Psychiatric and behavioral concerns of perampanel with concomitant levetiracetam in children with epilepsy

Perampanel (PER) is expanding the therapeutic scope for pediatric epilepsy owing to its efficacy and favorable safety profile. However, concerns about psychiatric and behavioral adverse events (PBAEs) in combination therapy with levetiracetam (LEV) continue to contribute to hesitation in its prescription. We investigated the risk profiles for PBAEs when adding PER to pediatric epilepsy treatment and analyzed the differences according to the presence of concomitant LEV.
