What Epanutin is and what it is used for

Epanutin is one of a group of medicines called anti-epileptic drugs; these
medicines are used to treat epilepsy.
Epanutin 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
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.

Before you take Epanutin

Do not take Epanutin
* if you are allergic (hypersensitive) to Phenytoin, or any of the other
ingredients of Epanutin Capsules.
Take special care with Epanutin
Medicines are not always suitable for everyone. Your doctor needs to know
before you take Epanutin if you suffer from or have suffered in the past from
any of the following conditions:
* Liver disease.
* Porphyria (an inherited disease that affects haemoglobin biosynthesis).

The herbal preparation St John’s wort (Hypericum perforatum) should not be
taken at the same time as this medicine. If you already take St John’s wort,
consult your doctor before stopping the St John’s wort preparation.
Epanutin capsules may also interfere with certain laboratory tests that you
may be given.
Taking Epanutin with food and drink
Epanutin 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 think you might be pregnant, or are planning to get pregnant, tell your
doctor before you take Epanutin
You should not take Epanutin if you are breast-feeding.
Ask your doctor or pharmacist for advice before taking any medicine.

weeks of treatment. If you experience these symptoms, do not drive or use
any tools or machinery.

How to take Epanutin

It is best to take Epanutin at the same time each day.
Swallow the capsules whole, with plenty of water.

A small number of people being treated with anti-epileptics such as
phenytoin sodium have had thoughts of harming or killing themselves.
If at any time you have these thoughts, immediately contact your doctor.

Adults
The amount of Epanutin needed varies from one person to another. Most
adults need between 200mg and 500mg a day either as a single or divided
dose. Occasionally higher doses are needed.

Serious skin side effects can rarely occur during treatment with Epanutin.
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.

Children
Infants and children usually start on a dose that depends on their weight
(5mg per day for every kg they weigh) and is given as a divided dose, twice
a day. The dose is then adjusted up to a maximum of 300mg a day.

Taking other medicines
Some medicines can affect the way Epanutin works, or Epanutin itself
can reduce the effectiveness of other medicines taken at the same
time. These include:
* Medicines used for heart and circulation problems (dicoumarol, digitoxin,
amiodarone, furosemide, quinidine, reserpine, warfarin, and calcium
channel blockers e.g. diltiazem and nifedipine).
* Medicines used for epilepsy (carbamazepine, lamotrigine, phenobarbital,
sodium valproate and valproic acid, succinimides e.g. ethosuximide and
vigabatrin).
* Medicines used to treat fungal infections (e.g. amphotericin B,
fluconazole, itraconazole, ketoconazole and miconazole).
* Medicines used for tuberculosis and other infections (chloramphenicol,
isoniazid, rifampicin, sulphonamides, doxycycline and ciprofloxacin) and
nelfinavir).
* Medicines used for stomach ulcers (omeprazole, sucralfate, the medicines
known as H2 antagonists e.g. cimetidine, ranitidine, famotidine and some
antacids).
* Medicines used for asthma and bronchitis (theophylline).
* Medicines used for pain and inflammation (phenylbutazone, salicylates
e.g. aspirin and steroids).
* Medicines used for sleeplessness, depression and psychiatric disorders
(chlordiazepoxide, clozapine, diazepam, disulfiram, fluoxetine,
methylphenidate, paroxetine, phenothiazines, trazodone, tricyclic
antidepressants fluvoxamine, sertraline and viloxazine).

Elderly
The dose of Epanutin for elderly patients who may be taking other medicines
may also need careful consideration and adjustment by their doctor.
Always take Epanutin exactly as your doctor has told you. You should check
with your doctor or pharmacist if you are still not sure.
If you take more Epanutin than you should
Epanutin is dangerous in overdose. If you accidentally take too much
Epanutin contact your doctor at once or go to the nearest hospital casualty
department. Always take the labelled medicine package with you, whether
there is any Epanutin left or not.
If you forget to take Epanutin
If you forget to take a dose, take it as soon as you remember unless it is
time for your next dose. Do not take a double dose to make up for a
missed dose.
If you stop taking Epanutin
Do not stop taking Epanutin unless your doctor tells you to. If you suddenly
stop taking this medicine you may have a seizure. Should you need to stop
taking Epanutin, your doctor will have decided which the best method is for
you.
If you have any further questions on how to take this Epanutin, ask your
doctor or pharmacist.

symptoms can be serious.
