Levetiracetam is an anticonvulsant medication primarily used to treat epilepsy. It is often prescribed to manage partial-onset seizures, myoclonic seizures, and primary generalized tonic-clonic seizures. Levetiracetam works by stabilizing electrical activity in the brain, helping to prevent seizure episodes. It is commonly used as an adjunctive therapy in patients who have not achieved adequate control with other antiepileptic medications.
