1) What Epanutin Capsules are and what they are used for
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
Do not take Epanutin Capsules
• if you are allergic to Phenytoin, or any of the other ingredients of this
medicine (listed in section 6).
• if you are allergic to other medicines with a similar chemical structure to
Phenytoin (e.g. hydantoins).
Warnings and precautions
Talk to your doctor or pharmacist before taking 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.
• Kidney disease.
• Porphyria (an inherited disease that affects haemoglobin biosynthesis).
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. If you are of such origin and have been tested
previously carrying this genetic variant (HLA-B*1502), discuss this with your
doctor before taking Epanutin Capsules.
Other medicines and Epanutin Capsules
Tell your doctor or pharmacist if you are taking, have recently taken or might
take any other medicines.

medicines taken at the same time. These include:

digoxin, furosemide, reserpine, warfarin, calcium channel blockers e.g.

consult your doctor before stopping the St John’s Wort preparation.

may be given.

Epanutin Capsules can be taken before or after food and drinks. Drinking a
lot of alcohol can also affect the concentration of Phenytoin in your blood.
Pregnancy and breast-feeding
If you are pregnant or breast-feeding, think you might be pregnant or are
planning to have a baby, ask your doctor or pharmacist for advice before
taking this medicine. If you find out you are pregnant, then you should
continue to take your medicine until you have spoken to your doctor for
advice. This is because Phenytoin should only be used during pregnancy,
especially early pregnancy, under the advice of your doctor because it can
be harmful to unborn children when taken by a woman during pregnancy. Do
not stop taking your medicine until your doctor tells you to.
You should not take Epanutin Capsules if you are breast-feeding.
