthmatic patients who experience rhinitis with or without nasal polyps, or who experience severe, potentially fatal, acute bronchospasm after taking aspirin or other NSAIDs. The use of NSAIDs, including indomethacin, may cause serious and potentially fatal skin reactions including exfoliative dermatitis, Stevens-Johnson syndrome, and toxic epidermal necrolysis. Patients should be instructed to discontinue the medication and contact their health care provider if erythema, rash, blisters, or related skin reactions develop.
Aortic coarctation, bleeding, congenital heart disease, infection, intracranial bleeding, necrotizing enterocolitis, neonates
Although indomethacin for injection is indicated for use in premature newborns to close a PDA, use is contraindicated in neonates with specific co-morbid conditions. Do not use indomethacin IV in neonates with proven or suspected untreated infection; neonates who are bleeding, especially neonates with intracranial bleeding or neonates with gastrointestinal bleeding; neonates with coagulation disorders or low platelets; neonates with necrotizing enterocolitis; neonates with significant renal dysfunction; or in neonates with PDA-essential congenital heart disease (e.g., pulmonary atresia, severe tetralogy of Fallot, severe aortic coarctation). Use other forms of indomethacin with caution, if at all, in other patient populations with the same or similar health conditions as those listed here.
Alcoholism, anticoagulant therapy, chemotherapy, corticosteroid therapy, GI bleeding, GI disease, GI perforation, hemorrhoids, peptic ulcer disease, tobacco smoking, ulcerative colitis
Nonsteroidal anti-inflammatory drugs (NSAIDs) are well known to cause gastrointestinal injury. Indomethacin suppositories are contraindicated in patients with a history of proctitis or recent rectal bleeding. Rectally administered indomethacin should be used with caution in patients with hemorrhoids, anal, or rectal inflammation. The use of intravenous indomethacin is contraindicated in neonates with gastrointestinal bleeding. Chronic use of indomethacin can result in gastritis, ulceration with or without GI perforation, and/or GI bleeds, which can occur at any time, often without preceding symptoms. Therefore, use all forms of indomethacin with caution in patients with a history of or active GI disease including peptic ulcer disease, ulcerative colitis, or GI bleeding. Patients with a prior history of peptic ulcer disease or GI bleeding who use NSAIDs have a greater than 10-fold increased risk for developing a GI bleed compared to patients with neither of these risk factors. It is recommended not to initiate therapy with maximum doses in these patients due to the likely increase frequency of adverse reactions. All patients receiving prolonged treatment should be routinely monitored for potential GI ulceration and bleeding. Patients at increased risk for NSAID-induced GI bleeding include those receiving concurrent myelosuppressive chemotherapy, corticosteroid therapy, or anticoagulant therapy, tobacco smoking patients, the elderly, and patients with alcoholism. Indomethacin may aggravate active conditions or reactivate latent conditions. Consider alternative therapies to NSAIDs for high risk patients.
Bone marrow suppression, coagulopathy, hemophilia, immunosuppression, neutropenia, surgery, thrombocytopenia
Indomethacin, like other NSAIDs, inhibits platelet aggregation and has been shown to prolong bleeding time in some patients. Unlike aspirin, the effect on platelet function is quantitatively less, of shorter duration, and reversible. Patients receiving indomethacin who may be adversely affected by alterations in platelet function, such as those with coagulation disorders (e.g., coagulopathy, hemophilia) or patients receiving anticoagulants, should be carefully monitored. The use of intravenous indomethacin is contraindicated in neonates with coagulopathy or thrombocytopenia. Indomethacin should also be used with caution in patients undergoing surgery when a high degree of hemostasis is required. NSAIDs should also be used with caution in patients with immunosuppression or neutropenia as NSAID use may mask the signs of infection such as fever or pain in patients with bone marrow suppression.
Anemia
Anemia is sometimes seen in patients receiving NSAIDs, including indomethacin. This may be due to fluid retention, occult or gross GI blood loss, or an incompletely described effect upon erythropoiesis. Patients on long-term treatment with NSAIDs, including indomethacin, should have their hemoglobin or hematocrit checked if they exhibit any signs or symptoms of anemia.
Visual disturbance
Corneal deposits and retinal disturbances, including those of the macula, have been observed in some patients who had received prolonged therapy with indomethacin. Since these changes may be asymptomatic, ophthalmologic examination at periodic intervals is desirable in patients receiving prolonged therapy. Blurred and/or diminished vision has been reported with the use of other systemic NSAIDs. Patients experiencing eye complaints or visual disturbance should have an ophthalmologic examination. It is advisable to discontinue therapy if such changes are observed.
Hepatic disease, jaundice
Borderline elevations of one or more liver function tests (LFTs) may occur in up to 15% of patients taking NSAIDs, including indomethacin. These laboratory abnormalities may progress, may remain unchanged, or may be transient with continuing therapy. Notable elevations of ALT or AST of approximately 3 or more times the upper limit of normal (ULN) have been reported in approximately 1% of patients in clinical trials with NSAIDs. In addition, rare cases of severe hepatic reactions, including jaundice and fatal fulminant hepatitis, liver necrosis and hepatic failure, some of them with fatal outcomes have been reported. A patient with signs and symptoms suggesting liver dysfunction, or in whom abnormal LFTs have occurred, should be evaluated for evidence of the development of a more severe hepatic reaction while on therapy with indomethacin. If clinical signs and symptoms consistent with hepatic disease develop, or if systemic manifestations occur (e.g., eosinophilia, rash, etc.), discontinue indomethacin immediately.
Dental disease, dental work
Use of indomethacin may cause increased bleeding in patients with dental disease. Patients should inform their dentist they are taking indomethacin prior to any dental work due to a potential increased risk of bleeding. Patients should be instructed on proper oral hygiene.
Dehydration, hyperkalemia, renal disease, renal failure, renal impairment
Due to the role of prostaglandins in renal function and hemodynamics, patients with renal disease should be closely observed during therapy with indomethacin due to an increased risk for adverse reactions during treatment. Due to a lack of data, treatment with indomethacin is not recommended in patients with advanced renal disease; if therapy is absolutely necessary, monitor the patient closely. The use of intravenous indomethacin is contraindicated in newborns with significant renal impairment or renal failure. Use caution when initiating treatment with indomethacin in patients with considerable dehydration, due to the risk for reduced renal perfusion. Long-term administration of NSAIDs has resulted in renal papillary necrosis and other renal injury. Renal toxicity has also been seen in patients in whom renal prostaglandins have a compensatory role in the maintenance of renal perfusion. In these patients, administration of a NSAID may cause a dose-dependent reduction in prostaglandin formation and, secondarily, in renal blood flow, which may precipitate over renal decompensation. Patients at greatest risk of this reaction are those with renal impairment, cardiac failure, liver dysfunction, patients with hypovolemia or dehydration, the elderly, and those taking diuretics, ACE inhibitors, or nephrotoxic drugs. Discontinuation of NSAID therapy is usually followed by recovery to the pretreatment state. Increases in serum potassium concentration, including hyperkalemia, have been reported with use of indomethacin, even in some patients without renal impairment. In patients with normal renal function, these effects have been attributed to a hyporeninemic-hypoaldosteronism state.
Acute myocardial infarction, angina, cardiac arrhythmias, cardiac disease, cardiomyopathy, cerebrovascular disease, coronary artery disease, heart failure, hypertension, myocardial infarction, peripheral vascular disease, stroke, thromboembolism
Indomethacin should be used with caution in patients with hypertension or cardiac disease. All nonsteroidal anti-inflammatory drugs (NSAIDs) may cause fluid retention, may cause new or worsening hypertension, may exacerbate congestive heart failure and may cause an increased risk of serious cardiovascular thromboembolism, myocardial infarction, and stroke, which can be fatal. In a study of patients with severe heart failure and hyponatremia, indomethacin was associated with significant deterioration of circulatory hemodynamics, presumably due to inhibition of prostaglandin dependent compensatory mechanisms. The FDA has warned that the risk of myocardial infarction or stroke can occur as early as the first weeks of using a NSAID, and risk may increase with higher doses and longer duration of use. Data demonstrate that patients treated with NSAIDs were more likely to die in the first year following a myocardial infarction compared to those not treated with NSAIDs. NSAIDs may increase the risk of a cardiovascular thrombotic event in patients with or without underlying heart disease or risk factors for heart disease. Patients with known heart disease or risk factors appear to have a greater likelihood of an event following NSAID use, likely due to a higher baseline risk. Current evidence is insufficient to determine if the risk of an event is higher or lower for any particular NSAID compared to other NSAIDs. There is an increased risk of heart failure with NSAID use. Caution is recommended when administering indomethacin to patients with cardiomyopathy, cardiac arrhythmias, significant coronary artery disease (including angina, or history of myocardial infarction), peripheral vascular disease, cerebrovascular disease (e.g., stroke, transient ischemic attack), pre-existing renal disease, or edema. In addition, clinical practice guidelines state NSAIDs should not be administered to patients presenting with and hospitalized for ST-elevation acute myocardial infarction (STEMI) due to increased risk of mortality, reinfarction, hypertension, heart failure, and myocardial rupture associated with their use. Monitor blood pressure (BP) closely during the initiation of indomethacin treatment and throughout the course of therapy. Patients taking ACE inhibitors, thiazides or loop diuretics or beta-adrenoceptor blocking agents may have impaired response to these therapies when taking NSAIDs. Use the lowest effective dose for the shortest duration possible to minimize the potential risk for an adverse cardiovascular event. Inform patients to seek immediate medical attention if they experience any signs or symptoms of a cardiovascular thrombotic event.
Coronary artery bypass graft surgery (CABG)
Indomethacin is contraindicated for the treatment of peri-operative pain in the setting of coronary artery bypass graft surgery (CABG). An increased incidence of myocardial infarction and stroke was found through analysis of data regarding the use of a COX-2 selective NSAID for the treatment of pain in the first 10 to 14 days after CABG surgery.
Depression, driving or operating machinery, headache, Parkinson's disease, seizure disorder
Indomethacin may cause central nervous system (CNS) side effects and should be used with caution in patients with a seizure disorder, Parkinson's disease, or depression or other psychiatric disturbance. Indomethacin may aggravate these conditions. Discontinue the drug if severe CNS adverse reactions develop. Indomethacin may cause drowsiness; therefore, patients should be cautioned against driving or operating machinery or engaging in other activities that require mental alertness and coordination until they know how the drug affects them. Indomethacin may also cause headache; headache which persists despite dosage reduction requires cessation of therapy.
Pregnancy
Avoid indomethacin use during the third trimester of pregnancy (starting at 30 weeks of gestation) due to the risk of premature closure of the fetal ductus arteriosus and persistent pulmonary hypertension in the neonate. If NSAID treatment is deemed necessary between 20 to 30 weeks of pregnancy, limit use to the lowest effective dose and shortest duration possible. Consider ultrasound monitoring of amniotic fluid if NSAID treatment extends beyond 48 hours. Discontinue the NSAID if oligohydramnios occurs and follow up according to clinical practice. Use of NSAIDs around 20 weeks gestation or later in pregnancy may cause fetal renal dysfunction leading to oligohydramnios, and in some cases, neonatal renal impairment. These adverse outcomes are seen, on average, after days to weeks of treatment, although oligohydramnios has been infrequently reported as soon as 48 hours after NSAID initiation. Oligohydramnios is often, but not always, reversible with treatment discontinuation. Complications of prolonged oligohydramnios may include limb contractures and delayed lung maturation. In some postmarketing cases of impaired neonatal renal function, invasive procedures such as exchange transfusion or dialysis were required. Observational data regarding embryofetal risks of NSAID use during the first trimester is inconclusive. There are no adequate and well-controlled studies of indomethacin in pregnant women.
Breast-feeding
Indomethacin is secreted into human breast milk and is not recommended in mothers who are breast-feeding. Of note, intravenous indomethacin is used therapeutically short-term in neonates, including premature neonates, at doses significantly higher than those that would be delivered via breast milk. However, other NSAIDs and analgesics may have more data regarding use during lactation. Alternative analgesic and antiinflammatory drugs considered to be usually compatible with breast-feeding include acetaminophen, ibuprofen, naproxen, and piroxicam. Injectable indomethacin is only indicated for use in neonates and should not be used in breast-feeding mothers. Consider the benefits of breast-feeding, the risk of potential infant drug exposure, and the risk of an untreated or inadequately treated condition. If a breast-feeding infant experiences an adverse effect related to a maternally ingested drug, healthcare providers are encouraged to report the adverse effect to the FDA.
Geriatric
Geriatric patients are at greater risk for serious gastrointestinal (GI) events (e.g., bleeding, ulceration, perforation) from NSAIDs such as indomethacin. NSAIDs are well known to cause gastrointestinal injury. Chronic use of indomethacin can result in gastritis, ulceration with or without GI perforation, and GI bleeds, which can occur at any time, often without preceding symptoms. Most spontaneous reports of fatal GI events are in elderly or debilitated patients. All patients receiving prolonged treatment should be routinely monitored for potential GI ulceration and bleeding. Consider alternative therapies to NSAIDs for high-risk patients. Additionally, indomethacin may induce confusion and rarely, psychosis. Clinicians should remain alert to the possibility of such CNS adverse effects in the elderly. Indomethacin is substantially excreted by the kidney and the risk of toxic reactions to this drug may be greater in patients with impaired renal function, including elderly patients who are more likely to have decreased renal function. Care should be taken in dose selection, and it may be useful to monitor renal function.[45886] [36583] According to the Beers Criteria, indomethacin is a potentially inappropriate medication (PIM) in geriatric patients. Avoid the use of indomethacin in the elderly due to an increased risk of gastrointestinal bleeding/peptic ulcer disease and acute kidney injury in older adults vs. other NSAIDs. Indomethacin is associated with the most adverse effects of all of the NSAIDs and is more likely than other NSAIDs to have adverse CNS effects.[63923] The federal Omnibus Budget Reconciliation Act (OBRA) regulates medication use in residents of long-term care facilities (LTCFs); NSAIDs should be reserved for symptoms and inflammatory conditions for which lower risk analgesics (e.g., acetaminophen) have either failed or are not clinically indicated. NSAIDs, and particularly indomethacin, may cause GI bleeding in patients with a prior history of, or with increased risk for, GI bleeding, or may cause or worsen renal failure, increase blood pressure, or exacerbate heart failure. Prolonged use of indomethacin should be avoided because of CNS side effects, such as headache, dizziness, somnolence, and confusion.[60742]
Children, infants
Safety and effectiveness of indomethacin in children and adolescents 14 years of age and younger has not been established. Infants should not receive indomethacin other than use in newborns to facilitate closure of patent ductus arteriosus (PDA). Indomethacin should not be prescribed for pediatric patients 2 to 14 years of age unless toxicity or lack of efficacy associated with other drugs warrants the risk. In experience with more than 900 pediatric patients treated with indomethacin, from published literature or the manufacturer, reported side effects in pediatric patients were comparable to those reported in adults. However, there have been cases of hepatotoxicity reported in pediatric patients with juvenile rheumatoid arthritis, including fatalities. If indomethacin treatment is instituted, use the lowest effective dose for the shortest possible duration. Closely monitor pediatric patients, including periodic assessment of liver function. Indomethacin should be discontinued if elevated hepatic enzymes occur and persist or worsen or if signs or symptoms of hepatic disease, such as jaundice, develop.
Intramuscular injections
Indomethacin inhibits platelet aggregation and may prolong bleeding time. Intramuscular injections should be administered cautiously as they may cause bleeding, bruising, or hematomas.
DRUG INTERACTIONS
Abciximab: (Moderate) Monitor for signs and symptoms of bleeding during concomitant platelet inhibitor and chronic nonsteroidal antiinflammatory drug (NSAID) use. Concomitant use increases the risk of bleeding.
Acebutolol: (Moderate) Monitor blood pressure during concomitant beta-blocker and nonsteroidal anti-inflammatory drug (NSAID) use. The antihypertensive effect of beta-blockers may be diminished by NSAIDs.
Acetaminophen; Aspirin, ASA; Caffeine: (Major) The concurrent use of salicylates and indomethacin is not recommended. Combined use does not produce any greater therapeutic effect than indomethacin monotherapy. Also, a significantly greater incidence of gastrointestinal adverse effects with concurrent use has been observed. Because NSAIDs can cause GI bleeding, inhibit platelet aggregation, and prolong bleeding time, additive effects may be seen in patients receiving platelet inhibitors (e.g., aspirin), anticoagulants, or thrombolytic agents.

Because NSAIDs can cause GI bleeding, inhibit platelet aggregation, and prolong bleeding time, additive effects may be seen in patients receiving platelet inhibitors (e.g., aspirin), anticoagulants, or thrombolytic agents.
Acetaminophen; Aspirin; Diphenhydramine: (Major) The concurrent use of salicylates and indomethacin is not recommended. Combined use does not produce any greater therapeutic effect than indomethacin monotherapy. Also, a significantly greater incidence of gastrointestinal adverse effects with concurrent use has been observed. Because NSAIDs can cause GI bleeding, inhibit platelet aggregation, and prolong bleeding time, additive effects may be seen in patients receiving platelet inhibitors (e.g., aspirin), anticoagulants, or thrombolytic agents.
Acetohexamide: (Moderate) NSAIDs may enhance hypoglycemia in diabetic patients via inhibition of prostaglandin synthesis, which indirectly increases insulin secretion. If NSAIDs are administered or discontinued in patients receiving oral antidiabetic agents, patients should be monitored for hypoglycemia or loss of blood glucose control. No clinically significant interaction between sulindac at daily doses of 400 mg and oral hypoglycemic agents has been observed. Sulindac, its sulfide metabolite, and sulfonylureas are highly bound to protein. Sulindac could displace the sulfonylureas, altering hypoglycemic activity. Careful patient monitoring is recommended to ensure that no change in their diabetes medicine dosage is required. A sulfonylurea dose adjustment may be needed, especially if sulindac doses greater than 400 mg daily are used or if the drug combination is used in patients with renal impairment or other metabolic defects that might increase sulindac blood concentrations.
Acyclovir: (Moderate) Monitor patients for signs of worsening renal function during coadministration of acyclovir and nonsteroidal antiinflammatory drugs. Coadministration may increase the risk for drug-induced nephrotoxicity.
Adefovir: (Moderate) Chronic coadministration of adefovir with nephrotoxic drugs, such as nonsteroidal antiinflammatory drugs may increase the risk of developing nephrotoxicity even in patients who have normal renal function. The use of adefovir with NSAIDs may be done cautiously. As stated in the current adefovir prescribing information, 'Ibuprofen (800 mg PO three times daily), when given concomitantly with adefovir dipivoxil, increased the adefovir Cmax by 33% and AUC by 23%, as well as urinary recovery. The increase appears to be due to higher oral bioavailability, not a reduction in renal clearance of adefovir.' In an in vitro investigation, the antiviral effect of adefovir was unaltered and the renal proximal tubule accumulation of adefovir was inhibited by the presence of a NSAID. Adefovir is efficiently transported by the human renal organic anion transporter 1, and the presence of this transporter appears to mediate the accumulation of the drug in renal proximal tubules. The in vitro study suggests that the use of a NSAID with adefovir may potentially reduce the nephrotoxic potential of adefovir. Of course, NSAIDs are associated with nephrotoxicity of their own; therefore, further data on the interaction between NSAIDs and adefovir in humans are needed.
Aldesleukin, IL-2: (Major) Aldesleukin, IL-2 may cause nephrotoxicity. Concurrent administration of drugs possessing nephrotoxic effects, such as nonsteroidal antiinflammatory agents (NSAIDs), with Aldesleukin, IL-2 may increase the risk of kidney dysfunction. In addition, reduced kidney function secondary to Aldesleukin, IL-2 treatment may delay elimination of concomitant medications and increase the risk of adverse events from those drugs.
Alendronate: (Minor) Monitor for gastrointestinal adverse events during concurrent use of alendronate and nonsteroidal antiinflammatory drugs. Both medications have been associated with gastrointestinal irritation although data suggest concomitant use introduces little additional risk for adverse effects for most patients.
Alendronate; Cholecalciferol: (Minor) Monitor for gastrointestinal adverse events during concurrent use of alendronate and nonsteroidal antiinflammatory drugs. Both medications have been associated with gastrointestinal irritation although data suggest concomitant use introduces little additional risk for adverse effects for most patients.
Aliskiren: (Moderate) NSAIDs may attenuate the antihypertensive effects of aliskiren by inhibiting the synthesis of vasodilatory prostaglandins. In patients who are elderly, volume-depleted (including those on diuretic therapy), or with compromised renal function who are being treated with NSAIDs, the coadministration of aliskiren may result in a further deterioration of renal function, including acute renal failure. These effects are usually reversible. Therefore, blood pressure and renal function should be monitored closely when an NSAID is administered to a patient taking aliskiren.
Aliskiren; Amlodipine: (Moderate) NSAIDs may attenuate the antihypertensive effects of aliskiren by inhibiting the synthesis of vasodilatory prostaglandins. In patients who are elderly, volume-depleted (including those on diuretic therapy), or with compromised renal function who are being treated with NSAIDs, the coadministration of aliskiren may result in a further deterioration of renal function, including acute renal failure. These effects are usually reversible. Therefore, blood pressure and renal function should be monitored closely when an NSAID is administered to a patient taking aliskiren.
Aliskiren; Amlodipine; Hydrochlorothiazide, HCTZ: (Moderate) NSAIDs may attenuate the antihypertensive effects of aliskiren by inhibiting the synthesis of vasodilatory prostaglandins. In patients who are elderly, volume-depleted (including those on diuretic therapy), or with compromised renal function who are being treated with NSAIDs, the coadministration of aliskiren may result in a further deterioration of renal function, including acute renal failure. These effects are usually reversible. Therefore, blood pressure and renal function should be monitored closely when an NSAID is administered to a patient taking aliskiren.
Aliskiren; Hydrochlorothiazide, HCTZ: (Moderate) NSAIDs may attenuate the antihypertensive effects of aliskiren by inhibiting the synthesis of vasodilatory prostaglandins. In patients who are elderly, volume-depleted (including those on diuretic therapy), or with compromised renal function who are being treated with NSAIDs, the coadministration of aliskiren may result in a further deterioration of renal function, including acute renal failure. These effects are usually reversible. Therefore, blood pressure and renal function should be monitored closely when an NSAID is administered to a patient taking aliskiren.
Aliskiren; Valsartan: (Moderate) Monitor blood pressure and renal function periodically during concomitant angiotensin II blocker and nonsteroidal anti-inflammatory drug (NSAID) use. The antihypertensive effect of angiotensin II blockers may be diminished by NSAIDs. In persons who are elderly, volume-depleted, or with compromised renal function, coadministration of angiotensin II blockers and NSAIDs may result in deterioration of renal function, including possible acute renal failure; these effects are usually reversible. (Moderate) NSAIDs may attenuate the antihypertensive effects of aliskiren by inhibiting the synthesis of vasodilatory prostaglandins. In patients who are elderly, volume-depleted (including those on diuretic therapy), or with compromised renal function who are being treated with NSAIDs, the coadministration of aliskiren may result in a further deterioration of renal function, including acute renal failure. These effects are usually reversible. Therefore, blood pressure and renal function should be monitored closely when an NSAID is administered to a patient taking aliskiren.
Alpha-blockers: (Moderate) If nonsteroidal anti-inflammatory drugs (NSAIDs) and an antihypertensive drug are concurrently used, carefully monitor the patient for signs and symptoms of renal insufficiency and blood pressure control. Doses of antihypertensive medications may require adjustment in patients receiving concurrent NSAIDs. NSAIDs, to varying degrees, have been associated with an elevation in blood pressure. This effect is most significant in patients receiving concurrent antihypertensive agents and long-term NSAID therapy. NSAIDs cause a dose-dependent reduction in prostaglandin formation, which may result in a reduction in renal blood flow leading to renal insufficiency and an increase in blood pressure that are often accompanied by peripheral edema and weight gain. Patients who rely upon renal prostaglandins to maintain renal perfusion may have acute renal blood flow reduction with NSAID usage. Elderly patients may be at increased risk of adverse effects from combined long-term NSAID therapy and antihypertensive agents, especially diuretics, due to age-related decreases in renal function and an increased risk of stroke and coronary artery disease.
Alteplase: (Moderate) NSAIDs can cause GI bleeding, inhibit platelet aggregation, prolong bleeding time; these pharmacodynamic effects may be increased when administered to patients receiving thrombolytic agents. Patients receiving these drugs concurrently should be monitored closely for bleeding.
Altretamine: (Major) Altretamine causes mild to moderate dose-related myelosuppression. Due to the thrombocytopenic effects of altretamine, an additive risk of bleeding may be seen in patients receiving concomitant NSAIDs. In addition, large doses of salicylates (>= 3-4 g/day) can cause hypoprothrombinemia, an additional risk factor for bleeding.
Ambenonium Chloride: (Moderate) NSAIDs may cause additive pharmacodynamic GI effects with cholinesterase inhibitors, leading to gastrointestinal intolerance. Patients receiving concurrent NSAIDs should be monitored closely for symptoms of active or occult gastrointestinal bleeding. While NSAIDs appear to suppress microglial activity, which in turn may slow inflammatory neurodegenerative processes important for the progression of Alzheimer's disease (AD), there are no clinical data at this time to suggest that NSAIDs alone or as combined therapy with AD agents result in synergistic effects in AD.
Amikacin: (Moderate) It is possible that additive nephrotoxicity may occur in patients who receive nonsteroidal antiinflammatory drugs (NSAIDs) concurrently with other nephrotoxic agents, such as amikacin.
Amiloride: (Moderate) Nonsteroidal anti-inflammatory drugs (NSAIDs) may reduce the natriuretic effect of diuretics in some patients. NSAIDS have been associated with an inhibition of prostaglandin synthesis, which may result in reduced renal blood flow leading to renal insufficiency and increases in blood pressure that are often accompanied by peripheral edema and weight gain. Patients taking diuretics and NSAIDS concurrently are at higher risk of developing renal insufficiency. If an NSAID and a diuretic are used concurrently, carefully monitor the patient for signs and symptoms of decreased renal function and diuretic efficacy.
Amiloride; Hydrochlorothiazide, HCTZ: (Moderate) Nonsteroidal anti-inflammatory drugs (NSAIDs) may reduce the natriuretic effect of diuretics in some patients. NSAIDS have been associated with an inhibition of prostaglandin synthesis, which may result in reduced renal blood flow leading to renal insufficiency and increases in blood pressure that are often accompanied by peripheral edema and weight gain. Patients taking diuretics and NSAIDS concurrently are at higher risk of developing renal insufficiency. If an NSAID and a diuretic are used concurrently, carefully monitor the patient for signs and symptoms of decreased renal function and diuretic efficacy.
Aminolevulinic Acid: (Moderate) Agents that inhibit prostaglandin synthesis such as nonsteroidal antiinflammatory drugs (NSAIDs), could decrease the efficacy of photosensitizing agents used in photodynamic therapy. Avoidance of NSAIDs before and during photodynamic therapy may be advisable.
Amiodarone: (Minor) Amiodarone inhibits CYP2C9. Caution is recommended when administering amiodarone with CYP2C9 substrates including indomethacin. The metabolism of indomethacin may be decreased.
Amlodipine; Benazepril: (Moderate) Monitor blood pressure and renal function periodically during concomitant angiotensin-converting enzyme (ACE) inhibitor and nonsteroidal anti-inflammatory drug (NSAID) use. The antihypertensive effect of ACE inhibitors may be diminished by NSAIDs. In persons who are elderly, volume-depleted, or with compromised renal function, coadministration of ACE inhibitors and NSAIDs may result in deterioration of renal function, including possible acute renal failure; these effects are usually reversible.
Amlodipine; Celecoxib: (Major) Avoid concomitant use of celecoxib with any other NSAID due to the risk of additive serious NSAID toxicities including but not limited to GI bleeding, GI perforation, or peptic ulcers.
Amlodipine; Olmesartan: (Moderate) Monitor blood pressure and renal function periodically during concomitant angiotensin II blocker and nonsteroidal anti-inflammatory drug (NSAID) use. The antihypertensive effect of angiotensin II blockers may be diminished by NSAIDs. In persons who are elderly, volume-depleted, or with compromised renal function, coadministration of angiotensin II blockers and NSAIDs may result in deterioration of renal function, including possible acute renal failure; these effects are usually reversible.
Amlodipine; Valsartan: (Moderate) Monitor blood pressure and renal function periodically during concomitant angiotensin II blocker and nonsteroidal anti-inflammatory drug (NSAID) use. The antihypertensive effect of angiotensin II blockers may be diminished by NSAIDs. In persons who are elderly, volume-depleted, or with compromised renal function, coadministration of angiotensin II blockers and NSAIDs may result in deterioration of renal function, including possible acute renal failure; these effects are usually reversible.
Amlodipine; Valsartan; Hydrochlorothiazide, HCTZ: (Moderate) Monitor blood pressure and renal function periodically during concomitant angiotensin II blocker and nonsteroidal anti-inflammatory drug (NSAID) use. The antihypertensive effect of angiotensin II blockers may be diminished by NSAIDs. In persons who are elderly, volume-depleted, or with compromised renal function, coadministration of angiotensin II blockers and NSAIDs may result in deterioration of renal function, including possible acute renal failure; these effects are usually reversible.
Amoxicillin: (Minor) Indomethacin may compete with penicillin for renal tubular secretion, increasing penicillin serum concentrations. This combination should be used with caution and patients monitored for increased side effects.
Amoxicillin; Clarithromycin; Omeprazole: (Minor) Indomethacin may compete with penicillin for renal tubular secretion, increasing penicillin serum concentrations. This combination should be used with caution and patients monitored for increased side effects.
Amoxicillin; Clavulanic Acid: (Minor) Indomethacin may compete with penicillin for renal tubular secretion, increasing penicillin serum concentrations. This combination should be used with caution and patients monitored for increased side effects.
Amphotericin B cholesteryl sulfate complex (ABCD): (Moderate) Concurrent use of amphotericin B and other nephrotoxic medications, including nonsteroidal antiinflammatory drugs (NSAIDs), may enhance the potential for drug-induced renal toxicity. Monitor renal function carefully during concurrent therapy. Amphotericin B dosage reduction may be necessary if renal impairment occurs.
Amphotericin B lipid complex (ABLC): (Moderate) Concurrent use of amphotericin B and other nephrotoxic medications, including nonsteroidal antiinflammatory drugs (NSAIDs), may enhance the potential for drug-induced renal toxicity. Monitor renal function carefully during concurrent therapy. Amphotericin B dosage reduction may be necessary if renal impairment occurs.
Amphotericin B liposomal (LAmB): (Moderate) Concurrent use of amphotericin B and other nephrotoxic medications, including nonsteroidal antiinflammatory drugs (NSAIDs), may enhance the potential for drug-induced renal toxicity. Monitor renal function carefully during concurrent therapy. Amphotericin B dosage reduction may be necessary if renal impairment occurs.
Amphotericin B: (Moderate) Concurrent use of amphotericin B and other nephrotoxic medications, including nonsteroidal antiinflammatory drugs (NSAIDs), may enhance the potential for drug-induced renal toxicity. Monitor renal function carefully during concurrent therapy. Amphotericin B dosage reduction may be necessary if renal impairment occurs.
Ampicillin: (Minor) Indomethacin may compete with penicillin for renal tubular secretion, increasing penicillin serum concentrations. This combination should be used with caution and patients monitored for increased side effects.
Ampicillin; Sulbactam: (Minor) Indomethacin may compete with penicillin for renal tubular secretion, increasing penicillin serum concentrations. This combination should be used with caution and patients monitored for increased side effects.
Anagrelide: (Moderate) Monitor for signs and symptoms of bleeding during concomitant platelet inhibitor and chronic nonsteroidal antiinflammatory drug (NSAID) use. Concomitant use increases the risk of bleeding.
Angiotensin II receptor antagonists: (Moderate) Monitor blood pressure and renal function periodically during concomitant angiotensin II blocker and nonsteroidal anti-inflammatory drug (NSAID) use. The antihypertensive effect of angiotensin II blockers may be diminished by NSAIDs. In persons who are elderly, volume-depleted, or with compromised renal function, coadministration of angiotensin II blockers and NSAIDs may result in deterioration of renal function, including possible acute renal failure; these effects are usually reversible.
Angiotensin-converting enzyme inhibitors: (Moderate) Monitor blood pressure and renal function periodically during concomitant angiotensin-converting enzyme (ACE) inhibitor and nonsteroidal anti-inflammatory drug (NSAID) use. The antihypertensive effect of ACE inhibitors may be diminished by NSAIDs. In persons who are elderly, volume-depleted, or with compromised renal function, coadministration of ACE inhibitors and NSAIDs may result in deterioration of renal function, including possible acute renal failure; these effects are usually reversible.
Antacids: (Moderate) Antacids may inhibit the oral absorption of indomethacin. Simultaneous administration should be avoided; separate dosing by at least 2 hours to limit an interaction.
Antithrombin III: (Moderate) An additive risk of bleeding may be seen in patients receiving anticoagulants in combination with other agents known to increase the risk of bleeding such as nonsteroidal antiinflammatory drugs (NSAIDs).

Aprepitant, Fosaprepitant: (Minor) Use caution if indomethacin and aprepitant are used concurrently and monitor for a possible decrease in the efficacy of indomethacin. After administration, fosaprepitant is rapidly converted to aprepitant and shares the same drug interactions. Indomethacin is a CYP2C9 substrate in vitro, and aprepitant is a CYP2C9 inducer. Administration of a CYP2C9 substrate, tolbutamide, on days 1, 4, 8, and 15 with a 3-day regimen of oral aprepitant (125 mg/80 mg/80 mg) decreased the tolbutamide AUC by 23% on day 4, 28% on day 8, and 15% on day 15. The AUC of tolbutamide was decreased by 8% on day 2, 16% on day 4, 15% on day 8, and 10% on day 15 when given prior to oral administration of aprepitant 40 mg on day 1, and on days 2, 4, 8, and 15. The effects of aprepitant on tolbutamide were not considered significant. When a 3-day regimen of aprepitant (125 mg/80 mg/80 mg) given to healthy patients on stabilized chronic warfarin therapy (another CYP2C9 substrate), a 34% decrease in S-warfarin trough concentrations was noted, accompanied by a 14% decrease in the INR at five days after completion of aprepitant.

Atropine; Benzoic Acid; Hyoscyamine; Methenamine; Methylene Blue; Phenyl Salicylate: (Major) The concurrent use of salicylates and indomethacin is not recommended. Combined use does not produce any greater therapeutic effect than indomethacin monotherapy. Also, a significantly greater incidence of gastrointestinal adverse effects with concurrent use has been observed. Because NSAIDs can cause GI bleeding, inhibit platelet aggregation, and prolong bleeding time, additive effects may be seen in patients receiving platelet inhibitors (e.g., aspirin), anticoagulants, or thrombolytic agents.
Atropine; Edrophonium: (Moderate) NSAIDs may cause additive pharmacodynamic GI effects with cholinesterase inhibitors, leading to gastrointestinal intolerance. Patients receiving concurrent NSAIDs should be monitored closely for symptoms of active or occult gastrointestinal bleeding. While NSAIDs appear to suppress microglial activity, which in turn may slow inflammatory neurodegenerative processes important for the progression of Alzheimer's disease (AD), there are no clinical data at this time to suggest that NSAIDs alone or as combined therapy with AD agents result in synergistic effects in AD.
Azathioprine: (Moderate) NSAIDs should be used with caution in patients receiving immunosuppressives as they may mask fever, pain, swelling and other signs and symptoms of an infection.
Azelastine; Fluticasone: (Moderate) Monitor for gastrointestinal toxicity during concurrent corticosteroid and nonsteroidal antiinflammatory drug (NSAID) use. Concomitant use increases the risk of GI bleeding. The Beers criteria recommends that this drug combination be avoided in older adults; if coadministration cannot be avoided, provide gastrointestinal protection.
Azilsartan: (Moderate) Monitor blood pressure and renal function periodically during concomitant angiotensin II blocker and nonsteroidal anti-inflammatory drug (NSAID) use. The antihypertensive effect of angiotensin II blockers may be diminished by NSAIDs. In persons who are elderly, volume-depleted, or with compromised renal function, coadministration of angiotensin II blockers and NSAIDs may result in deterioration of renal function, including possible acute renal failure; these effects are usually reversible.
Azilsartan; Chlorthalidone: (Moderate) Monitor blood pressure and renal function periodically during concomitant angiotensin II blocker and nonsteroidal anti-inflammatory drug (NSAID) use. The antihypertensive effect of angiotensin II blockers may be diminished by NSAIDs.

Benazepril; Hydrochlorothiazide, HCTZ: (Moderate) Monitor blood pressure and renal function periodically during concomitant angiotensin-converting enzyme (ACE) inhibitor and nonsteroidal anti-inflammatory drug (NSAID) use. The antihypertensive effect of ACE inhibitors may be diminished by NSAIDs. In persons who are elderly, volume-depleted, or with compromised renal function, coadministration of ACE inhibitors and NSAIDs may result in deterioration of renal function, including possible acute renal failure; these effects are usually reversible.
Bendroflumethiazide; Nadolol: (Moderate) Monitor blood pressure during concomitant beta-blocker and nonsteroidal anti-inflammatory drug (NSAID) use. The antihypertensive effect of beta-blockers may be diminished by NSAIDs.
Benzoic Acid; Hyoscyamine; Methenamine; Methylene Blue; Phenyl Salicylate: (Major) The concurrent use of salicylates and indomethacin is not recommended.

The Beers criteria recommends that this drug combination be avoided in older adults; if coadministration cannot be avoided, provide gastrointestinal protection.
Betaxolol: (Moderate) Monitor blood pressure during concomitant beta-blocker and nonsteroidal anti-inflammatory drug (NSAID) use. The antihypertensive effect of beta-blockers may be diminished by NSAIDs.
Betrixaban: (Major) Monitor patients closely and promptly evaluate any signs or symptoms of bleeding if betrixaban and nonsteroidal antiinflammatory drugs (NSAIDs) are used concomitantly. Coadministration of betrixaban and NSAIDs may increase the risk of bleeding.
Bictegravir; Emtricitabine; Tenofovir Alafenamide: (Moderate) Monitor for nonsteroidal antiinflammatory drug (NSAID) or emtricitabine-related adverse events during concomitant use. Concomitant use may increase NSAID or emtricitabine concentrations. Coadministration of drugs that reduce renal function or compete for active tubular secretion, such as NSAIDs and emtricitabine, may increase the risk of adverse reactions.
Bismuth Subsalicylate: (Major) The concurrent use of salicylates and indomethacin is not recommended. Combined use does not produce any greater therapeutic effect than indomethacin monotherapy. Also, a significantly greater incidence of gastrointestinal adverse effects with concurrent use has been observed.

The Beers criteria recommends that this drug combination be avoided in older adults; if coadministration cannot be avoided, provide gastrointestinal protection.
Budesonide; Glycopyrrolate; Formoterol: (Moderate) Monitor for gastrointestinal toxicity during concurrent corticosteroid and nonsteroidal antiinflammatory drug (NSAID) use. Concomitant use increases the risk of GI bleeding. The Beers criteria recommends that this drug combination be avoided in older adults; if coadministration cannot be avoided, provide gastrointestinal protection.
Bumetanide: (Moderate) If a nonsteroidal anti-inflammatory drug (NSAID) and a diuretic are used concurrently, carefully monitor the patient for signs and symptoms of decreased renal function and diuretic efficacy. Patients taking diuretics and NSAIDs concurrently are at higher risk of developing renal insufficiency. NSAIDs may reduce the natriuretic effect of diuretics in some patients. NSAIDs have been associated with an inhibition of prostaglandin synthesis, which may result in reduced renal blood flow leading to renal insufficiency and increases in blood pressure that are often accompanied by peripheral edema and weight gain.
Bupivacaine; Meloxicam: (Major) Avoid concomitant use of indomethacin with any other NSAID, including COX-2 inhibitors, due to the risk of additive serious NSAID toxicities including but not limited to GI bleeding, GI perforation, or peptic ulcers.
Busulfan: (Major) Due to the thrombocytopenic effects of busulfan, an additive risk of bleeding may be seen in patients receiving concomitant anticoagulants, NSAIDs, platelet inhibitors, including aspirin, ASA, strontium-89 chloride, and thrombolytic agents. In addition, large doses of salicylates (>= 3-4 g/day) can cause hypoprothrombinemia, an additional risk factor for bleeding.
Calcium Carbonate: (Moderate) Antacids may inhibit the oral absorption of indomethacin. Simultaneous administration should be avoided; separate dosing by at least 2 hours to limit an interaction.
Calcium Carbonate; Famotidine; Magnesium Hydroxide: (Moderate) Antacids may inhibit the oral absorption of indomethacin. Simultaneous administration should be avoided; separate dosing by at least 2 hours to limit an interaction.
Calcium Carbonate; Magnesium Hydroxide: (Moderate) Antacids may inhibit the oral absorption of indomethacin. Simultaneous administration should be avoided; separate dosing by at least 2 hours to limit an interaction.

Simultaneous administration should be avoided; separate dosing by at least 2 hours to limit an interaction. (Minor) Monitor for gastrointestinal adverse events during concurrent use of risedronate and nonsteroidal antiinflammatory drugs. Both medications have been associated with gastrointestinal irritation although data suggest concomitant use introduces little additional risk for adverse effects for most patients.
Calcium Carbonate; Simethicone: (Moderate) Antacids may inhibit the oral absorption of indomethacin. Simultaneous administration should be avoided; separate dosing by at least 2 hours to limit an interaction.
Calcium Phosphate, Supersaturated: (Moderate) Concomitant use of medicines with potential to alter renal perfusion or function such as nonsteroidal anti-inflammatory drugs (NSAIDs) may increase the risk of acute phosphate nephropathy in patients taking sodium phosphate monobasic monohydrate; sodium phosphate dibasic anhydrous.
Calcium; Vitamin D: (Moderate) Antacids may inhibit the oral absorption of indomethacin. Simultaneous administration should be avoided; separate dosing by at least 2 hours to limit an interaction.
Calcium-channel blockers: (Moderate) If nonsteroidal anti-inflammatory drugs (NSAIDs) and an antihypertensive drug are concurrently used, carefully monitor the patient for signs and symptoms of renal insufficiency and blood pressure control. Doses of antihypertensive medications may require adjustment in patients receiving concurrent NSAIDs. NSAIDs, to varying degrees, have been associated with an elevation in blood pressure. This effect is most significant in patients receiving concurrent antihypertensive agents and long-term NSAID therapy. NSAIDs cause a dose-dependent reduction in prostaglandin formation, which may result in a reduction in renal blood flow leading to renal insufficiency and an increase in blood pressure that are often accompanied by peripheral edema and weight gain. Patients who rely upon renal prostaglandins to maintain renal perfusion may have acute renal blood flow reduction with NSAID usage. Elderly patients may be at increased risk of adverse effects from combined long-term NSAID therapy and antihypertensive agents, especially diuretics, due to age-related decreases in renal function and an increased risk of stroke and coronary artery disease.
Candesartan: (Moderate) Monitor blood pressure and renal function periodically during concomitant angiotensin II blocker and nonsteroidal anti-inflammatory drug (NSAID) use. The antihypertensive effect of angiotensin II blockers may be diminished by NSAIDs. In persons who are elderly, volume-depleted, or with compromised renal function, coadministration of angiotensin II blockers and NSAIDs may result in deterioration of renal function, including possible acute renal failure; these effects are usually reversible.
Candesartan; Hydrochlorothiazide, HCTZ: (Moderate) Monitor blood pressure and renal function periodically during concomitant angiotensin II blocker and nonsteroidal anti-inflammatory drug (NSAID) use. The antihypertensive effect of angiotensin II blockers may be diminished by NSAIDs. In persons who are elderly, volume-depleted, or with compromised renal function, coadministration of angiotensin II blockers and NSAIDs may result in deterioration of renal function, including possible acute renal failure; these effects are usually reversible.
Cannabidiol: (Moderate) Consider a dose reduction of indomethacin as clinically appropriate, if adverse reactions occur when administered with cannabidiol. Increased indomethacin exposure is possible. Indomethacin is a CYP2C9 substrate. In vitro data predicts inhibition of CYP2C9 by cannabidiol potentially resulting in clinically significant interactions.
Capreomycin: (Major) Because capreomycin is primarily eliminated by the kidney, coadministration with other potentially nephrotoxic drugs, including nonsteroidal antiinflammatory drugs (NSAIDs), may increase serum concentrations of either drug. Theoretically, the chronic coadministration of these drugs may increase the risk of developing nephrotoxicity, even in patients who have normal renal function. Monitor patients for changes in renal function if these drugs are coadministered.
Captopril: (Moderate) Monitor blood pressure and renal function periodically during concomitant angiotensin-converting enzyme (ACE) inhibitor and nonsteroidal anti-inflammatory drug (NSAID) use. The antihypertensive effect of ACE inhibitors may be diminished by NSAIDs. In persons who are elderly, volume-depleted, or with compromised renal function, coadministration of ACE inhibitors and NSAIDs may result in deterioration of renal function, including possible acute renal failure; these effects are usually reversible.
Captopril; Hydrochlorothiazide, HCTZ: (Moderate) Monitor blood pressure and renal function periodically during concomitant angiotensin-converting enzyme (ACE) inhibitor and nonsteroidal anti-inflammatory drug (NSAID) use. The antihypertensive effect of ACE inhibitors may be diminished by NSAIDs. In persons who are elderly, volume-depleted, or with compromised renal function, coadministration of ACE inhibitors and NSAIDs may result in deterioration of renal function, including possible acute renal failure; these effects are usually reversible.
Carmustine, BCNU: (Major) Due to the thrombocytopenic effects of carmustine, an additive risk of bleeding may be seen in patients receiving concomitant anticoagulants, NSAIDs, platelet inhibitors, including aspirin, ASA, strontium-89 chloride, and thrombolytic agents. In addition, large doses of salicylates (>= 3-4 g/day) can cause hypoprothrombinemia, an additional risk factor for bleeding. These additive effects may not occur for at least 6 weeks after the administration of carmustine due to the delayed myelosuppressive effects of carmustine.
Carteolol: (Moderate) Monitor blood pressure during concomitant beta-blocker and nonsteroidal anti-inflammatory drug (NSAID) use. The antihypertensive effect of beta-blockers may be diminished by NSAIDs.
Carvedilol: (Moderate) Monitor blood pressure during concomitant beta-blocker and nonsteroidal anti-inflammatory drug (NSAID) use. The antihypertensive effect of beta-blockers may be diminished by NSAIDs.
Cefotaxime: (Minor) Cefotaxime's product label states that cephalosporins may potentiate the adverse renal effects of nephrotoxic agents, such as aminoglycosides, nonsteroidal antiinflammatory drugs (NSAIDs), and loop diuretics. Carefully monitor renal function, especially during prolonged therapy or use of high aminoglycoside doses. The majority of reported cases involve the combination of aminoglycosides and cephalothin or cephaloridine, which are associated with dose-related nephrotoxicity as singular agents. Limited but conflicting data with other cephalosporins have been noted.
Celecoxib: (Major) Avoid concomitant use of celecoxib with any other NSAID due to the risk of additive serious NSAID toxicities including but not limited to GI bleeding, GI perforation, or peptic ulcers.
Celecoxib; Tramadol: (Major) Avoid concomitant use of celecoxib with any other NSAID due to the risk of additive serious NSAID toxicities including but not limited to GI bleeding, GI perforation, or peptic ulcers.
Chlorambucil: (Major) Due to the thrombocytopenic effects of chlorambucil, an additive risk of bleeding may be seen in patients receiving concomitant anticoagulants, NSAIDs, platelet inhibitors, including aspirin, ASA, strontium-89 chloride, and thrombolytic agents. In addition, large doses of salicylates (>= 3-4 g/day) can cause hypoprothrombinemia, an additional risk factor for bleeding.
Chlorpheniramine; Ibuprofen; Pseudoephedrine: (Major) Avoid concomitant use of ibuprofen with any other NSAID, including COX-2 inhibitors, due to the risk of additive serious NSAID toxicities including but not limited to GI bleeding, GI perforation, or peptic ulcers.
Chlorpropamide: (Moderate) NSAIDs may enhance hypoglycemia in diabetic patients via inhibition of prostaglandin synthesis, which indirectly increases insulin secretion. If NSAIDs are administered or discontinued in patients receiving oral antidiabetic agents, patients should be monitored for hypoglycemia or loss of blood glucose control. No clinically significant interaction between sulindac at daily doses of 400 mg and oral hypoglycemic agents has been observed. Sulindac, its sulfide metabolite, and sulfonylureas are highly bound to protein. Sulindac could displace the sulfonylureas, altering hypoglycemic activity. Careful patient monitoring is recommended to ensure that no change in their diabetes medicine dosage is required. A sulfonylurea dose adjustment may be needed, especially if sulindac doses greater than 400 mg daily are used or if the drug combination is used in patients with renal impairment or other metabolic defects that might increase sulindac blood concentrations.
Choline Salicylate; Magnesium Salicylate: (Major) The concurrent use of salicylates and indomethacin is not recommended. Combined use does not produce any greater therapeutic effect than indomethacin monotherapy. Also, a significantly greater incidence of gastrointestinal adverse effects with concurrent use has been observed. Because NSAIDs can cause GI bleeding, inhibit platelet aggregation, and prolong bleeding time, additive effects may be seen in patients receiving platelet inhibitors (e.g., aspirin), anticoagulants, or thrombolytic agents.
Cholinesterase inhibitors: (Moderate) NSAIDs may cause additive pharmacodynamic GI effects with cholinesterase inhibitors, leading to gastrointestinal intolerance. Patients receiving concurrent NSAIDs should be monitored closely for symptoms of active or occult gastrointestinal bleeding. While NSAIDs appear to suppress microglial activity, which in turn may slow inflammatory neurodegenerative processes important for the progression of Alzheimer's disease (AD), there are no clinical data at this time to suggest that NSAIDs alone or as combined therapy with AD agents result in synergistic effects in AD.
Ciclesonide: (Moderate) Monitor for gastrointestinal toxicity during concurrent corticosteroid and nonsteroidal antiinflammatory drug (NSAID) use. Concomitant use increases the risk of GI bleeding. The Beers criteria recommends that this drug combination be avoided in older adults; if coadministration cannot be avoided, provide gastrointestinal protection.
Cidofovir: (Contraindicated) The concomitant administration of cidofovir and nonsteroidal antiinflammatory drugs (NSAIDs) is contraindicated due to the potential for increased nephrotoxicity. NSAIDs should be discontinued 7 days prior to beginning cidofovir.
Cilostazol: (Moderate) Monitor for signs and symptoms of bleeding during concomitant platelet inhibitor and chronic nonsteroidal antiinflammatory drug (NSAID) use. Concomitant use increases the risk of bleeding.
Citalopram: (Moderate) Monitor for signs and symptoms of bleeding during concomitant selective serotonin reuptake inhibitor (SSRI) and nonsteroidal antiinflammatory drug (NSAID) use due to increased risk for bleeding. Serotonin release by platelets plays an important role in hemostasis. Epidemiological studies have demonstrated an association between use of psychotropic drugs that interfere with serotonin reuptake and the occurrence of upper gastrointestinal bleeding.
Cladribine: (Major) Due to the thrombocytopenic effects of cladribine, an additive risk of bleeding may be seen in patients receiving concomitant anticoagulants, NSAIDs, platelet inhibitors, including aspirin, strontium-89 chloride, and thrombolytic agents. In addition, large doses of salicylates (>= 3-4 g/day) can cause hypoprothrombinemia, an additional risk factor for bleeding.
Clofarabine: (Major) Due to the thrombocytopenic effects of clofarabine, an additive risk of bleeding may be seen in patients receiving concomitant NSAIDs. In addition, large doses of salicylates (>= 3-4 g/day) can cause hypoprothrombinemia, an additional risk factor for bleeding.
Clopidogrel: (Moderate) Monitor for signs and symptoms of bleeding during concomitant platelet inhibitor and chronic nonsteroidal antiinflammatory drug (NSAID) use. Concomitant use increases the risk of bleeding.
Colistimethate, Colistin, Polymyxin E: (Major) The administration of colistimethate sodium may increase the risk of developing nephrotoxicity, even in patients who have normal renal function. Nonsteroidal antiinflammatory drugs (NSAIDs) may increase the risk for nephrotoxicity when used concurrently. Monitor patients for changes in renal function if these drugs are coadministered. Since colistimethate sodium is eliminated by the kidney, coadministration with other potentially nephrotoxic drugs, including nonsteroidal antiinflammatory drugs (NSAIDs), may theoretically increase serum concentrations of either drug.
Colistin: (Major) The administration of colistimethate sodium may increase the risk of developing nephrotoxicity, even in patients who have normal renal function. Nonsteroidal antiinflammatory drugs (NSAIDs) may increase the risk for nephrotoxicity when used concurrently. Monitor patients for changes in renal function if these drugs are coadministered. Since colistimethate sodium is eliminated by the kidney, coadministration with other potentially nephrotoxic drugs, including nonsteroidal antiinflammatory drugs (NSAIDs), may theoretically increase serum concentrations of either drug.
Corticosteroids: (Moderate) Monitor for gastrointestinal toxicity during concurrent corticosteroid and nonsteroidal antiinflammatory drug (NSAID) use. Concomitant use increases the risk of GI bleeding. The Beers criteria recommends that this drug combination be avoided in older adults; if coadministration cannot be avoided, provide gastrointestinal protection.
Cortisone: (Moderate) Monitor for gastrointestinal toxicity during concurrent corticosteroid and nonsteroidal antiinflammatory drug (NSAID) use. Concomitant use increases the risk of GI bleeding. The Beers criteria recommends that this drug combination be avoided in older adults; if coadministration cannot be avoided, provide gastrointestinal protection.
Cyclophosphamide: (Moderate) Use caution if coadministration of cyclophosphamide with indomethacin is necessary as acute water intoxication has been reported with concomitant use.
Cyclosporine: (Moderate) Additive decreases in renal function have been reported between cyclosporine and nonsteroidal anti-inflammatory drugs. Patients should be monitored for signs and symptoms of cyclosporine toxicity and infection, as NSAIDs may mask fever, pain, or swelling.
Cytarabine, ARA-C: (Major) The main toxic effect of cytarabine, ARA-C is bone marrow suppression with leukopenia, thrombocytopenia and anemia. Due to the thrombocytopenic effects of cytarabine, an additive risk of bleeding may be seen in patients receiving concomitant NSAIDs. In addition, large doses of salicylates (>= 3-4 g/day) can cause hypoprothrombinemia, an additional risk factor for bleeding. Dipyridamole can block membrane transport of cytarabine in tumor cells, therefore decreasing its antineoplastic activity.
Dabigatran: (Major) Educate patients about the signs of increased bleeding and the need to report these signs to a healthcare provider immediately if coadministration of dabigatran and a nonsteroidal antiinflammatory drug (NSAID) is necessary. Dabigatran can cause significant and, sometimes, fatal bleeding. This risk may be increased by concurrent use of chronic NSAID therapy.
Dacarbazine, DTIC: (Major) Leukopenia and thrombocytopenia are common toxicities of dacarbazine, DTIC. Due to the thrombocytopenic effects of dacarbazine, an additive risk of bleeding may be seen in patients receiving concomitant anticoagulants, NSAIDs, platelet inhibitors, including aspirin, ASA, strontium-89 chloride, and thrombolytic agents. In addition, large doses of salicylates (>= 3-4 g/day) can cause hypoprothrombinemia, an additional risk factor for bleeding.
Dalteparin: (Moderate) An additive risk of bleeding may be seen in patients receiving anticoagulants in combination with other agents known to increase the risk of bleeding such as nonsteroidal antiinflammatory drugs (NSAIDs). Monitor clinical and laboratory response closely during concurrent use.
Darunavir; Cobicistat; Emtricitabine; Tenofovir alafenamide: (Moderate) Monitor for nonsteroidal antiinflammatory drug (NSAID) or emtricitabine-related adverse events during concomitant use. Concomitant use may increase NSAID or emtricitabine concentrations. Coadministration of drugs that reduce renal function or compete for active tubular secretion, such as NSAIDs and emtricitabine, may increase the risk of adverse reactions.
Dasatinib: (Major) Due to the thrombocytopenic and possible platelet inhibiting effects of dasatinib, an additive risk of bleeding may be seen in patients receiving concomitant anticoagulants, NSAIDs, platelet inhibitors (including aspirin), strontium-89 chloride, and thrombolytic agents. In addition, large doses of salicylates (>= 3-4 g/day) can cause hypoprothrombinemia, an additional risk factor for bleeding. Caution should be exercised if patients are required to take medications that inhibit platelet function or anticoagulants concomitantly with dasatinib.
Dasiglucagon: (Moderate) When used with indomethacin, glucagon may lose its ability to raise blood glucose or may even produce hypoglycemia. Therefore, caution should be exercised for patients taking indomethacin when glucagon will be administered.
Deferasirox: (Moderate) Because gastric ulceration and GI bleeding have been reported in patients taking deferasirox, use caution when coadministering with other drugs known to increase the risk of peptic ulcers or gastric hemorrhage including NSAIDs. In addition, coadministration of deferasirox with other potentially nephrotoxic drugs, including NSAIDs, may increase the acute renal failure. Monitor serum creatinine and/or creatinine clearance in patients who are receiving deferasirox and nephrotoxic drugs concomitantly
Deflazacort: (Moderate) Monitor for gastrointestinal toxicity during concurrent corticosteroid and nonsteroidal antiinflammatory drug (NSAID) use. Concomitant use increases the risk of GI bleeding. The Beers criteria recommends that this drug combination be avoided in older adults; if coadministration cannot be avoided, provide gastrointestinal protection.
Desirudin: (Moderate) An additive risk of bleeding may be seen in patients receiving anticoagulants in combination with other agents known to increase the risk of bleeding such as nonsteroidal antiinflammatory drugs (NSAIDs). Monitor clinical and laboratory response closely during concurrent use.
Desmopressin: (Major) Additive hyponatremic effects may be seen in patients treated with desmopressin and drugs associated with hyponatremia including NSAIDs. Use combination with caution, and monitor patients for signs and symptoms of hyponatremia. A woman who took both desmopressin and ibuprofen was found in a comatose state. As her serum sodium concentration was 121 mmol/L, and her plasma osmolality was low in the presence of a high-normal urine osmolality and normal sodium excretion, she was treated with fluid restriction. Her serum sodium concentration was 124 mmol/L within a day and was 135 mmol/L by the second day. The woman had previously received desmopressin without the development of clinical symptoms of hyponatremia
Desvenlafaxine: (Moderate) Platelet aggregation may be impaired by desvenlafaxine due to platelet serotonin depletion, possibly increasing the risk of a bleeding complication (e.g., gastrointestinal bleeding, ecchymoses, epistaxis, hematomas, petechiae, hemorrhage) in patients receiving nonsteroidal antiinflammatory drugs (NSAIDs). Patients should be monitored for signs and symptoms of bleeding while taking desvenlafaxine with NSAIDs.
Dexamethasone: (Moderate) Monitor for gastrointestinal toxicity during concurrent corticosteroid and nonsteroidal antiinflammatory drug (NSAID) use. Concomitant use increases the risk of GI bleeding. The Beers criteria recommends that this drug combination be avoided in older adults; if coadministration cannot be avoided, provide gastrointestinal protection.
Diclofenac: (Major) Avoid concomitant use of diclofenac with any other NSAID due to the risk of additive serious NSAID toxicities including but not limited to GI bleeding, GI perforation, or peptic ulcers.
Diclofenac; Misoprostol: (Major) Avoid concomitant use of diclofenac with any other NSAID due to the risk of additive serious NSAID toxicities including but not limited to GI bleeding, GI perforation, or peptic ulcers.
Dicloxacillin: (Minor) Indomethacin may compete with penicillin for renal tubular secretion, increasing penicillin serum concentrations. This combination should be used with caution and patients monitored for increased side effects.
Diflunisal: (Contraindicated) The concurrent use of diflunisal and other nonsteroidal anti-inflammatory drugs (NSAIDs) is not recommended due to the increased risk of gastrointestinal toxicity with little or no increase in anti-inflammatory efficacy. The concurrent usage of diflunisal and indomethacin is contraindicated. In addition to reducing the renal clearance and significantly increasing the plasma concentrations of indomethacin, the concomitant use of diflunisal and indomethacin has resulted in fatal gastric hemorrhage.
Digoxin: (Major) Coadministration of digoxin and indomethacin increases the serum concentration of digoxin by 40%. Measure serum digoxin concentrations before initiating indomethacin. Reduce digoxin concentrations by decreasing the digoxin dose by approximately 15-30% or by modifying the dosing frequency and continue monitoring. In addition, concomitant use of other nonsteroidal antiinflammatory drugs (NSAIDs), including COX-2 inhibitors, with digoxin may result in increased serum concentrations of digoxin. Increased serum digoxin concentrations have been reported in patients who received digoxin and diclofenac sodium or ibuprofen. NSAIDs may cause a significant deterioration in renal function. A decline in glomerular filtration or tubular secretion may impair the excretion of digoxin. Monitor patients during concomitant treatment for possible digoxin toxicity and reduce digoxin dose as necessary.
Diphenhydramine; Ibuprofen: (Major) Avoid concomitant use of ibuprofen with any other NSAID, including COX-2 inhibitors, due to the risk of additive serious NSAID toxicities including but not limited to GI bleeding, GI perforation, or peptic ulcers.
Diphenhydramine; Naproxen: (Major) Avoid concomitant use of indomethacin with any other NSAID, including COX-2 inhibitors, due to the risk of additive serious NSAID toxicities including but not limited to GI bleeding, GI perforation, or peptic ulcers.
Dipyridamole: (Moderate) Monitor for signs and symptoms of bleeding during concomitant platelet inhibitor and chronic nonsteroidal antiinflammatory drug (NSAID) use. Concomitant use increases the risk of bleeding.
Docetaxel: (Major) Due to the thrombocytopenic effects of docetaxel, an additive risk of bleeding may be seen in patients receiving concomitant anticoagulants, NSAIDs, platelet inhibitors (including aspirin), strontium-89 chloride, and thrombolytic agents. In addition, large doses of salicylates (>= 3-4 g/day) can cause hypoprothrombinemia, an additional risk factor for bleeding.
Donepezil: (Moderate) NSAIDs may cause additive pharmacodynamic GI effects with cholinesterase inhibitors, leading to gastrointestinal intolerance. Patients receiving concurrent NSAIDs should be monitored closely for symptoms of active or occult gastrointestinal bleeding. While NSAIDs appear to suppress microglial activity, which in turn may slow inflammatory neurodegenerative processes important for the progression of Alzheimer's disease (AD), there are no clinical data at this time to suggest that NSAIDs alone or as combined therapy with AD agents result in synergistic effects in AD.
Donepezil; Memantine: (Moderate) NSAIDs may cause additive pharmacodynamic GI effects with cholinesterase inhibitors, leading to gastrointestinal intolerance. Patients receiving concurrent NSAIDs should be monitored closely for symptoms of active or occult gastrointestinal bleeding. While NSAIDs appear to suppress microglial activity, which in turn may slow inflammatory neurodegenerative processes important for the progression of Alzheimer's disease (AD), there are no clinical data at this time to suggest that NSAIDs alone or as combined therapy with AD agents result in synergistic effects in AD.
Doravirine; Lamivudine; Tenofovir disoproxil fumarate: (Moderate) Avoid administering tenofovir, PMPA concurrently with or recently after a nephrotoxic agent, such as high-dose or multiple nonsteroidal antiinflammatory drugs (NSAIDs). Cases of acute renal failure, some requiring hospitalization and renal replacement therapy, have been reported after high-dose or multiple NSAIDs were initiated in patients who appeared stable on tenofovir. Consider alternatives to NSAIDs in patients at risk for renal dysfunction. If these drugs must be coadministered, carefully monitor the estimated creatinine creatinine, serum phosphorus, urine glucose, and urine protein prior to, and periodically during, treatment.
Dorzolamide; Timolol: (Moderate) Monitor blood pressure during concomitant beta-blocker and nonsteroidal anti-inflammatory drug (NSAID) use. The antihypertensive effect of beta-blockers may be diminished by NSAIDs.
Doxazosin: (Moderate) If nonsteroidal anti-inflammatory drugs (NSAIDs) and an antihypertensive drug are concurrently used, carefully monitor the patient for signs and symptoms of renal insufficiency and blood pressure control. Doses of antihypertensive medications may require adjustment in patients receiving concurrent NSAIDs. NSAIDs, to varying degrees, have been associated with an elevation in blood pressure. This effect is most significant in patients receiving concurrent antihypertensive agents and long-term NSAID therapy. NSAIDs cause a dose-dependent reduction in prostaglandin formation, which may result in a reduction in renal blood flow leading to renal insufficiency and an increase in blood pressure that are often accompanied by peripheral edema and weight gain. Patients who rely upon renal prostaglandins to maintain renal perfusion may have acute renal blood flow reduction with NSAID usage. Elderly patients may be at increased risk of adverse effects from combined long-term NSAID therapy and antihypertensive agents, especially diuretics, due to age-related decreases in renal function and an increased risk of stroke and coronary artery disease.
Drospirenone: (Minor) Drospirenone has antimineralocorticoid effects; the progestin may increase serum potassium. Other drugs that may have additive effects on serum potassium with drospirenone include chronic treatment with NSAIDs, and monitoring of serum potassium in the 1st month of concurrent therapy is recommended.

Drospirenone; Ethinyl Estradiol: (Minor) Drospirenone has antimineralocorticoid effects; the progestin may increase serum potassium. Other drugs that may have additive effects on serum potassium with drospirenone include chronic treatment with NSAIDs, and monitoring of serum potassium in the 1st month of concurrent therapy is recommended.
Drospirenone; Ethinyl Estradiol; Levomefolate: (Minor) Drospirenone has antimineralocorticoid effects; the progestin may increase serum potassium. Other drugs that may have additive effects on serum potassium with drospirenone include chronic treatment with NSAIDs, and monitoring of serum potassium in the 1st month of concurrent therapy is recommended. (Minor) L-methylfolate should be used cautiously in patients taking high doses of indomethacin. Plasma concentrations of L-methylfolate may be reduced when used concomitantly with high doses of indomethacin. Monitor patients for decreased efficacy of L-methylfolate if these agents are used together.
Duloxetine: (Moderate) Monitor for signs and symptoms of bleeding during concomitant duloxetine and nonsteroidal antiinflammatory drug (NSAID) use due to increased risk for bleeding. Serotonin release by platelets plays an important role in hemostasis. Epidemiological studies have demonstrated an association between use of psychotropic drugs that interfere with serotonin reuptake and the occurrence of upper gastrointestinal bleeding.
Edoxaban: (Major) An additive risk of bleeding may be seen in patients receiving anticoagulants in combination with other agents known to increase the risk of bleeding such as nonsteroidal antiinflammatory drugs (NSAIDs). Monitor clinical and laboratory response closely during concurrent use.
Edrophonium: (Moderate) NSAIDs may cause additive pharmacodynamic GI effects with cholinesterase inhibitors, leading to gastrointestinal intolerance. Patients receiving concurrent NSAIDs should be monitored closely for symptoms of active or occult gastrointestinal bleeding. While NSAIDs appear to suppress microglial activity, which in turn may slow inflammatory neurodegenerative processes important for the progression of Alzheimer's disease (AD), there are no clinical data at this time to suggest that NSAIDs alone or as combined therapy with AD agents result in synergistic effects in AD.
Efavirenz; Emtricitabine; Tenofovir Disoproxil Fumarate: (Moderate) Avoid administering tenofovir, PMPA concurrently with or recently after a nephrotoxic agent, such as high-dose or multiple nonsteroidal antiinflammatory drugs (NSAIDs). Cases of acute renal failure, some requiring hospitalization and renal replacement therapy, have been reported after high-dose or multiple NSAIDs were initiated in patients who appeared stable on tenofovir. Consider alternatives to NSAIDs in patients at risk for renal dysfunction. If these drugs must be coadministered, carefully monitor the estimated creatinine creatinine, serum phosphorus, urine glucose, and urine protein prior to, and periodically during, treatment. (Moderate) Monitor for nonsteroidal antiinflammatory drug (NSAID) or emtricitabine-related adverse events during concomitant use. Concomitant use may increase NSAID or emtricitabine concentrations. Coadministration of drugs that reduce renal function or compete for active tubular secretion, such as NSAIDs and emtricitabine, may increase the risk of adverse reactions.
Efavirenz; Lamivudine; Tenofovir Disoproxil Fumarate: (Moderate) Avoid administering tenofovir, PMPA concurrently with or recently after a nephrotoxic agent, such as high-dose or multiple nonsteroidal antiinflammatory drugs (NSAIDs). Cases of acute renal failure, some requiring hospitalization and renal replacement therapy, have been reported after high-dose or multiple NSAIDs were initiated in patients who appeared stable on tenofovir. Consider alternatives to NSAIDs in patients at risk for renal dysfunction. If these drugs must be coadministered, carefully monitor the estimated creatinine creatinine, serum phosphorus, urine glucose, and urine protein prior to, and periodically during, treatment.
Elexacaftor; tezacaftor; ivacaftor: (Minor) Increased monitoring is recommended if ivacaftor is administered concurrently with CYP2C9 substrates, such as indomethacin. In vitro studies showed ivacaftor to be a weak inhibitor of CYP2C9. Co-administration may lead to increased exposure to CYP2C9 substrates; however, the clinical impact of this has not yet been determined.
Eltrombopag: (Moderate) Eltrombopag is a UDP-glucuronyltransferase inhibitor. NSAIDs are a substrate of UDP-glucuronyltransferases. The significance or effect of this interaction is not known; however, elevated concentrations of the NSAID are possible. Monitor patients for adverse reactions if eltrombopag is administered with an NSAID.
Elvitegravir; Cobicistat; Emtricitabine; Tenofovir Alafenamide: (Moderate) Monitor for nonsteroidal antiinflammatory drug (NSAID) or emtricitabine-related adverse events during concomitant use.

Enoxaparin: (Major) Whenever possible, discontinue agents which may enhance the risk of hemorrhage, including nonsteroidal antiinflammatory drugs, before initiation of enoxaparin therapy. If coadministration is essential, conduct close clinical and laboratory monitoring.
Entecavir: (Moderate) The manufacturer of entecavir recommends monitoring for adverse effects when coadministered with NSAIDs. Entecavir is primarily eliminated by the kidneys; NSAIDs can affect renal function. Concurrent administration may increase the serum concentrations of entecavir and adverse events.
Eplerenone: (Major) Monitor serum potassium and serum creatinine concentrations within 3 to 7 days of initiating coadministration of eplerenone and nonsteroidal antiinflammatory drugs (NSAIDs), and monitor blood pressure. The concomitant use of other potassium-sparing antihypertensives with NSAIDs has been shown to reduce the antihypertensive effect in some patients and result in severe hyperkalemia in patients with impaired renal function. Patients who develop hyperkalemia may continue eplerenone with proper dose adjustment; eplerenone dose reduction decreases potassium concentrations.
Epoprostenol: (Moderate) NSAIDs may decrease the effect of antihypertensive agents through various mechanisms, including renal and peripheral vasoactive pathways.
Eprosartan: (Moderate) Monitor blood pressure and renal function periodically during concomitant angiotensin II blocker and nonsteroidal anti-inflammatory drug (NSAID) use. The antihypertensive effect of angiotensin II blockers may be diminished by NSAIDs. In persons who are elderly, volume-depleted, or with compromised renal function, coadministration of angiotensin II blockers and NSAIDs may result in deterioration of renal function, including possible acute renal failure; these effects are usually reversible.
Eprosartan; Hydrochlorothiazide, HCTZ: (Moderate) Monitor blood pressure and renal function periodically during concomitant angiotensin II blocker and nonsteroidal anti-inflammatory drug (NSAID) use.

In persons who are elderly, volume-depleted, or with compromised renal function, coadministration of angiotensin II blockers and NSAIDs may result in deterioration of renal function, including possible acute renal failure; these effects are usually reversible.
Eptifibatide: (Moderate) Monitor for signs and symptoms of bleeding during concomitant platelet inhibitor and chronic nonsteroidal antiinflammatory drug (NSAID) use. Concomitant use increases the risk of bleeding.
Erlotinib: (Moderate) Monitor for symptoms of gastrointestinal (GI) perforation (e.g., severe abdominal pain, fever, nausea, and vomiting) if coadministration of erlotinib with nonsteroidal antiinflammatory drugs (NSAIDs) is necessary. Permanently discontinue erlotinib in patients who develop GI perforation. The pooled incidence of GI perforation clinical trials of erlotinib ranged from 0.1% to 0.4%, including fatal cases. Patients receiving concomitant NSAIDs may be at increased risk of perforation.
Escitalopram: (Moderate) Monitor for signs and symptoms of bleeding during concomitant selective serotonin reuptake inhibitor (SSRI) and nonsteroidal antiinflammatory drug (NSAID) use due to increased risk for bleeding. Serotonin release by platelets plays an important role in hemostasis.

Ethacrynic Acid: (Moderate) If a nonsteroidal anti-inflammatory drug (NSAID) and a diuretic are used concurrently, carefully monitor the patient for signs and symptoms of decreased renal function and diuretic efficacy. Patients taking diuretics and NSAIDs concurrently are at higher risk of developing renal insufficiency. NSAIDs may reduce the natriuretic effect of diuretics in some patients. NSAIDs have been associated with an inhibition of prostaglandin synthesis, which may result in reduced renal blood flow leading to renal insufficiency and increases in blood pressure that are often accompanied by peripheral edema and weight gain.
Ethanol: (Major) Advise patients to avoid alcohol and alcohol-containing products while taking NSAIDs. Concomitant ingestion of alcohol with NSAIDs increases the risk of developing gastric irritation and GI mucosal bleeding. Alcohol is a mucosal irritant and NSAIDs decrease platelet aggregation. Routine ingestion of alcohol and NSAIDs can cause significant GI bleeding, which may or may not be overt. Even occasional concomitant use of NSAIDs and alcohol should be avoided. Chronic alcohol ingestion is often associated with hypoprothrombinemia and this condition increases the risk of bleeding.
Ethinyl Estradiol; Levonorgestrel; Folic Acid; Levomefolate: (Minor) L-methylfolate should be used cautiously in patients taking high doses of indomethacin. Plasma concentrations of L-methylfolate may be reduced when used concomitantly with high doses of indomethacin. Monitor patients for decreased efficacy of L-methylfolate if these agents are used together.
Ethiodized Oil: (Moderate) Nonsteroidal anti-inflammatory drugs (NSAIDs) may increase the risk for nephrotoxicity when given to patients receiving a contrast agents. When possible, withhold NSAID therapy during administration of a contrast agent.
Etidronate: (Minor) Monitor for gastrointestinal adverse events during concurrent use of etidronate and nonsteroidal antiinflammatory drugs. Both medications have been associated with gastrointestinal irritation although data suggest concomitant use introduces little additional risk for adverse effects for most patients.
Etodolac: (Major) Avoid concomitant use of etodolac with any other NSAID, including COX-2 inhibitors, due to the risk of additive serious NSAID toxicities including but not limited to GI bleeding, GI perforation, or peptic ulcers.
Fenofibric Acid: (Minor) At therapeutic concentrations, fenofibric acid is a mild-to-moderate inhibitor of CYP2C9. Concomitant use of fenofibric acid with CYP2C9 substrates, such as indomethacin, has not been formally studied. Fenofibric acid may theoretically increase plasma concentrations of CYP2C9 substrates and could lead to toxicity for drugs that have a narrow therapeutic range. Monitor the therapeutic effect of indomethacin during coadministration with fenofibric acid.
Fenoprofen: (Major) Avoid concomitant use of fenoprofen with any other NSAID, including COX-2 inhibitors, due to the risk of additive serious NSAID toxicities including but not limited to GI bleeding, GI perforation, or peptic ulcers.
Flavocoxid, Flavocoxid; Citrated Zinc Bisglycinate: (Major) Flavocoxid exerts similar pharmacologic characteristics to other systemic NSAIDs. Additive pharmacodynamic effects, including a potential for additive adverse cardiac and GI effects, may be seen if flavocoxid is used with NSAIDs. In general, the concurrent use of flavocoxid and NSAIDs should be avoided.
Floxuridine: (Major) Due to the thrombocytopenic effects of floxuridine, an additive risk of bleeding may be seen in patients receiving concomitant anticoagulants, NSAIDs, platelet inhibitors, including aspirin, strontium-89 chloride, and thrombolytic agents. In addition, large doses of salicylates (>= 3-4 g/day) can cause hypoprothrombinemia, an additional risk factor for bleeding.
Fludrocortisone: (Moderate) Monitor for gastrointestinal toxicity during concurrent corticosteroid and nonsteroidal antiinflammatory drug (NSAID) use.

Fosinopril: (Moderate) Monitor blood pressure and renal function periodically during concomitant angiotensin-converting enzyme (ACE) inhibitor and nonsteroidal anti-inflammatory drug (NSAID) use. The antihypertensive effect of ACE inhibitors may be diminished by NSAIDs. In persons who are elderly, volume-depleted, or with compromised renal function, coadministration of ACE inhibitors and NSAIDs may result in deterioration of renal function, including possible acute renal failure; these effects are usually reversible.
Fosinopril; Hydrochlorothiazide, HCTZ: (Moderate) Monitor blood pressure and renal function periodically during concomitant angiotensin-converting enzyme (ACE) inhibitor and nonsteroidal anti-inflammatory drug (NSAID) use. The antihypertensive effect of ACE inhibitors may be diminished by NSAIDs.

Furosemide: (Moderate) If a nonsteroidal anti-inflammatory drug (NSAID) and a diuretic are used concurrently, carefully monitor the patient for signs and symptoms of decreased renal function and diuretic efficacy. Patients taking diuretics and NSAIDs concurrently are at higher risk of developing renal insufficiency. NSAIDs may reduce the natriuretic effect of diuretics in some patients. NSAIDs have been associated with an inhibition of prostaglandin synthesis, which may result in reduced renal blood flow leading to renal insufficiency and increases in blood pressure that are often accompanied by peripheral edema and weight gain.
Galantamine: (Moderate) NSAIDs may cause additive pharmacodynamic GI effects with cholinesterase inhibitors, leading to gastrointestinal intolerance. Patients receiving concurrent NSAIDs should be monitored closely for symptoms of active or occult gastrointestinal bleeding. While NSAIDs appear to suppress microglial activity, which in turn may slow inflammatory neurodegenerative processes important for the progression of Alzheimer's disease (AD), there are no clinical data at this time to suggest that NSAIDs alone or as combined therapy with AD agents result in synergistic effects in AD.
Ganciclovir: (Minor) Concurrent use of nephrotoxic agents, such as NSAIDs, with ganciclovir should be done cautiously to avoid additive nephrotoxicity. Monitor renal function carefully if concomitant therapy is required.
Garlic, Allium sativum: (Minor) Garlic, Allium sativum may produce clinically-significant antiplatelet effects; until more data are available, garlic should be used cautiously in patients receiving drugs with a known potential risk for bleeding such as nonsteroidal antiinflammatory drugs (NSAIDs).
Gentamicin: (Moderate) It is possible that additive nephrotoxicity may occur in patients who receive nonsteroidal anti-inflammatory drugs (NSAIDs) concurrently with other nephrotoxic agents, such as gentamicin.
Ginger, Zingiber officinale: (Minor) Patients receiving regular therapy with nonsteroidal antiinflammatory drugs (NSAIDs) should use ginger with caution, due to a theoretical risk of bleeding resulting from additive pharmacology related to the COX enzymes. However, clinical documentation of interactions is lacking. Several pungent constituents of ginger (Zingiber officinale) are reported to inhibit arachidonic acid (AA) induced platelet activation in human whole blood. The constituent (8)-paradol is the most potent inhibitor of COX-1 and exhibits the greatest anti-platelet activity versus other gingerol analogues. The mechanism of ginger-associated platelet inhibition may be related to decreased COX-1/Thomboxane synthase enzymatic activity.
Ginkgo, Ginkgo biloba: (Moderate) Monitor for signs or symptoms of bleeding with coadministration of ginkgo biloba and NSAIDs as an increased bleeding risk may occur. Although data are mixed, ginkgo biloba is reported to inhibit platelet aggregation and several case reports describe bleeding complications with ginkgo biloba, with or without concomitant drug therapy.
Glimepiride: (Moderate) NSAIDs may enhance hypoglycemia in diabetic patients via inhibition of prostaglandin synthesis, which indirectly increases insulin secretion. If NSAIDs are administered or discontinued in patients receiving oral antidiabetic agents, patients should be monitored for hypoglycemia or loss of blood glucose control. No clinically significant interaction between sulindac at daily doses of 400 mg and oral hypoglycemic agents has been observed. Sulindac, its sulfide metabolite, and sulfonylureas are highly bound to protein. Sulindac could displace the sulfonylureas, altering hypoglycemic activity. Careful patient monitoring is recommended to ensure that no change in their diabetes medicine dosage is required. A sulfonylurea dose adjustment may be needed, especially if sulindac doses greater than 400 mg daily are used or if the drug combination is used in patients with renal impairment or other metabolic defects that might increase sulindac blood concentrations.
Glimepiride; Rosiglitazone: (Moderate) NSAIDs may enhance hypoglycemia in diabetic patients via inhibition of prostaglandin synthesis, which indirectly increases insulin secretion. If NSAIDs are administered or discontinued in patients receiving oral antidiabetic agents, patients should be monitored for hypoglycemia or loss of blood glucose control. No clinically significant interaction between sulindac at daily doses of 400 mg and oral hypoglycemic agents has been observed. Sulindac, its sulfide metabolite, and sulfonylureas are highly bound to protein. Sulindac could displace the sulfonylureas, altering hypoglycemic activity. Careful patient monitoring is recommended to ensure that no change in their diabetes medicine dosage is required. A sulfonylurea dose adjustment may be needed, especially if sulindac doses greater than 400 mg daily are used or if the drug combination is used in patients with renal impairment or other metabolic defects that might increase sulindac blood concentrations.
Glipizide: (Moderate) NSAIDs may enhance hypoglycemia in diabetic patients via inhibition of prostaglandin synthesis, which indirectly increases insulin secretion. If NSAIDs are administered or discontinued in patients receiving oral antidiabetic agents, patients should be monitored for hypoglycemia or loss of blood glucose control. No clinically significant interaction between sulindac at daily doses of 400 mg and oral hypoglycemic agents has been observed. Sulindac, its sulfide metabolite, and sulfonylureas are highly bound to protein. Sulindac could displace the sulfonylureas, altering hypoglycemic activity. Careful patient monitoring is recommended to ensure that no change in their diabetes medicine dosage is required. A sulfonylurea dose adjustment may be needed, especially if sulindac doses greater than 400 mg daily are used or if the drug combination is used in patients with renal impairment or other metabolic defects that might increase sulindac blood concentrations.
Glipizide; Metformin: (Moderate) NSAIDs may enhance hypoglycemia in diabetic patients via inhibition of prostaglandin synthesis, which indirectly increases insulin secretion. If NSAIDs are administered or discontinued in patients receiving oral antidiabetic agents, patients should be monitored for hypoglycemia or loss of blood glucose control. No clinically significant interaction between sulindac at daily doses of 400 mg and oral hypoglycemic agents has been observed. Sulindac, its sulfide metabolite, and sulfonylureas are highly bound to protein. Sulindac could displace the sulfonylureas, altering hypoglycemic activity. Careful patient monitoring is recommended to ensure that no change in their diabetes medicine dosage is required. A sulfonylurea dose adjustment may be needed, especially if sulindac doses greater than 400 mg daily are used or if the drug combination is used in patients with renal impairment or other metabolic defects that might increase sulindac blood concentrations.
Glucagon: (Moderate) When used with indomethacin, glucagon may lose its ability to raise blood glucose or may even produce hypoglycemia. Therefore, caution should be exercised for patients taking indomethacin when glucagon will be administered.
Glyburide: (Moderate) NSAIDs may enhance hypoglycemia in diabetic patients via inhibition of prostaglandin synthesis, which indirectly increases insulin secretion. If NSAIDs are administered or discontinued in patients receiving oral antidiabetic agents, patients should be monitored for hypoglycemia or loss of blood glucose control. No clinically significant interaction between sulindac at daily doses of 400 mg and oral hypoglycemic agents has been observed. Sulindac, its sulfide metabolite, and sulfonylureas are highly bound to protein. Sulindac could displace the sulfonylureas, altering hypoglycemic activity. Careful patient monitoring is recommended to ensure that no change in their diabetes medicine dosage is required. A sulfonylurea dose adjustment may be needed, especially if sulindac doses greater than 400 mg daily are used or if the drug combination is used in patients with renal impairment or other metabolic defects that might increase sulindac blood concentrations.
Glyburide; Metformin: (Moderate) NSAIDs may enhance hypoglycemia in diabetic patients via inhibition of prostaglandin synthesis, which indirectly increases insulin secretion. If NSAIDs are administered or discontinued in patients receiving oral antidiabetic agents, patients should be monitored for hypoglycemia or loss of blood glucose control. No clinically significant interaction between sulindac at daily doses of 400 mg and oral hypoglycemic agents has been observed. Sulindac, its sulfide metabolite, and sulfonylureas are highly bound to protein. Sulindac could displace the sulfonylureas, altering hypoglycemic activity. Careful patient monitoring is recommended to ensure that no change in their diabetes medicine dosage is required. A sulfonylurea dose adjustment may be needed, especially if sulindac doses greater than 400 mg daily are used or if the drug combination is used in patients with renal impairment or other metabolic defects that might increase sulindac blood concentrations.
Gold: (Moderate) Due to the inhibition of renal prostaglandins by NSAIDs, concurrent use with other nephrotoxic agents, such as gold compounds, may lead to additive nephrotoxicity. Monitor renal function carefully during concurrent therapy.
Guanabenz: (Moderate) NSAIDs may decrease the effect of antihypertensive agents through various mechanisms, including renal and peripheral vasoactive pathways.
Guanfacine: (Moderate) NSAIDs may decrease the effect of antihypertensive agents through various mechanisms, including renal and peripheral vasoactive pathways.
Haloperidol: (Minor) In a small study, during concomitant administration of haloperidol with indomethacin, adverse reactions, such as drowsiness and other effects, to haloperidol appeared to be intensified. Although more data are needed to confirm these findings, clinicians should administer indomethacin to patients stabilized on haloperidol cautiously. The effect of other NSAIDs on haloperidol are unknown.
Heparin: (Moderate) An additive risk of bleeding may be seen in patients receiving anticoagulants in combination with other agents known to increase the risk of bleeding such as nonsteroidal antiinflammatory drugs (NSAIDs). Monitor clinical and laboratory response closely during concurrent use.
Hyaluronidase, Recombinant; Immune Globulin: (Moderate) Immune Globulin (IG) products have been reported to be associated with renal dysfunction, acute renal failure, osmotic nephrosis, and death. Patients predisposed to acute renal failure include patients receiving known nephrotoxic drugs like nonsteroidal anti-inflammatory drugs (NSAIDs) and salicylates. Coadminister IG products at the minimum concentration available and the minimum rate of infusion practicable. Also, closely monitor renal function.
Hydrochlorothiazide, HCTZ; Methyldopa: (Moderate) If nonsteroidal anti-inflammatory drugs (NSAIDs) and an antihypertensive drug are concurrently used, carefully monitor the patient for signs and symptoms of renal insufficiency and blood pressure control. Doses of antihypertensive medications may require adjustment in patients receiving concurrent NSAIDs. NSAIDs, to varying degrees, have been associated with an elevation in blood pressure. This effect is most significant in patients receiving concurrent antihypertensive agents and long-term NSAID therapy. NSAIDs cause a dose-dependent reduction in prostaglandin formation, which may result in a reduction in renal blood flow leading to renal insufficiency and an increase in blood pressure that are often accompanied by peripheral edema and weight gain. Patients who rely upon renal prostaglandins to maintain renal perfusion may have acute renal blood flow reduction with NSAID usage. Elderly patients may be at increased risk of adverse effects from combined long-term NSAID therapy and antihypertensive agents, especially diuretics, due to age-related decreases in renal function and an increased risk of stroke and coronary artery disease.
Hydrochlorothiazide, HCTZ; Moexipril: (Moderate) Monitor blood pressure and renal function periodically during concomitant angiotensin-converting enzyme (ACE) inhibitor and nonsteroidal anti-inflammatory drug (NSAID) use. The antihypertensive effect of ACE inhibitors may be diminished by NSAIDs. In persons who are elderly, volume-depleted, or with compromised renal function, coadministration of ACE inhibitors and NSAIDs may result in deterioration of renal function, including possible acute renal failure; these effects are usually reversible.
Hydrocodone; Ibuprofen: (Major) Avoid concomitant use of ibuprofen with any other NSAID, including COX-2 inhibitors, due to the risk of additive serious NSAID toxicities including but not limited to GI bleeding, GI perforation, or peptic ulcers.
Hydrocortisone: (Moderate) Monitor for gastrointestinal toxicity during concurrent corticosteroid and nonsteroidal antiinflammatory drug (NSAID) use. Concomitant use increases the risk of GI bleeding. The Beers criteria recommends that this drug combination be avoided in older adults; if coadministration cannot be avoided, provide gastrointestinal protection.
Hyoscyamine; Methenamine; Methylene Blue; Phenyl Salicylate; Sodium Biphosphate: (Major) The concurrent use of salicylates and indomethacin is not recommended. Combined use does not produce any greater therapeutic effect than indomethacin monotherapy. Also, a significantly greater incidence of gastrointestinal adverse effects with concurrent use has been observed. Because NSAIDs can cause GI bleeding, inhibit platelet aggregation, and prolong bleeding time, additive effects may be seen in patients receiving platelet inhibitors (e.g., aspirin), anticoagulants, or thrombolytic agents.
Ibandronate: (Moderate) Monitor renal function and for gastrointestinal adverse events during concurrent use of intravenous or oral ibandronate, respectively, and nonsteroidal antiinflammatory drugs. Acute renal failure has been observed with intravenous ibandronate and concomitant use of other nephrotoxic agents may increase this risk. Additionally, the oral formulations of both medications have been associated with gastrointestinal irritation although data suggest concomitant use introduces little additional risk for adverse effects for most patients
Ibritumomab Tiuxetan: (Major) During and after therapy, avoid the concomitant use of Yttrium (Y)-90 ibrutumomab tiuxetan with drugs that interfere with platelet function such as nonsteroidal antiinflammatory drugs (NSAIDs); the risk of bleeding may be increased. If coadministration with NSAIDs is necessary, monitor platelet counts more frequently for evidence of thrombocytopenia.
Ibuprofen lysine: (Major) Because ibuprofen lysine exerts similar pharmacologic characteristics to other systemic NSAIDs, including COX-2 inhibitors, additive pharmacodynamic effects, including a potential increase for additive adverse GI effects, may be seen if ibuprofen lysine is used with other NSAIDs. In general, concurrent use of ibuprofen lysine and another NSAID should be avoided.
Ibuprofen: (Major) Avoid concomitant use of ibuprofen with any other NSAID, including COX-2 inhibitors, due to the risk of additive serious NSAID toxicities including but not limited to GI bleeding, GI perforation, or peptic ulcers.
Ibuprofen; Famotidine: (Major) Avoid concomitant use of ibuprofen with any other NSAID, including COX-2 inhibitors, due to the risk of additive serious NSAID toxicities including but not limited to GI bleeding, GI perforation, or peptic ulcers.
Ibuprofen; Oxycodone: (Major) Avoid concomitant use of ibuprofen with any other NSAID, including COX-2 inhibitors, due to the risk of additive serious NSAID toxicities including but not limited to GI bleeding, GI perforation, or peptic ulcers.
Ibuprofen; Pseudoephedrine: (Major) Avoid concomitant use of ibuprofen with any other NSAID, including COX-2 inhibitors, due to the risk of additive serious NSAID toxicities including but not limited to GI bleeding, GI perforation, or peptic ulcers.
Iloprost: (Moderate) If nonsteroidal anti-inflammatory drugs (NSAIDs) and an antihypertensive drug are concurrently used, carefully monitor the patient for signs and symptoms of renal insufficiency and blood pressure control. Doses of antihypertensive medications may require adjustment in patients receiving concurrent NSAIDs. NSAIDs, to varying degrees, have been associated with an elevation in blood pressure. This effect is most significant in patients receiving concurrent antihypertensive agents and long-term NSAID therapy. NSAIDs cause a dose-dependent reduction in prostaglandin formation, which may result in a reduction in renal blood flow leading to renal insufficiency and an increase in blood pressure that are often accompanied by peripheral edema and weight gain. Patients who rely upon renal prostaglandins to maintain renal perfusion may have acute renal blood flow reduction with NSAID usage. Elderly patients may be at increased risk of adverse effects from combined long-term NSAID therapy and antihypertensive agents, especially diuretics, due to age-related decreases in renal function and an increased risk of stroke and coronary artery disease.
Immune Globulin IV, IVIG, IGIV: (Moderate) Immune Globulin (IG) products have been reported to be associated with renal dysfunction, acute renal failure, osmotic nephrosis, and death. Patients predisposed to acute renal failure include patients receiving known nephrotoxic drugs like nonsteroidal anti-inflammatory drugs (NSAIDs) and salicylates. Coadminister IG products at the minimum concentration available and the minimum rate of infusion practicable. Also, closely monitor renal function.
Indapamide: (Moderate) Nonsteroidal anti-inflammatory drugs (NSAIDs) may reduce the natriuretic effect of diuretics in some patients. NSAIDS have been associated with an inhibition of prostaglandin synthesis, which may result in reduced renal blood flow leading to renal insufficiency and increases in blood pressure that are often accompanied by peripheral edema and weight gain. Patients taking diuretics and NSAIDS concurrently are at higher risk of developing renal insufficiency. If an NSAID and a diuretic are used concurrently, carefully monitor the patient for signs and symptoms of decreased renal function and diuretic efficacy.
Inotersen: (Moderate) Use caution with concomitant use of inotersen and nonsteroidal antiinflammatory drugs (NSAIDs) due to the risk of glomerulonephritis and nephrotoxicity as well as the potential risk of bleeding from thrombocytopenia. Consider discontinuation of NSAIDs in a patient taking inotersen with a platelet count of less than 50,000 per microliter.
Iodipamide Meglumine: (Moderate) Nonsteroidal anti-inflammatory drugs (NSAIDs) may increase the risk for nephrotoxicity when given to patients receiving a contrast agents. When possible, withhold NSAID therapy during administration of a contrast agent.
Iodixanol: (Moderate) Nonsteroidal anti-inflammatory drugs (NSAIDs) may increase the risk for nephrotoxicity when given to patients receiving a contrast agents. When possible, withhold NSAID therapy during administration of a contrast agent.
Iohexol: (Moderate) Nonsteroidal anti-inflammatory drugs (NSAIDs) may increase the risk for nephrotoxicity when given to patients receiving a contrast agents. When possible, withhold NSAID therapy during administration of a contrast agent.
Iomeprol: (Moderate) Nonsteroidal anti-inflammatory drugs (NSAIDs) may increase the risk for nephrotoxicity when given to patients receiving a contrast agents. When possible, withhold NSAID therapy during administration of a contrast agent.
Ionic Contrast Media: (Moderate) Nonsteroidal anti-inflammatory drugs (NSAIDs) may increase the risk for nephrotoxicity when given to patients receiving a contrast agents. When possible, withhold NSAID therapy during administration of a contrast agent.
Iopamidol: (Moderate) Nonsteroidal anti-inflammatory drugs (NSAIDs) may increase the risk for nephrotoxicity when given to patients receiving a contrast agents. When possible, withhold NSAID therapy during administration of a contrast agent.
Iopromide: (Moderate) Nonsteroidal anti-inflammatory drugs (NSAIDs) may increase the risk for nephrotoxicity when given to patients receiving a contrast agents. When possible, withhold NSAID therapy during administration of a contrast agent.
Ioversol: (Moderate) Nonsteroidal anti-inflammatory drugs (NSAIDs) may increase the risk for nephrotoxicity when given to patients receiving a contrast agents. When possible, withhold NSAID therapy during administration of a contrast agent.
Ioxaglate Meglumine; Ioxaglate Sodium: (Moderate) Nonsteroidal anti-inflammatory drugs (NSAIDs) may increase the risk for nephrotoxicity when given to patients receiving a contrast agents. When possible, withhold NSAID therapy during administration of a contrast agent.
Irbesartan: (Moderate) Monitor blood pressure and renal function periodically during concomitant angiotensin II blocker and nonsteroidal anti-inflammatory drug (NSAID) use. The antihypertensive effect of angiotensin II blockers may be diminished by NSAIDs. In persons who are elderly, volume-depleted, or with compromised renal function, coadministration of angiotensin II blockers and NSAIDs may result in deterioration of renal function, including possible acute renal failure; these effects are usually reversible.
Irbesartan; Hydrochlorothiazide, HCTZ: (Moderate) Monitor blood pressure and renal function periodically during concomitant angiotensin II blocker and nonsteroidal anti-inflammatory drug (NSAID) use. The antihypertensive effect of angiotensin II blockers may be diminished by NSAIDs. In persons who are elderly, volume-depleted, or with compromised renal function, coadministration of angiotensin II blockers and NSAIDs may result in deterioration of renal function, including possible acute renal failure; these effects are usually reversible.
Isosulfan Blue: (Moderate) Nonsteroidal anti-inflammatory drugs (NSAIDs) may increase the risk for nephrotoxicity when given to patients receiving a contrast agents. When possible, withhold NSAID therapy during administration of a contrast agent.
Ivacaftor: (Minor) Increased monitoring is recommended if ivacaftor is administered concurrently with CYP2C9 substrates, such as indomethacin. In vitro studies showed ivacaftor to be a weak inhibitor of CYP2C9. Co-administration may lead to increased exposure to CYP2C9 substrates; however, the clinical impact of this has not yet been determined.
Ketoprofen: (Major) Avoid concomitant use of indomethacin with any other NSAID, including COX-2 inhibitors, due to the risk of additive serious NSAID toxicities including but not limited to GI bleeding, GI perforation, or peptic ulcers.
Ketorolac: (Contraindicated) Concomitant use of ketorolac with another NSAID is contraindicated. Increased adverse gastrointestinal effects are possible if ketorolac is used with other systemic nonsteroidal antiinflammatory drugs (NSAIDs), including COX-2 inhibitors.
Labetalol: (Moderate) Monitor blood pressure during concomitant beta-blocker and nonsteroidal anti-inflammatory drug (NSAID) use. The antihypertensive effect of beta-blockers may be diminished by NSAIDs.
Lamivudine; Tenofovir Disoproxil Fumarate: (Moderate) Avoid administering tenofovir, PMPA concurrently with or recently after a nephrotoxic agent, such as high-dose or multiple nonsteroidal antiinflammatory drugs (NSAIDs). Cases of acute renal failure, some requiring hospitalization and renal replacement therapy, have been reported after high-dose or multiple NSAIDs were initiated in patients who appeared stable on tenofovir. Consider alternatives to NSAIDs in patients at risk for renal dysfunction. If these drugs must be coadministered, carefully monitor the estimated creatinine creatinine, serum phosphorus, urine glucose, and urine protein prior to, and periodically during, treatment.
Lansoprazole; Amoxicillin; Clarithromycin: (Minor) Indomethacin may compete with penicillin for renal tubular secretion, increasing penicillin serum concentrations. This combination should be used with caution and patients monitored for increased side effects.
Lansoprazole; Naproxen: (Major) Avoid concomitant use of indomethacin with any other NSAID, including COX-2 inhibitors, due to the risk of additive serious NSAID toxicities including but not limited to GI bleeding, GI perforation, or peptic ulcers.
Leflunomide: (Moderate) In vitro studies indicate that the M1 metabolite of leflunomide inhibits cytochrome P450 2C9, the enzyme responsible for the metabolism of many NSAIDs. Leflunomide altered protein binding and thus, increased the free fraction of ibuprofen by 13% to 50%. The clinical significance of the interactions with NSAIDs is unknown. There was extensive concomitant use of NSAIDs in phase III clinical studies of leflunomide in the treatment of rheumatoid arthritis, and no clinical differential effects were observed. However, because some NSAIDs have been reported to cause hepatotoxic effects, some caution may be warranted in their use with leflunomide.
Lepirudin: (Moderate) An additive risk of bleeding may be seen in patients receiving anticoagulants in combination with other agents known to increase the risk of bleeding such as nonsteroidal antiinflammatory drugs (NSAIDs). Monitor clinical and laboratory response closely during concurrent use.
Levobetaxolol: (Moderate) Monitor blood pressure during concomitant beta-blocker and nonsteroidal anti-inflammatory drug (NSAID) use. The antihypertensive effect of beta-blockers may be diminished by NSAIDs.
Levobunolol: (Moderate) Monitor blood pressure during concomitant beta-blocker and nonsteroidal anti-inflammatory drug (NSAID) use. The antihypertensive effect of beta-blockers may be diminished by NSAIDs.
Levomefolate: (Minor) L-methylfolate should be used cautiously in patients taking high doses of indomethacin. Plasma concentrations of L-methylfolate may be reduced when used concomitantly with high doses of indomethacin. Monitor patients for decreased efficacy of L-methylfolate if these agents are used together.
Levomilnacipran: (Moderate) Platelet aggregation may be impaired by SNRIs such as levomilnacipran due to platelet serotonin depletion, possibly increasing the risk of a bleeding complication (e.g., gastrointestinal bleeding, ecchymoses, epistaxis, hematomas, petechiae, hemorrhage) in patients receiving nonsteroidal antiinflammatory drugs (NSAIDs). Monitor for signs and symptoms of bleeding in patients taking levomilnacipran and NSAIDs.
Lisinopril: (Moderate) Monitor blood pressure and renal function periodically during concomitant angiotensin-converting enzyme (ACE) inhibitor and nonsteroidal anti-inflammatory drug (NSAID) use. The antihypertensive effect of ACE inhibitors may be diminished by NSAIDs. In persons who are elderly, volume-depleted, or with compromised renal function, coadministration of ACE inhibitors and NSAIDs may result in deterioration of renal function, including possible acute renal failure; these effects are usually reversible.
Lisinopril; Hydrochlorothiazide, HCTZ: (Moderate) Monitor blood pressure and renal function periodically during concomitant angiotensin-converting enzyme (ACE) inhibitor and nonsteroidal anti-inflammatory drug (NSAID) use. The antihypertensive effect of ACE inhibitors may be diminished by NSAIDs. In persons who are elderly, volume-depleted, or with compromised renal function, coadministration of ACE inhibitors and NSAIDs may result in deterioration of renal function, including possible acute renal failure; these effects are usually reversible.
Lithium: (Moderate) Monitor serum lithium concentrations during concomitant nonsteroidal anti-inflammatory (NSAID) use; reduce the lithium dose based on serum lithium concentrations and clinical response. NSAIDs decrease renal blood flow, resulting in decreased renal clearance and increased serum lithium concentrations.
Lomustine, CCNU: (Major) Due to the bone marrow suppressive and thrombocytopenic effects of lomustine, an additive risk of bleeding may be seen in patients receiving concomitant anticoagulants, NSAIDs, platelet inhibitors, including aspirin, ASA, strontium-89 chloride, and thrombolytic agents. In addition, large doses of salicylates (>= 3-4 g/day) can cause hypoprothrombinemia, an additional risk factor for bleeding.
Losartan: (Moderate) Monitor blood pressure and renal function periodically during concomitant angiotensin II blocker and nonsteroidal anti-inflammatory drug (NSAID) use. The antihypertensive effect of angiotensin II blockers may be diminished by NSAIDs. In persons who are elderly, volume-depleted, or with compromised renal function, coadministration of angiotensin II blockers and NSAIDs may result in deterioration of renal function, including possible acute renal failure; these effects are usually reversible.
Losartan; Hydrochlorothiazide, HCTZ: (Moderate) Monitor blood pressure and renal function periodically during concomitant angiotensin II blocker and nonsteroidal anti-inflammatory drug (NSAID) use. The antihypertensive effect of angiotensin II blockers may be diminished by NSAIDs. In persons who are elderly, volume-depleted, or with compromised renal function, coadministration of angiotensin II blockers and NSAIDs may result in deterioration of renal function, including possible acute renal failure; these effects are usually reversible.
Lumacaftor; Ivacaftor: (Minor) Although the clinical significance of this interaction is unknown, concurrent use of indomethacin and lumacaftor; ivacaftor may alter indomethacin exposure; caution and close monitoring are advised if these drugs are used together. Indomethacin is a substrate of CYP2C9. In vitro data suggest that lumacaftor; ivacaftor may induce and/or inhibit CYP2C9. The net effect of lumacaftor; ivacaftor on CYP2C9-mediated metabolism is not clear, but CYP2C9 substrate exposure may be affected leading to decreased efficacy or increased or prolonged therapeutic effects and adverse events.
Lumacaftor; Ivacaftor: (Minor) Increased monitoring is recommended if ivacaftor is administered concurrently with CYP2C9 substrates, such as indomethacin. In vitro studies showed ivacaftor to be a weak inhibitor of CYP2C9. Co-administration may lead to increased exposure to CYP2C9 substrates; however, the clinical impact of this has not yet been determined.
Macimorelin: (Major) Avoid use of macimorelin with drugs that directly affect pituitary growth hormone secretion, such as nonsteroidal antiinflammatory drugs (NSAIDs). Healthcare providers are advised to discontinue NSAID therapy and observe a sufficient washout period before administering macimorelin. Use of these medications together may impact the accuracy of the macimorelin growth hormone test.
Magnesium Salicylate: (Major) The concurrent use of salicylates and indomethacin is not recommended. Combined use does not produce any greater therapeutic effect than indomethacin monotherapy. Also, a significantly greater incidence of gastrointestinal adverse effects with concurrent use has been observed. Because NSAIDs can cause GI bleeding, inhibit platelet aggregation, and prolong bleeding time, additive effects may be seen in patients receiving platelet inhibitors (e.g., aspirin), anticoagulants, or thrombolytic agents.
Magnesium Sulfate; Potassium Sulfate; Sodium Sulfate: (Moderate) Use caution when prescribing sulfate salt bowel preparation in patients taking concomitant medications that may affect renal function such as nonsteroidal anti-inflammatory drugs (NSAIDs).
Mannitol: (Major) Avoid use of mannitol and nonsteroidal anti-inflammatory drugs (NSAIDs), if possible. If use together is necessary, carefully monitor the patient for signs and symptoms of decreased renal function and diuretic efficacy. Concomitant administration of nephrotoxic drugs, such as NSAIDs, increases the risk of renal failure after administration of mannitol. NSAIDs may reduce the natriuretic effect of diuretics in some patients. NSAIDS have been associated with an inhibition of prostaglandin synthesis, which may result in reduced renal blood flow leading to renal insufficiency and increases in blood pressure that are often accompanied by peripheral edema and weight gain.
Mecamylamine: (Moderate) If nonsteroidal anti-inflammatory drugs (NSAIDs) and an antihypertensive drug are concurrently used, carefully monitor the patient for signs and symptoms of renal insufficiency and blood pressure control. Doses of antihypertensive medications may require adjustment in patients receiving concurrent NSAIDs. NSAIDs, to varying degrees, have been associated with an elevation in blood pressure. This effect is most significant in patients receiving concurrent antihypertensive agents and long-term NSAID therapy. NSAIDs cause a dose-dependent reduction in prostaglandin formation, which may result in a reduction in renal blood flow leading to renal insufficiency and an increase in blood pressure that are often accompanied by peripheral edema and weight gain. Patients who rely upon renal prostaglandins to maintain renal perfusion may have acute renal blood flow reduction with NSAID usage. Elderly patients may be at increased risk of adverse effects from combined long-term NSAID therapy and antihypertensive agents, especially diuretics, due to age-related decreases in renal function and an increased risk of stroke and coronary artery disease.
Mechlorethamine, Nitrogen Mustard: (Major) Mechlorethamine, nitrogen mustard is highly toxic and is associated with lymphocytopenia, granulocytopenia, and thrombocytopenia. Due to the thrombocytopenic effects of mechlorethamine, an additive risk of bleeding may be seen in patients receiving concomitant anticoagulants, NSAIDs, platelet inhibitors, including aspirin, ASA, strontium-89 chloride, and thrombolytic agents. In addition, large doses of salicylates (>= 3-4 g/day) can cause hypoprothrombinemia, an additional risk factor for bleeding.
Meclofenamate Sodium: (Major) Avoid concomitant use of indomethacin with any other NSAID, including COX-2 inhibitors, due to the risk of additive serious NSAID toxicities including but not limited to GI bleeding, GI perforation, or peptic ulcers.
Mefenamic Acid: (Major) Avoid concomitant use of indomethacin with any other NSAID, including COX-2 inhibitors, due to the risk of additive serious NSAID toxicities including but not limited to GI bleeding, GI perforation, or peptic ulcers.
Meloxicam: (Major) Avoid concomitant use of indomethacin with any other NSAID, including COX-2 inhibitors, due to the risk of additive serious NSAID toxicities including but not limited to GI bleeding, GI perforation, or peptic ulcers.
Mesalamine, 5-ASA: (Minor) The concurrent use of mesalamine with known nephrotoxic agents such as nonsteroidal anti-inflammatory drugs (NSAIDs) may increase the risk of nephrotoxicity.
Methotrexate: (Major) Do not administer nonsteroidal anti-inflammatory drugs (NSAIDs) before or concomitantly with high doses of methotrexate, such as used in the treatment of osteosarcoma. Concomitant administration of some NSAIDs with high dose methotrexate therapy has been reported to elevate and prolong serum methotrexate concentrations, resulting in deaths from severe hematologic and gastrointestinal toxicity. Use caution when NSAIDs are administered concomitantly with lower doses of methotrexate as they have been reported to reduce the tubular secretion of methotrexate in an animal model and may enhance its toxicity. Despite potential interactions, patients with rheumatoid arthritis (RA) are often receiving concurrent treatment with NSAIDs without apparent problems. However, these doses are lower than those used in psoriasis or malignancy; higher methotrexate doses may lead to unexpected toxicity in combination with NSAIDs. NSAIDs may be continued in patients with RA receiving treatment with methotrexate, although the possibility of increased toxicity has not been fully explored.
Methoxsalen: (Major) Preclinical data suggest agents that inhibit prostaglandin synthesis such as indomethacin could decrease the efficacy of photosensitizing agents used in photodynamic therapy. Avoidance of indomethacin before and during photodynamic therapy may be advisable.
Methyldopa: (Moderate) If nonsteroidal anti-inflammatory drugs (NSAIDs) and an antihypertensive drug are concurrently used, carefully monitor the patient for signs and symptoms of renal insufficiency and blood pressure control. Doses of antihypertensive medications may require adjustment in patients receiving concurrent NSAIDs. NSAIDs, to varying degrees, have been associated with an elevation in blood pressure. This effect is most significant in patients receiving concurrent antihypertensive agents and long-term NSAID therapy. NSAIDs cause a dose-dependent reduction in prostaglandin formation, which may result in a reduction in renal blood flow leading to renal insufficiency and an increase in blood pressure that are often accompanied by peripheral edema and weight gain. Patients who rely upon renal prostaglandins to maintain renal perfusion may have acute renal blood flow reduction with NSAID usage. Elderly patients may be at increased risk of adverse effects from combined long-term NSAID therapy and antihypertensive agents, especially diuretics, due to age-related decreases in renal function and an increased risk of stroke and coronary artery disease.
Methylprednisolone: (Moderate) Monitor for gastrointestinal toxicity during concurrent corticosteroid and nonsteroidal antiinflammatory drug (NSAID) use. Concomitant use increases the risk of GI bleeding. The Beers criteria recommends that this drug combination be avoided in older adults; if coadministration cannot be avoided, provide gastrointestinal protection.
Methylsulfonylmethane, MSM: (Moderate) Patients taking methylsulfonylmethane, MSM have reported increased bruising or blood in the stool. These effects have not been confirmed in published medical literature or during clinical studies. Use methylsulfonylmethane, MSM with caution in patients who are taking drugs with the potential for additive bleeding, including nonsteroidal antiinflammatory drugs (NSAIDs). During an available, published clinical trials in patients with osteoarthritis, patients with bleeding disorders or using anticoagulants or platelet inhibiting drugs were excluded from enrollment.

Therefore, when mifepristone is used chronically, as in the treatment of Cushing's syndrome, use caution with coadministered CYP2C8/2C9 substrates, including the NSAIDs. Use the lowest doses of the substrate and patients should be monitored closely for adverse reactions.
Milnacipran: (Moderate) Platelet aggregation may be impaired by milnacipran due to platelet serotonin depletion, possibly increasing the risk of a bleeding complication (e.g., gastrointestinal bleeding, ecchymoses, epistaxis, hematomas, petechiae, hemorrhage) in patients receiving nonsteroidal antiinflammatory drugs (NSAIDs). Monitor for signs and symptoms of bleeding in patients taking milnacipran and NSAIDs.
Mitoxantrone: (Major) Due to the thrombocytopenic effects of mitoxantrone, an additive risk of bleeding may be seen in patients receiving concomitant anticoagulants, NSAIDs, platelet inhibitors, including aspirin, strontium-89 chloride, and thrombolytic agents. In addition, large doses of salicylates (>= 3-4 g/day) can cause hypoprothrombinemia, an additional risk factor for bleeding.

Neomycin: (Minor) It is possible that additive nephrotoxicity may occur in patients who receive NSAIDs concurrently with other nephrotoxic agents, such as aminoglycosides.
Neostigmine: (Moderate) NSAIDs may cause additive pharmacodynamic GI effects with cholinesterase inhibitors, leading to gastrointestinal intolerance. Patients receiving concurrent NSAIDs should be monitored closely for symptoms of active or occult gastrointestinal bleeding. While NSAIDs appear to suppress microglial activity, which in turn may slow inflammatory neurodegenerative processes important for the progression of Alzheimer's disease (AD), there are no clinical data at this time to suggest that NSAIDs alone or as combined therapy with AD agents result in synergistic effects in AD.
Non-Ionic Contrast Media: (Moderate) Nonsteroidal anti-inflammatory drugs (NSAIDs) may increase the risk for nephrotoxicity when given to patients receiving a contrast agents. When possible, withhold NSAID therapy during administration of a contrast agent.
Olanzapine; Fluoxetine: (Moderate) Monitor for signs and symptoms of bleeding during concomitant selective serotonin reuptake inhibitor (SSRI) and nonsteroidal antiinflammatory drug (NSAID) use due to increased risk for bleeding.

In persons who are elderly, volume-depleted, or with compromised renal function, coadministration of ACE inhibitors and NSAIDs may result in deterioration of renal function, including possible acute renal failure; these effects are usually reversible.
Phenoxybenzamine: (Moderate) If nonsteroidal anti-inflammatory drugs (NSAIDs) and an antihypertensive drug are concurrently used, carefully monitor the patient for signs and symptoms of renal insufficiency and blood pressure control. Doses of antihypertensive medications may require adjustment in patients receiving concurrent NSAIDs. NSAIDs, to varying degrees, have been associated with an elevation in blood pressure. This effect is most significant in patients receiving concurrent antihypertensive agents and long-term NSAID therapy. NSAIDs cause a dose-dependent reduction in prostaglandin formation, which may result in a reduction in renal blood flow leading to renal insufficiency and an increase in blood pressure that are often accompanied by peripheral edema and weight gain. Patients who rely upon renal prostaglandins to maintain renal perfusion may have acute renal blood flow reduction with NSAID usage. Elderly patients may be at increased risk of adverse effects from combined long-term NSAID therapy and antihypertensive agents, especially diuretics, due to age-related decreases in renal function and an increased risk of stroke and coronary artery disease.
Phentolamine: (Moderate) If nonsteroidal anti-inflammatory drugs (NSAIDs) and an antihypertensive drug are concurrently used, carefully monitor the patient for signs and symptoms of renal insufficiency and blood pressure control. Doses of antihypertensive medications may require adjustment in patients receiving concurrent NSAIDs. NSAIDs, to varying degrees, have been associated with an elevation in blood pressure. This effect is most significant in patients receiving concurrent antihypertensive agents and long-term NSAID therapy. NSAIDs cause a dose-dependent reduction in prostaglandin formation, which may result in a reduction in renal blood flow leading to renal insufficiency and an increase in blood pressure that are often accompanied by peripheral edema and weight gain. Patients who rely upon renal prostaglandins to maintain renal perfusion may have acute renal blood flow reduction with NSAID usage.

Photosensitizing agents (topical): (Moderate) Agents that inhibit prostaglandin synthesis such as nonsteroidal antiinflammatory drugs (NSAIDs), could decrease the efficacy of photosensitizing agents used in photodynamic therapy. Avoidance of NSAIDs before and during photodynamic therapy may be advisable.
Physostigmine: (Moderate) NSAIDs may cause additive pharmacodynamic GI effects with cholinesterase inhibitors, leading to gastrointestinal intolerance. Patients receiving concurrent NSAIDs should be monitored closely for symptoms of active or occult gastrointestinal bleeding. While NSAIDs appear to suppress microglial activity, which in turn may slow inflammatory neurodegenerative processes important for the progression of Alzheimer's disease (AD), there are no clinical data at this time to suggest that NSAIDs alone or as combined therapy with AD agents result in synergistic effects in AD.

Pioglitazone; Glimepiride: (Moderate) NSAIDs may enhance hypoglycemia in diabetic patients via inhibition of prostaglandin synthesis, which indirectly increases insulin secretion. If NSAIDs are administered or discontinued in patients receiving oral antidiabetic agents, patients should be monitored for hypoglycemia or loss of blood glucose control. No clinically significant interaction between sulindac at daily doses of 400 mg and oral hypoglycemic agents has been observed. Sulindac, its sulfide metabolite, and sulfonylureas are highly bound to protein. Sulindac could displace the sulfonylureas, altering hypoglycemic activity. Careful patient monitoring is recommended to ensure that no change in their diabetes medicine dosage is required. A sulfonylurea dose adjustment may be needed, especially if sulindac doses greater than 400 mg daily are used or if the drug combination is used in patients with renal impairment or other metabolic defects that might increase sulindac blood concentrations.
Piperacillin; Tazobactam: (Minor) Indomethacin may compete with penicillin for renal tubular secretion, increasing penicillin serum concentrations. This combination should be used with caution and patients monitored for increased side effects.

Platelet Inhibitors: (Moderate) Monitor for signs and symptoms of bleeding during concomitant platelet inhibitor and chronic nonsteroidal antiinflammatory drug (NSAID) use. Concomitant use increases the risk of bleeding.
Pneumococcal Vaccine, Polyvalent: (Moderate) Concomitant administration of antipyretics, such as nonsteroidal antiinflammatory drugs (NSAIDS), may decrease an individual's immunological response to the pneumococcal vaccine. A post-marketing study conducted in Poland using a non-US vaccination schedule (2, 3, 4, and 12 months of age) evaluated the impact of prophylactic oral acetaminophen on antibody responses to Prevnar 13. Data show that acetaminophen, given at the time of vaccination and then dosed at 6 to 8 hour intervals for 3 doses on a scheduled basis, reduced the antibody response to some serotypes after the third dose of Prevnar 13 when compared to the antibody responses of infants who only received antipyretics 'as needed' for treatment. However, reduced antibody responses were not observed after the fourth dose of Prevnar 13 with prophylactic acetaminophen.

Polymyxin B: (Major) The chronic coadministration of systemic polymyxins may increase the risk of developing nephrotoxicity, even in patients who have normal renal function. Nonsteroidal antiinflammatory drugs (NSAIDs) may increase the risk for nephrotoxicity when used concurrently. Monitor patients for changes in renal function if these drugs are coadministered. Since Polymyxin B is eliminated by the kidney, coadministration with other potentially nephrotoxic drugs, including nonsteroidal antiinflammatory drugs (NSAIDs), may theoretically increase serum concentrations of either drug.
Potassium: (Moderate) Monitor serum potassium concentrations closely if potassium supplements and nonsteroidal anti-inflammatory drugs (NSAIDs) are used together. Concomitant use may increase the risk of hyperkalemia.
Pralatrexate: (Major) Renal elimination accounts for approximately 34% of the overall clearance of pralatrexate. Concomitant administration of drugs that undergo substantial renal clearance, such as nonsteroidal antiinflammatory drugs (NSAIDs), may result in delayed clearance of pralatrexate.
Prasugrel: (Moderate) Monitor for signs and symptoms of bleeding during concomitant platelet inhibitor and chronic nonsteroidal antiinflammatory drug (NSAID) use. Concomitant use increases the risk of bleeding.
Prazosin: (Moderate) If nonsteroidal anti-inflammatory drugs (NSAIDs) and an antihypertensive drug are concurrently used, carefully monitor the patient for signs and symptoms of renal insufficiency and blood pressure control. Doses of antihypertensive medications may require adjustment in patients receiving concurrent NSAIDs. NSAIDs, to varying degrees, have been associated with an elevation in blood pressure. This effect is most significant in patients receiving concurrent antihypertensive agents and long-term NSAID therapy. NSAIDs cause a dose-dependent reduction in prostaglandin formation, which may result in a reduction in renal blood flow leading to renal insufficiency and an increase in blood pressure that are often accompanied by peripheral edema and weight gain. Patients who rely upon renal prostaglandins to maintain renal perfusion may have acute renal blood flow reduction with NSAID usage.

Elderly patients may be at increased risk of adverse effects from combined long-term NSAID therapy and antihypertensive agents, especially diuretics, due to age-related decreases in renal function and an increased risk of stroke and coronary artery disease.
Reteplase, r-PA: (Moderate) NSAIDs can cause GI bleeding, inhibit platelet aggregation, prolong bleeding time; these pharmacodynamic effects may be increased when administered to patients receiving thrombolytic agents. Patients receiving these drugs concurrently should be monitored closely for bleeding.
Risedronate: (Minor) Monitor for gastrointestinal adverse events during concurrent use of risedronate and nonsteroidal antiinflammatory drugs. Both medications have been associated with gastrointestinal irritation although data suggest concomitant use introduces little additional risk for adverse effects for most patients.

Telmisartan: (Moderate) Monitor blood pressure and renal function periodically during concomitant angiotensin II blocker and nonsteroidal anti-inflammatory drug (NSAID) use. The antihypertensive effect of angiotensin II blockers may be diminished by NSAIDs. In persons who are elderly, volume-depleted, or with compromised renal function, coadministration of angiotensin II blockers and NSAIDs may result in deterioration of renal function, including possible acute renal failure; these effects are usually reversible.
Telmisartan; Amlodipine: (Moderate) Monitor blood pressure and renal function periodically during concomitant angiotensin II blocker and nonsteroidal anti-inflammatory drug (NSAID) use. The antihypertensive effect of angiotensin II blockers may be diminished by NSAIDs. In persons who are elderly, volume-depleted, or with compromised renal function, coadministration of angiotensin II blockers and NSAIDs may result in deterioration of renal function, including possible acute renal failure; these effects are usually reversible.
Telmisartan; Hydrochlorothiazide, HCTZ: (Moderate) Monitor blood pressure and renal function periodically during concomitant angiotensin II blocker and nonsteroidal anti-inflammatory drug (NSAID) use. The antihypertensive effect of angiotensin II blockers may be diminished by NSAIDs. In persons who are elderly, volume-depleted, or with compromised renal function, coadministration of angiotensin II blockers and NSAIDs may result in deterioration of renal function, including possible acute renal failure; these effects are usually reversible.
Temozolomide: (Major) Myelosuppression, primarily neutropenia and thrombocytopenia, is the dose-limiting toxicity of temozolomide. Due to the thrombocytopenic effects of temozolomide, an additive risk of bleeding may be seen in patients receiving concomitant anticoagulants, NSAIDs, platelet inhibitors, including aspirin, ASA, strontium-89 chloride, and thrombolytic agents. In addition, large doses of salicylates (>= 3-4 g/day) can cause hypoprothrombinemia, an additional risk factor for bleeding.
Tenecteplase: (Moderate) NSAIDs can cause GI bleeding, inhibit platelet aggregation, prolong bleeding time; these pharmacodynamic effects may be increased when administered to patients receiving thrombolytic agents. Patients receiving these drugs concurrently should be monitored closely for bleeding.
Teniposide: (Major) Dose-limiting bone marrow suppression is the most significant toxicity associated with teniposide, and may include thrombocytopenia. An additive risk of bleeding may be seen in patients receiving concomitant NSAIDs. In addition, large doses of salicylates (>= 3-4 g/day) can cause hypoprothrombinemia, an additional risk factor for bleeding. Salicylates also displace protein-bound teniposide in fresh human serum to a small but significant extent. Because of the extremely high binding of teniposide to plasma proteins, these small decreases in binding could cause substantial increases in plasma free drug concentrations that could result in potentiation of teniposide toxicity, including bone marrow suppression.
Tenofovir Alafenamide: (Moderate) Monitor for changes in renal function if tenofovir alafenamide is administered in combination with nephrotoxic agents, such as nonsteroidal antiinflammatory drugs (NSAIDs). Tenofovir is primarily excreted via the kidneys by a combination of glomerular filtration and active tubular secretion. Coadministration of tenofovir alafenamide with a drug that reduces renal function or competes for active tubular secretion may increase concentrations of tenofovir and other renally eliminated drugs, thus, increasing the risk of adverse reactions.
Tenofovir Disoproxil Fumarate: (Moderate) Avoid administering tenofovir, PMPA concurrently with or recently after a nephrotoxic agent, such as high-dose or multiple nonsteroidal antiinflammatory drugs (NSAIDs). Cases of acute renal failure, some requiring hospitalization and renal replacement therapy, have been reported after high-dose or multiple NSAIDs were initiated in patients who appeared stable on tenofovir. Consider alternatives to NSAIDs in patients at risk for renal dysfunction. If these drugs must be coadministered, carefully monitor the estimated creatinine creatinine, serum phosphorus, urine glucose, and urine protein prior to, and periodically during, treatment.
Terazosin: (Moderate) If nonsteroidal anti-inflammatory drugs (NSAIDs) and an antihypertensive drug are concurrently used, carefully monitor the patient for signs and symptoms of renal insufficiency and blood pressure control. Doses of antihypertensive medications may require adjustment in patients receiving concurrent NSAIDs. NSAIDs, to varying degrees, have been associated with an elevation in blood pressure. This effect is most significant in patients receiving concurrent antihypertensive agents and long-term NSAID therapy. NSAIDs cause a dose-dependent reduction in prostaglandin formation, which may result in a reduction in renal blood flow leading to renal insufficiency and an increase in blood pressure that are often accompanied by peripheral edema and weight gain. Patients who rely upon renal prostaglandins to maintain renal perfusion may have acute renal blood flow reduction with NSAID usage. Elderly patients may be at increased risk of adverse effects from combined long-term NSAID therapy and antihypertensive agents, especially diuretics, due to age-related decreases in renal function and an increased risk of stroke and coronary artery disease.
Tezacaftor; Ivacaftor: (Minor) Increased monitoring is recommended if ivacaftor is administered concurrently with CYP2C9 substrates, such as indomethacin. In vitro studies showed ivacaftor to be a weak inhibitor of CYP2C9. Co-administration may lead to increased exposure to CYP2C9 substrates; however, the clinical impact of this has not yet been determined.
Thiazide diuretics: (Moderate) Monitor blood pressure as well as for signs of worsening renal function and loss of diuretic efficacy, including antihypertensive effects, during concomitant nonsteroidal antiinflammatory drug (NSAID) and thiazide diuretic use. NSAIDs may cause a dose-dependent reduction in renal blood flow, which may precipitate overt renal decompensation, and concomitant diuretic use increases the risk of this reaction. NSAIDs have been shown to reduce the natriuretic effect of thiazide diuretics and are associated with fluid retention which may blunt the cardiovascular effects of diuretics.
Thioguanine, 6-TG: (Major) Due to the thrombocytopenic effects of thioguanine, an additive risk of bleeding may be seen in patients receiving concomitant anticoagulants, NSAIDs, platelet inhibitors, including aspirin, strontium-89 chloride, and thrombolytic agents. In addition, large doses of salicylates (>= 3-4 g/day) can cause hypoprothrombinemia, an additional risk factor for bleeding.
Thrombolytic Agents: (Moderate) NSAIDs can cause GI bleeding, inhibit platelet aggregation, prolong bleeding time; these pharmacodynamic effects may be increased when administered to patients receiving thrombolytic agents. Patients receiving these drugs concurrently should be monitored closely for bleeding.
Ticagrelor: (Moderate) Monitor for signs and symptoms of bleeding during concomitant platelet inhibitor and chronic nonsteroidal antiinflammatory drug (NSAID) use. Concomitant use increases the risk of bleeding.
Ticlopidine: (Moderate) Monitor for signs and symptoms of bleeding during concomitant platelet inhibitor and chronic nonsteroidal antiinflammatory drug (NSAID) use. Concomitant use increases the risk of bleeding.
Timolol: (Moderate) Monitor blood pressure during concomitant beta-blocker and nonsteroidal anti-inflammatory drug (NSAID) use. The antihypertensive effect of beta-blockers may be diminished by NSAIDs.
Tirofiban: (Moderate) Monitor for signs and symptoms of bleeding during concomitant platelet inhibitor and chronic nonsteroidal antiinflammatory drug (NSAID) use. Concomitant use increases the risk of bleeding.
Tobacco: (Major) Advise patients to avoid smoking tobacco while taking nonsteroidal anti-inflammatory drugs (NSAIDs). Concomitant use of NSAIDs with tobacco smoking may enhance the risk of gastrointestinal side effects, including peptic ulcer and GI bleeding. Patients using tobacco and NSAIDs concurrently should be monitored closely for GI adverse reactions.
Tobramycin: (Moderate) It is possible that additive nephrotoxicity may occur in patients who receive nonsteroidal anti-inflammatory drugs (NSAIDs) concurrently with other nephrotoxic agents, such as tobramycin.
Tolazamide: (Moderate) NSAIDs may enhance hypoglycemia in diabetic patients via inhibition of prostaglandin synthesis, which indirectly increases insulin secretion. If NSAIDs are administered or discontinued in patients receiving oral antidiabetic agents, patients should be monitored for hypoglycemia or loss of blood glucose control. No clinically significant interaction between sulindac at daily doses of 400 mg and oral hypoglycemic agents has been observed. Sulindac, its sulfide metabolite, and sulfonylureas are highly bound to protein. Sulindac could displace the sulfonylureas, altering hypoglycemic activity. Careful patient monitoring is recommended to ensure that no change in their diabetes medicine dosage is required. A sulfonylurea dose adjustment may be needed, especially if sulindac doses greater than 400 mg daily are used or if the drug combination is used in patients with renal impairment or other metabolic defects that might increase sulindac blood concentrations.
Tolbutamide: (Moderate) NSAIDs may enhance hypoglycemia in diabetic patients via inhibition of prostaglandin synthesis, which indirectly increases insulin secretion. If NSAIDs are administered or discontinued in patients receiving oral antidiabetic agents, patients should be monitored for hypoglycemia or loss of blood glucose control. No clinically significant interaction between sulindac at daily doses of 400 mg and oral hypoglycemic agents has been observed. Sulindac, its sulfide metabolite, and sulfonylureas are highly bound to protein. Sulindac could displace the sulfonylureas, altering hypoglycemic activity. Careful patient monitoring is recommended to ensure that no change in their diabetes medicine dosage is required. A sulfonylurea dose adjustment may be needed, especially if sulindac doses greater than 400 mg daily are used or if the drug combination is used in patients with renal impairment or other metabolic defects that might increase sulindac blood concentrations.
Tolmetin: (Major) Avoid concomitant use of indomethacin with any other NSAID, including COX-2 inhibitors, due to the risk of additive serious NSAID toxicities including but not limited to GI bleeding, GI perforation, or peptic ulcers.
Torsemide: (Moderate) If a nonsteroidal anti-inflammatory drug (NSAID) and a diuretic are used concurrently, carefully monitor the patient for signs and symptoms of decreased renal function and diuretic efficacy. Patients taking diuretics and NSAIDs concurrently are at higher risk of developing renal insufficiency. NSAIDs may reduce the natriuretic effect of diuretics in some patients. NSAIDs have been associated with an inhibition of prostaglandin synthesis, which may result in reduced renal blood flow leading to renal insufficiency and increases in blood pressure that are often accompanied by peripheral edema and weight gain.
Tositumomab: (Major) The tositumomab therapeutic regimen frequently causes severe and prolonged thrombocytopenia. The potential benefits of medications that interfere with platelet function and/or anticoagulation should be weighed against the potential increased risk of bleeding and hemorrhage. An additive risk of bleeding may be seen in patients receiving concomitant NSAIDs. In addition, large doses of salicylates (>= 3-4 g/day) can cause hypoprothrombinemia, an additional risk factor for bleeding.
Trandolapril: (Moderate) Monitor blood pressure and renal function periodically during concomitant angiotensin-converting enzyme (ACE) inhibitor and nonsteroidal anti-inflammatory drug (NSAID) use. The antihypertensive effect of ACE inhibitors may be diminished by NSAIDs. In persons who are elderly, volume-depleted, or with compromised renal function, coadministration of ACE inhibitors and NSAIDs may result in deterioration of renal function, including possible acute renal failure; these effects are usually reversible.
Trandolapril; Verapamil: (Moderate) Monitor blood pressure and renal function periodically during concomitant angiotensin-converting enzyme (ACE) inhibitor and nonsteroidal anti-inflammatory drug (NSAID) use. The antihypertensive effect of ACE inhibitors may be diminished by NSAIDs. In persons who are elderly, volume-depleted, or with compromised renal function, coadministration of ACE inhibitors and NSAIDs may result in deterioration of renal function, including possible acute renal failure; these effects are usually reversible.
Trazodone: (Moderate) Platelet aggregation may be impaired by trazodone due to platelet serotonin depletion, possibly increasing the risk of a bleeding complication (e.g., gastrointestinal bleeding, ecchymoses, epistaxis, hematomas, petechiae, hemorrhage) in patients receiving nonsteroidal antiinflammatory drugs (NSAIDs). Patients should be instructed to monitor for signs and symptoms of bleeding while taking trazodone concurrently with medications that impair platelet function and to promptly report any bleeding events to the practitioner.
Treprostinil: (Moderate) NSAIDs may decrease the effect of antihypertensive agents through various mechanisms, including renal and peripheral vasoactive pathways.
Triamcinolone: (Moderate) Monitor for gastrointestinal toxicity during concurrent corticosteroid and nonsteroidal antiinflammatory drug (NSAID) use. Concomitant use increases the risk of GI bleeding. The Beers criteria recommends that this drug combination be avoided in older adults; if coadministration cannot be avoided, provide gastrointestinal protection.
Triamterene: (Major) Indomethacin and triamterene should not be given together; reversible acute renal failure occurred in 2 of 4 patients who had the addition of triamterene to their maintenance indomethacin regimen. Also, additive effects on serum potassium concentrations may occur with potassium-sparing diuretics and indomethacin usage. In addition, nonsteroidal anti-inflammatory drugs (NSAIDs) may reduce the natriuretic effect of diuretics in some patients. NSAIDS have been associated with an inhibition of prostaglandin synthesis, which may result in reduced renal blood flow leading to renal insufficiency and increases in blood pressure that are often accompanied by peripheral edema and weight gain. Patients taking diuretics and NSAIDS concurrently are at higher risk of developing renal insufficiency. If indomethacin and a diuretic are used concurrently, carefully monitor the patient for signs and symptoms of decreased renal function and diuretic efficacy.
Triamterene; Hydrochlorothiazide, HCTZ: (Major) Indomethacin and triamterene should not be given together; reversible acute renal failure occurred in 2 of 4 patients who had the addition of triamterene to their maintenance indomethacin regimen. Also, additive effects on serum potassium concentrations may occur with potassium-sparing diuretics and indomethacin usage. In addition, nonsteroidal anti-inflammatory drugs (NSAIDs) may reduce the natriuretic effect of diuretics in some patients. NSAIDS have been associated with an inhibition of prostaglandin synthesis, which may result in reduced renal blood flow leading to renal insufficiency and increases in blood pressure that are often accompanied by peripheral edema and weight gain. Patients taking diuretics and NSAIDS concurrently are at higher risk of developing renal insufficiency. If indomethacin and a diuretic are used concurrently, carefully monitor the patient for signs and symptoms of decreased renal function and diuretic efficacy.
Urea: (Moderate) Nonsteroidal anti-inflammatory drugs (NSAIDs) may reduce the natriuretic effect of diuretics in some patients. NSAIDS have been associated with an inhibition of prostaglandin synthesis, which may result in reduced renal blood flow leading to renal insufficiency and increases in blood pressure that are often accompanied by peripheral edema and weight gain. Patients taking diuretics and NSAIDS concurrently are at higher risk of developing renal insufficiency. If an NSAID and a diuretic are used concurrently, carefully monitor the patient for signs and symptoms of decreased renal function and diuretic efficacy.
Valacyclovir: (Moderate) Monitor patients for signs of worsening renal function during coadministration of valacyclovir and nonsteroidal antiinflammatory drugs. Coadministration may increase the risk for drug-induced nephrotoxicity.
Valganciclovir: (Minor) Concurrent use of nephrotoxic agents, such as NSAIDs, with valganciclovir should be done cautiously to avoid additive nephrotoxicity.
Valsartan: (Moderate) Monitor blood pressure and renal function periodically during concomitant angiotensin II blocker and nonsteroidal anti-inflammatory drug (NSAID) use. The antihypertensive effect of angiotensin II blockers may be diminished by NSAIDs. In persons who are elderly, volume-depleted, or with compromised renal function, coadministration of angiotensin II blockers and NSAIDs may result in deterioration of renal function, including possible acute renal failure; these effects are usually reversible.
Valsartan; Hydrochlorothiazide, HCTZ: (Moderate) Monitor blood pressure and renal function periodically during concomitant angiotensin II blocker and nonsteroidal anti-inflammatory drug (NSAID) use. The antihypertensive effect of angiotensin II blockers may be diminished by NSAIDs. In persons who are elderly, volume-depleted, or with compromised renal function, coadministration of angiotensin II blockers and NSAIDs may result in deterioration of renal function, including possible acute renal failure; these effects are usually reversible.
Vancomycin: (Minor) It is possible that additive nephrotoxicity may occur in patients who receive NSAIDs concurrently with other nephrotoxic agents, including vancomycin.
Vasopressin, ADH: (Moderate) Monitor hemodynamics and adjust the dose of vasopressin as needed when used concomitantly with indomethacin. Use together may prolong the effect of vasopressin on cardiac index and systemic vascular resistance. Indomethacin more than doubles the time to offset for vasopressin's effect on peripheral vascular resistance and cardiac output in healthy subjects.
Vemurafenib: (Major) Concomitant use of vemurafenib and indomethacin may result in increased indomethacin concentrations. Vemurafenib is a CYP2C9 inhibitor and indomethacin is a CYP2C9 substrate. Patients should be monitored for toxicity.
Venlafaxine: (Moderate) Platelet aggregation may be impaired by venlafaxine due to platelet serotonin depletion, possibly increasing the risk of a bleeding complication (e.g., gastrointestinal bleeding, ecchymoses, epistaxis, hematomas, petechiae, hemorrhage) in patients receiving nonsteroidal antiinflammatory drugs (NSAIDs). Monitor patients for signs and symptoms of bleeding when coadministering venlafaxine with NSAIDs.
Verteporfin: (Moderate) Use caution if coadministration of verteporfin with nonsteroidal anti-inflammatory drugs is necessary due to the risk of decreased verteporfin efficacy. Oxaprozin may additionally worsen photosensitivity. Verteporfin is a light-activated drug. Once activated, local damage to neovascular endothelium results in a release of procoagulant and vasoactive factors resulting in platelet aggregation, fibrin clot formation, and vasoconstriction. Concomitant use of drugs that decrease platelet aggregation like nonsteroidal anti-inflammatory drugs could decrease the efficacy of verteporfin therapy.
Vilazodone: (Moderate) Platelet aggregation may be impaired by vilazodone due to platelet serotonin depletion, possibly increasing the risk of a bleeding complication (e.g., gastrointestinal bleeding, ecchymoses, epistaxis, hematomas, petechiae, hemorrhage) in patients receiving nonsteroidal antiinflammatory drugs (NSAIDs). Patients should be instructed to monitor for signs and symptoms of bleeding while taking vilazodone concurrently with NSAIDs and to promptly report any bleeding events to the practitioner.
Voclosporin: (Moderate) Concomitant use of voclosporin and nonsteroidal anti-inflammatory drugs (NSAIDs) may result in additive nephrotoxicity. Monitor for renal toxicity if concomitant use is required.
Vonoprazan; Amoxicillin: (Minor) Indomethacin may compete with penicillin for renal tubular secretion, increasing penicillin serum concentrations. This combination should be used with caution and patients monitored for increased side effects.
Vonoprazan; Amoxicillin; Clarithromycin: (Minor) Indomethacin may compete with penicillin for renal tubular secretion, increasing penicillin serum concentrations. This combination should be used with caution and patients monitored for increased side effects.
Vorapaxar: (Moderate) Monitor for signs and symptoms of bleeding during concomitant platelet inhibitor and chronic nonsteroidal antiinflammatory drug (NSAID) use. Concomitant use increases the risk of bleeding.
Voriconazole: (Minor) Voriconazole is known to be an inhibitor of CYP2C9 and may lead to increased plasma levels of some NSAIDs, such as indomethacin. The clinical significance of this potential interaction is unknown. If voriconazole is used concurrently with indomethacin, monitor for NSAID-related side-effects, such as fluid retention or GI irritation, and adjust the dose of the NSAID if needed.
Vortioxetine: (Moderate) Platelet aggregation may be impaired by vortioxetine due to platelet serotonin depletion, possibly increasing the risk of a bleeding complication (e.g., gastrointestinal bleeding, ecchymoses, epistaxis, hematomas, petechiae, hemorrhage) in patients receiving nonsteroidal antiinflammatory drugs (NSAIDs). Bleeding events related to drugs that inhibit serotonin reuptake have ranged from ecchymosis to life-threatening hemorrhages. Patients should be instructed to monitor for signs and symptoms of bleeding while taking vortioxetine concurrently with medications which impair platelet function and to promptly report any bleeding events to the practitioner.
Warfarin: (Moderate) Monitor patients for signs or symptoms of bleeding during concurrent use of warfarin and nonsteroidal antiinflammatory drugs (NSAIDs).To minimize the potential for GI bleeding, use the lowest effective NSAID dose for the shortest possible duration. If signs or symptoms of bleeding occur, promptly evaluate and treat. Systemic hematological effects may also occur with the use of topical NSAIDs. NSAIDs inhibit platelet aggregation and may prolong bleeding time in some patients.
Zoledronic Acid: (Moderate) Monitor renal function during concomitant zoledronic acid and nonsteroidal antiinflammatory drug use due to risk for additive nephrotoxicity.
