1. WHAT EPANUTIN CAPSULES ARE AND WHAT THEY ARE USED FOI
Epanutin Capsules are one of a group of medicines called anti-epileptic drugs; these medicines are used to treat epilepsy.
Epanutin Capsules can be used to control a variety of epileptic conditions, to control or prevent seizures during or after brain surgery or severe head injury. Epanutin Capsules can also be used to treat trigeminal neuralgia (facial nerve pain).
You should ask your doctor if you are unsure why you have been given Epanutin Capsules.
2. WHAT YOU NEED TO KNOW BEFORE YOU TAKE EPANUTIN CAPSULES

Medicines are not always suitable for everyone. Your doctor needs to know before you take Epanutin Capsules if you suffer from or have suffered in the past from any of the following conditions:
• Liver disease.

A small number of people being treated with antiepileptics such as phenytoin sodium have had thoughts of harming or killing themselves. If at any time you have these thoughts, immediately contact your doctor.
Serious skin side effects can rarely occur during treatment with Epanutin Capsules. This risk may be associated with a variant in genes in a subject with Chinese or Thai origin.
