Levetiracetam is also used in combination with other medications to treat seizure in adults and children 12 years of age or older with juvenile myoclonic epilepsy. Levetiracetam is also used in combination with other medications to treat primary generalized tonic-clonic seizures (formerly known as a grand mal seizure; seizure that involves the entire body) in adults and children 6 years of age or older with epilepsy. Levetiracetam is in a class of medications called anticonvulsants. It works by decreasing abnormal excitement in the brain.
