Tegretol Prolonged Release Tablets are specially formulated to release the active ingredient gradually. Carbamazepine, the active ingredient, can affect the body in several different ways. It is an anti-convulsant medicine (prevents fits), it can also modify some types of pain and can control mood disorders.

Tegretol Prolonged Release Tablets are used

•    To treat some forms of epilepsy

•    To treat a painful condition of the face called trigeminal neuralgia

•    To help control serious mood disorders when some other medicines don't work.

Some people MUST NOT take Tegretol Prolonged Release

Tablets. Talk to your doctor if:

•    you think you may be hypersensitive (allergic) to carbamazepine or similar drugs such as oxcarbazepine (Trileptal), or to any of a related group of drugs known as tricyclic antidepressants (such as amitriptyline or imipramine). If you are allergic to carbamazepine there is a one in four (25%) chance that you could also have an allergic reaction to oxcarbazepine.

•    you think you may be allergic to any of the other ingredients of Tegretol Prolonged Release Tablets (these are listed at the end of the leaflet). Signs of a hypersensitivity reaction include swelling of the face or mouth (angioedema), breathing problems, runny nose, skin rash, blistering or peeling.

•    you have any heart problems,

•    you have ever had problems with your bone marrow,

•    you have a blood disorder called porphyria,

•    you have taken drugs called monoamine oxidase inhibitors (MAOIs), used to treat depression, within the last 14 days.

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

Serious skin rashes (Stevens- Johnson syndrome, toxic epidermal necrolysis) have been reported with the use of carbamazepine. Frequently, the rash can involve ulcers of the mouth, throat, nose, genitals and conjunctivitis (red and swollen eyes). These serious skin rashes are often preceded by influenza-like symptoms fever, headache, body ache (flu-like symptoms). The rash may progress to widespread blistering and peeling of the skin. The highest risk for occurrence of serious skin reactions is within the first months of treatment.

These serious skin reactions can be more common in people from some Asian countries. The risk of these reactions in patients of Han Chinese or Thai origin may be predicted by testing a blood sample of these patients. Your doctor should be able to advise if a blood test is necessary before taking carbamazepine.

If you develop a rash or these skin symptoms, stop taking carbamazepine and contact your doctor immediately.

You should also ask yourself these questions before taking Tegretol Prolonged Release Tablets. If the answer to any of these questions is YES, discuss your treatment with your doctor or pharmacist because Tegretol Prolonged Release Tablets might not be the right medicine for you.

Pregnancy and breastfeeding

You must discuss your epilepsy treatment with your doctor well before you become pregnant. If you do get pregnant while you're taking Tegretol Prolonged Release Tablets you must tell the doctor straightaway. It is important that your epilepsy remains well controlled, but, as with other anti-epilepsy treatments, there is a risk of harm to the foetus. Make sure you are very clear about the risks and the benefits of taking Tegretol Prolonged Release Tablets.

Mothers taking Tegretol Prolonged Release Tablets can breastfeed their babies, but you must tell the doctor as soon as possible if you think that the baby is suffering side effects such as excessive sleepiness, skin reaction or yellow skin and eyes, dark urine or pale stools.

Tegretol Prolonged Release Tablets can make you feel dizzy or drowsy, or may cause blurred vision, double vision, or you may have a lack of muscular coordination, especially at the start of treatment or when the dose is changed. If you are affected in this way, or if your eyesight is affected, you should not drive or operate machinery.

Other special warnings

•    Drinking alcohol may affect you more than usual. Discuss whether you should stop drinking with your doctor.

•    Eating grapefruit, or drinking grapefruit juice, may increase your chance of experiencing side effects.

•    Your doctor may want you to have a number of blood tests before you start taking Tegretol and from time to time during your treatment. This is quite usual and nothing to worry about.
