1. what levetiracetam concentrate for solution for infusion is and what it is used for
Levetiracetam is an antiepileptic medicine (a medicine used to treat seizures in epilepsy).
Levetiracetam is used:
- on its own in adults and adolescents from 16 years of age with newly diagnosed epilepsy, to treat a certain form of epilepsy. Epilepsy is a condition where the patients have repeated fits (seizures). Levetiracetam is used for the epilepsy form in which the fits initially affect only one side of the brain, but could thereafter extend to larger areas on both sides of the brain (partial onset seizure with or without secondary generalisation). Levetiracetam has been given to you by your doctor to reduce the number of fits.
- as an add-on to other antiepileptic medicines to treat:
- partial onset seizures with or without generalisation in adults, adolescents and children from 4 years of age
- myoclonic seizures (short, shock-like jerks of a muscle or group of muscles) in adults and adolescents from 12 years of age with juvenile myoclonic epilepsy.
- primary generalised tonic-clonic seizures (major fits, including loss of consciousness) in adults and adolescents from 12 years of age with idiopathic generalised epilepsy (the type of epilepsy that is thought to have a genetic cause).
Levetiracetam concentrate for solution for infusion is an alternative for patients when administration of the antiepileptic oral Levetiracetam medicine is temporarily not feasible.
2. what you need to know before you are given levetiracetam concentrate for solution for infusion
