What Carbamazepine Sandoz is used for
Carbamazepine Sandoz 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 depression.
Carbamazepine Sandoz 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. This medicine also regulates other nerve functions in the body.
Carbamazepine Sandoz 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 for you. Your doctor may have prescribed it for another reason.
This medicine is available only with a doctor's prescription. There is no evidence that his medicine is addictive.
Before you take Carbamazepine Sandoz
When you must not take it
Do not take this medicine if you have an allergy to:
- carbamazepine, the active ingredient, or any of the other ingredients listed at the end of this leaflet
- any other medicine containing carbamazepine
- tricyclic antidepressants, which are medicines used to treat depression.
Tell your doctor if you are allergic to oxcarbazepine 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 carbamazepine.
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 this medicine 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 this medicine if you have or have had any of the following medical conditions:
- severe liver or heart disease
- a disease of the blood
- an irregular heartbeat caused by a condition called AV block
- systemic lupus erythematosus, also called SLE
- hepatic porphyria, a disturbance in the production of porphyria, 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 this medicine 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 this medicine, talk to your doctor or pharmacist.
Before you start to take it
Tell your doctor if you are allergic to any other medicines, foods, preservatives or dyes. 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 following:
- heart problems
- prostate problems of 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 are of Asian descent, particularly if you are Chinese or Thai. Your doctor may want to do a genetic test before you take this medicine 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 Carbamazepine Sandoz.
Tell your doctor if you are pregnant or intend to become pregnant. This medicine may affect your baby during pregnancy and soon after birth. However, 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 Carbamazepine Sandoz in this case.
Tell your doctor if you are breastfeeding or plan to breastfeed. This medicine passes into breast milk but it is unlikely to affect your baby. With the advice of your doctor you may breastfeed 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 breastfeed again until you speak to your doctor.
If you have not told your doctor about any of the above, tell him/ her before you start taking Carbamazepine Sandoz.

How to take Carbamazepine Sandoz
Follow all directions given to you by your doctor or pharmacist carefully. These directions may differ from the information contained in this leaflet.
If you do not understand the instructions, ask your doctor or pharmacist for help.
How much to take
Your doctor will tell you how much Carbamazepine Sandoz you need to take each day. This may depend on your age, your medical condition and whether or not you are taking other medicines.
Your doctor will usually start your treatment with a low dose and then slowly increase it to the lowest amount needed to control your condition. Some people will need higher doses than other people will.
How to take it
Swallow the tablets with a full glass of water.
When to take it
Take your medicine during or after a meal. This helps to prevent stomach upset.
Carbamazepine Sandoz is usually taken in 2 or 3 doses during the day. But your doctor may tell you to take it more or less often, depending on your situation.
If you forget to take it
If your next dose is not due for more than 2 or 3 hours, take the missed dose as soon as you remember. Then take your next dose at the usual time and continue on with your normal schedule.
If your next dose is due within 2 or 3 hours, skip the missed dose. Take your next dose at the usual time and continue on with your normal schedule.
Do not take a double dose to make up for the dose that you missed. This may increase the chance of you getting an unwanted side effect.
If you are not sure what to do, ask your doctor or pharmacist.
If you have trouble remembering to take your medicine, ask your pharmacist for some hints.
How long to take it
Continue taking your medicine for as long as your doctor tells you. This medicine helps to control your condition, but does not cure it. It is important to keep taking your medicine even if you feel well.
Do not stop taking Carbamazepine Sandoz or lower the dose without first checking with your doctor. Do not let yourself run out of medicine over the weekend or on holidays. Stopping your medicine suddenly or lowering the dose may cause unwanted side effects or make your condition worse. If you are taking this medicine to treat epilepsy, you could develop seizures (fits). Your doctor will usually reduce the dose slowly before you can stop taking it completely.
If you take too much (overdose)
Immediately telephone your doctor or the Poisons Information Centre (telephone 13 11 26) for advice, or go to Accident and Emergency at the nearest hospital, if you think that you or anyone else may have taken too much Carbamazepine Sandoz. Do this even if there are no signs of discomfort or poisoning.
Keep the telephone numbers for these places handy.
Some of the symptoms of an overdose may include agitation, disorientation, fainting, vomiting, difficulty breathing, fast and irregular heartbeat, blurred vision, shakiness and slurred speech. If you are taking the controlled release (CR) tablets, it may take longer for you to notice these effects.
While you are taking Carbamazepine Sandoz
Things you must do
If you become pregnant while taking this medicine, tell your doctor immediately. Your doctor can discuss with you the risks of taking it while you are pregnant.
Be sure to keep all of your doctor's appointments so that your progress can be checked. To help prevent unwanted side effects from happening, your doctor may want to do some tests before you start taking Carbamazepine Sandoz and from time to time during the course of your treatment.
Contact your doctor immediately if at any time you have thoughts of harming or killing yourself. A number of people being treated with antiepileptics have had such thoughts or behaviour.
Tell your doctor if, for any reason, you have not taken your medicine exactly as prescribed. Otherwise your doctor may think that it was not effective and change your treatment unnecessarily.
Before having any surgery or emergency treatment, tell the doctor or dentist in charge that you are taking this medicine. This medicine may interfere with some of the medicines used during surgery.
If you are about to be started on any new medicine, remind your doctor and pharmacist that you are taking Carbamazepine Sandoz.
Tell any other doctors, dentists and pharmacists who treat you that you are taking this medicine.
Things you must not do
Do not stop taking your medicine or lower the dosage without checking with your doctor.
Do not use Carbamazepine Sandoz to treat any other complaints unless your doctor tells you to.
Do not give this medicine to anyone else, even if their symptoms seem similar to yours or they have the same condition as you do.
Things to be careful of
Avoid drinking grapefruit juice while you are being treated with this medicine. Grapefruit juice may interact with Carbamazepine Sandoz and affect how your body uses this medicine.
Be careful driving or operating machinery until you know how Carbamazepine Sandoz affects you. Children should be careful when riding bicycles or climbing trees. This medicine may cause dizziness, drowsiness, blurred vision, double vision or lack of muscle coordination in some people, especially when you first start to use it or when the dose is increased.
Be careful when drinking alcohol while you are taking this medicine. The combination could make you more sleepy, dizzy or light-headed than usual. Your doctor may suggest you avoid alcohol while you are being treated with Carbamazepine Sandoz.
When outdoors, wear protective clothing and use at least a 15+ sunscreen. Do not use a sunlamp or tanning bed or booth. This medicine may cause your skin to be much more sensitive to sunlight than it normally is. Exposure to sunlight may cause a skin rash, itching, redness or severe sunburn. If your skin does appear to be burning, tell your doctor.
Tell your doctor or pharmacist as soon as possible if you do not feel well while you are taking Carbamazepine Sandoz.
All medicines can have side effects. Sometimes they are serious, most of the time they are not. You may need medical attention if you get some of the side effects.
