Your doctor may have prescribed it to help control your condition in addition to current medicines that you are taking. Your doctor may also have prescribed it for another reason.

There is no evidence that this medicine is addictive.

This medicine is available only with a doctor's prescription.

  • 3 years to control epilepsy

The dose varies from person to person.
