Levetiracetam-induced aggression and acute behavioral changes: A case report and literature review.

Levetiracetam is a second-generation antiepileptic medication used to treat a wide range of partial and generalized seizure disorders. While Levetiracetam is generally well-tolerated, mild mood-related side effects (e.g., anxiety, agitation, and depression) have been observed in a minority of patients in the days following initiation of therapy or changes in dosing. The development of acute aggression requiring termination of Levetiracetam therapy has been rarely reported in the medical literature but poses a limiting effect on treatment options for refractory epilepsy in pediatric patients. In this report, we present a teenage male patient with a history of seizure disorder who developed sudden, severe behavioral abnormalities and aggression following increases in his Levetiracetam dosing. His symptoms resolved rapidly after return of his medication dosing to baseline, with no further sequelae noted. Our observations suggest that Levetiracetam remains a safe and effective first-line antiepileptic whose adverse behavioral side effect profile can be properly managed with close patient monitoring and dose titration.
