Update 5/5/2009: 

AED class label changes

Manufacturers of antiepileptic drugs (AEDs) or anticonvulsant drugs will update product labeling to include a warning about an increased risk of suicidal thoughts or actions and will develop a Medication Guide to help patients understand this risk.  These changes affect all approved AEDs except those indicated only for short-term use.

Drugs with updated labels

The approved AEDs affected by these safety label changes are Carbatrol, Celontin, Depakene, Depakote ER, Depakote sprinkles, Depakote tablets, Dilantin, Equetro, Felbatol, Gabitril, Keppra, Keppra XR, Klonopin, Lamictal, Lyrica, Mysoline, Neurontin, Peganone, Stavzor, Tegretol, Tegretol XR, Topamax, Tranxene, Tridione, Trileptal, Zarontin, Zonegran, and generics.  FDA approved updated labeling for these drugs on April 23, 2009.  

Drugs with Medication Guides

New comprehensive Medication Guides were approved on April 23, 2009, for Lamictal, Lyrica, Topamax, Zonegran and Keppra.  Comprehensive Medication Guides are being developed for the other drugs and should be available by the end of 2009. 

Advice for healthcare professionals

Epilepsy and other illnesses for which antiepileptic drugs are prescribed are associated with an increased risk of suicidal thoughts and behavior.  If suicidal thoughts or behavior emerge during treatment with AEDs, the prescriber should consider whether these symptoms may be related to the illness being treated.

All patients who currently are 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.  

Background

Since issuing safety alerts on December 16, 2008 and January 31, 2008 (see below), FDA has been working with the manufacturers of drugs in this class to better understand the suicidality risk. 

As described in the January 31, 2008, Information for Health Care Professionals Sheet on AEDS, eleven antiepileptic drugs were included in FDA’s original pooled analysis of placebo-controlled clinical studies in which these drugs were used to treat epilepsy as well as psychiatric disorders and other conditions. 

The increased risk of suicidal thoughts or behavior was generally consistent among the eleven drugs, with varying mechanisms of action and across a range of indications.  This observation suggests that the risk applies to all antiepileptic drugs used for any indication.
