The FDA has completed its analysis of reports of suicidality (suicidal behavior or ideation [thoughts]) from placebo-controlled clinical trials of drugs used to treat epilepsy, psychiatric disorders, and other conditions. Based on the outcome of this review, FDA is requiring that all manufacturers of drugs in this class include a Warning in their labeling and develop a Medication Guide to be provided to patients prescribed these drugs to inform them of the risks of suicidal thoughts or actions.
All patients who are currently taking or starting on any antiepileptic drug for any indication should be monitored for notable changes in behavior that could indicate the emergence or worsening of suicidal thoughts or behavior or depression.
The following is a list of antiepileptic drugs* included in the FDA analyses that led to this labeling revision:
Carbamazepine (marketed as Carbatrol, Equetro, Tegretol, Tegretol XR)
Divalproex sodium (marketed as Depakote, Depakote ER)
Felbamate (marketed as Felbatol)
Gabapentin (marketed as Neurontin)
