Contents of the pack
Ontozry contains the active substance cenobamate. It belongs to a group of medicines called “antiepileptics”. These medicines are used to treat epilepsy, a condition that causes seizures or epileptic fits due to abnormal activity in the brain.
Ontozry is used in combination with other antiepileptic medicines in adult patients with epilepsy who have not achieved sufficient control despite treatment with at least 2 antiepileptics, to treat a type of epilepsy that causes focal onset seizures, with or without secondary generalization. Focal onset seizures are caused by abnormal brain activity that starts in one part of the brain, and secondary generalization means that this abnormal activity spreads to both sides of the brain. This medicine can only be used in adults.
