Keppra can also be used as adjunctive therapy in patients who already receive other anti-epileptic medicines to treat: • partial onset seizures with or without generalisation in patients from four years of age, • myoclonic seizures (short, shock-like jerks of a muscle or group of muscles) in patients from 12 years of age with juvenile myoclonic epilepsy, • primary generalised tonic-clonic seizures (major fits, including loss of consciousness) in patients from 12 years of age with idiopathic generalised epilepsy (the type of epilepsy that is thought to have a genetic cause).
