What Tegretol is used for
Tegretol has several uses:
to control epilepsy, a condition in which there are repeated seizures (fits). There
are many different
types of seizures, ranging from mild to severe.
to control sudden, repeated attacks of facial pain, known as trigeminal neuralgia
to control mania, a mental condition with episodes of overactivity, elation or irritability
to control bipolar mood disorder where periods of mania alternate with periods of
Tegretol belongs to a group of medicines called anticonvulsants.
These medicines are thought to work by regulating the way messages in the brain are
passed on by nerves so that seizures do not happen. Tegretol also regulates other
nerve functions in the body.
Tegretol may be used alone or in combination with other medicines to treat your condition.
Ask your doctor if you have any questions about why this medicine has been prescribed
Your doctor may have prescribed it for another purpose.
Tegretol is only available with a doctor's prescription. There is no evidence that

Before you take Tegretol
When you must not take it
Do not take Tegretol if you have an allergy to:
carbamazepine (the active ingredient of Tegretol) or any of the other ingredients
of Tegretol listed at the end of this leaflet
any other medicine containing carbamazepine
tricyclic antidepressants, which are medicines use to treat depression
Tell your doctor if you are allergic to oxcarbazepine, the active ingredient in Trileptal,
or to phenytoin. These two medicines are also used to treat epilepsy.
Some people who are allergic to oxcarbazepine or phenytoin are also allergic to Tegretol.
Some of the symptoms of an allergic reaction may include shortness of breath, wheezing
or difficulty breathing; swelling of the face, lips, tongue or other parts of the
body; rash, itching or hives on the skin.
Do not take Tegretol if you are taking a medicine called a monoamine oxidase inhibitor
(MAOI) or have been taking it within the past 14 days.
Taking this medicine with a MAOI, or within 14 days of taking a MAOI, may cause a
serious reaction with a sudden increase in body temperature, extremely high blood
pressure and severe convulsions.
Do not take Tegretol if you have, or have had, any of the following conditions:
severe liver or heart disease
a disease of the blood
an irregular heartbeat caused by a condition called A-V block
systemic lupus erythematosus, also called SLE
hepatic porphyria, a disturbance in the production of porphyrin, a pigment important
for liver function and blood formation
If you are not sure whether any of the above conditions apply to you, ask your doctor.
Do not take Tegretol after the expiry date printed on the pack or if the packaging
is torn or shows signs of tampering.
In that case, return it to your pharmacist.
If you are not sure whether you should start taking Tegretol, talk to your doctor
Before you start to take it
Tell your doctor if you are allergic to any other medicines, foods, dyes or preservatives.
Your doctor will want to know if you are prone to allergies.
Tell your doctor if you have, or have had, any medical conditions, especially the
prostate problems or if you cannot retain your urine
liver or kidney problems
problems with your blood in the past that were caused by medicines you were taking
a mental disorder such as depression or schizophrenia
Tell your doctor if you have an intolerance to fructose. In that case, you should
not take Tegretol liquid but you can take Tegretol tablets.
Each mL of Tegretol liquid contains 175 mg of sorbitol. Sorbitol is converted by the
liver to fructose. If people with intolerance to fructose take sorbitol, it can lead
to stomach upset and diarrhoea.
Tegretol liquid contains parahydroxybenzoates which may cause allergic reactions.
Tell your doctor if you are of Asian descent, particularly if you are Chinese or Thai.
Your doctor may want to do a genetic test before you take Tegretol for the first time.
The risk of serious skin reactions in patients of Han Chinese or Thai origin associated
with carbamazepine or chemically-related compounds 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 Tegretol.
Tell your doctor if you are pregnant or intend to become pregnant.
Your doctor will discuss with you the potential risk of taking Tegretol during pregnancy
since it may cause harm or abnormalities in your baby during pregnancy and soon after
birth. But, if you have epilepsy, it is very important to control your fits while
you are pregnant. Your doctor can help you decide whether or not you should take Tegretol
in this case.
Tell your doctor if you are breast-feeding or plan to breast-feed.
Tegretol passes into breast milk but it is unlikely to affect your baby. With the
advice of your doctor, you may breast-feed provided that you watch your baby for any
signs of an unwanted side effect. If your baby develops a skin rash, becomes very
sleepy or has other unusual symptoms, do not breast-feed again until you speak to
If you have not told your doctor about any of these things, tell him/her before you
