1.    What Carbagen is and what it is used for

Carbagen is specially formulated to release the active ingredient gradually.

Carbamazepine, the active ingredient, can affect the body in several different ways. It is an anticonvulsant medicine (prevents fits), it can also modify some types of pain and can control mood disorders.

Carbagen is 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.

2.    What you need to know before you take Carbagen

A small number of people being treated with antiepileptics 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 influenzalike 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 have developed Stevens-Johnson syndrome or toxic epidermal necrolysis with the use of carbamazepine, you must not be re-started on carbamazepine at any time.

If you develop a rash or these skin symptoms, stop taking Carbagen, and contact your doctor immediately and tell them that you are taking this medicine.

Do not take Carbagen

•    if you are allergic to carbamazepine or similar medicines such as

oxcarbazepine, or to any of a related group of medicines 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,

•    if you are allergic to any of the other ingredients of Carbagen (listed in section 6),

•    if you have any heart problems,

•    if you have ever had problems with your bone marrow,

•    if you have or ever had blood disorders such as acute intermittent porphyria, variegate porphyria or porphyria cutanea tarda,

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

•    if you are taking voriconazole for a fungal infection,

•    if you are taking anything containing St. John's wort.

Carbagen with food, drink and alcohol

Do not take your tablets with grapefruit or grapefruit juice as this may increase the likelihood of side effects from Carbagen.

Pregnancy, breast-feeding and fertility If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine.

Pregnancy

Carbamazepine affects the way hormonal contraceptives work and there is a risk of getting pregnant. You should use other contraceptives. You must discuss your epilepsy treatment with your doctor well before you become pregnant. If you do get pregnant while taking Carbagen do not stop taking this medicine and tell the doctor straightaway. It is important that your epilepsy remains well controlled, but, as with other antiepilepsy treatments, there is a risk of harm to the baby. You should be able to have an antenatal scan to check for any problems. Make sure you are very clear about the risks and the benefits of taking Carbagen.

Breast-feeding

Mothers taking Carbagen can breast-feed 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 or skin reactions because you are taking Carbagen.

Fertility

Taking this medicine may affect male fertility. If you have any questions talk to your doctor.

Driving and using machines

Carbagen may make you feel dizzy or drowsy, 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 (blurred or double vision), you should not drive or operate machinery.

The tablet can be divided into equal doses.

If you take more Carbagen than you should

If you forget to take Carbagen

Take it as soon as you remember unless it is almost time for your next dose. Do not take a double dose to make up for a forgotten tablet.

If you stop taking Carbagen

Do not stop taking your tablets suddenly. Speak to your doctor first. If your dose needs to be reduced, this will be done slowly.
