    Somnolence and asthenia occurred most frequently within first 4 weeks of treatment; patients should be monitored for signs and symptoms and advised not to drive or operate machinery until they have gained sufficient experience on levetiracetam to gauge whether it adversely affects ability to drive or operate machinery

    As with most antiepileptic drugs, drug should generally be withdrawn gradually because of risk of increased seizure frequency and status epilepticus; if withdrawal needed because of serious adverse reaction, rapid discontinuation can be considered

    Psychiatric reactions: 13.3% of adults and 37.6% of children treated with levetiracetam reported nonpsychotic behavioral symptoms (eg, aggression, agitation, anger, anxiety, apathy, depersonalization, lability, hostility, hyperkinesis, irritability, nervousness, neurosis, and personality disorder) compared to 6.2% and 18.6% of adult and pediatric placebo patients respectively; dose reduction or discontinuation may be required

    Monitor patients for behavioral abnormalities including psychotic symptoms, suicidal ideation, irritability, aggressive behavior, and for new or worsening depression, suicidal thoughts/behavior, and/or unusual changes in mood or behavior

    Serious dermatological reactions, including Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) reported; median time of onset is reported to be 14-17 days; if signs or symptoms suggest SJS/TEN, use of this drug should not be resumed and alternative therapy should be considered

    Drug rash with eosinophilia and systemic syndrome (DRESS) reported

    May impair ability to operate heavy machinery

    There are no adequate and well-controlled studies in pregnant women; prolonged experience in pregnant women has not identified a drug-associated risk of major birth defects or miscarriage, based on published literature, which includes data from pregnancy registries, and reflects experience over two decades
