• Concurrently with other antiepileptic medications to treat:

-Partial onset seizures with or without generalization in adults, adolescents, children, and infants 1 month of age or older.

-Myoclonic seizures(shock-like, short, muscle or group of muscle seizures)in adults and adolescents 12 years of age or older with juvenile myoclonic epilepsy.

-Primary generalized tonic-clonic seizures (major seizures, including loss of consciousness) in adults and adolescents 12 years of age or older with idiopathic generalized epilepsy (a type of epilepsy thought to have a genetic cause).
