FDA Warnings

LEVETIRACETAM ORAL

5 WARNINGS AND PRECAUTIONS • Behavioral abnormalities including psychotic symptoms, suicidal ideation, irritability, and aggressive behavior have been observed; monitor patients for psychiatric signs and symptoms ( 5
3 ) • Serious Dermatological Reactions: Discontinue levetiracetam at the first sign of rash unless clearly not drug related (5
2 Suicidal Behavior and Ideation Antiepileptic drugs (AEDs), including levetiracetam, increase the risk of suicidal thoughts or behavior in patients taking these drugs for any indication
Pooled analyses of 199 placebo-controlled clinical trials (mono- and adjunctive therapy) of 11 different AEDs showed that patients randomized to one of the AEDs had approximately twice the risk (adjusted Relative Risk 1

VIGABATRIN

5 WARNINGS AND PRECAUTIONS Abnormal MRI signal changes and intramyelinic edema have been reported in some infants with Infantile Spasms receiving vigabatrin ( 5
4 ) Suicidal behavior and ideation: Antiepileptic drugs, including VIGADRONE, increase the risk of suicidal thoughts and behavior ( 5
Because of this risk and because, when it is effective, VIGADRONE provides an observable symptomatic benefit; patient response and continued need for treatment should be periodically assessed
For this reason, the understanding of the risk is primarily based on the adult experience
