1. What Tegretol Liquid is and what it’s used for

Tegretol Liquid is a white suspension tasting of caramel. Carbamazepine, the active ingredient in Tegretol Liquid, 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 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. Things to consider before you start to take Tegretol Liquid

Some people MUST NOT take Tegretol Liquid. 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 Liquid (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 Liquid. If the answer to any of these questions is YES, discuss your treatment with your doctor or pharmacist because Tegretol Liquid might not be the right medicine for you.

•    Are you pregnant or planning to become pregnant?

•    Are you breastfeeding?

•    Do you suffer from the sort of epilepsy where you get mixed seizures which include absences?

•    Do you have any mental illness?

•    Are you allergic to an epilepsy medicine called phenytoin?

•    Do you have liver problems?

•    Do you have kidney problems associated with low sodium blood level or do you have kidney problems and you are taking certain medicines that lower sodium blood levels (diuretics such as hydrochlorothiazide, furosemide)?

•    Are you elderly?

•    Do you have any eye problems such as glaucoma (increased pressure in the eye) or do you have difficulty retaining your urine?

•    Do you have an intolerance to some sugars? (Tegretol Liquid contains sorbitol).

Are you taking other medicines?

Because of the way that Tegretol Liquid works, it can affect, and be affected by, lots of other things that you might be eating or medicines that you are taking. It is very important to make sure that your doctor knows all about what else you are taking, including anything that you have bought from a chemist or health food shop. It may be necessary to change the dose of some medicines, or stop taking something altogether.

Tell the doctor if you are taking:

•    Hormone contraceptives, e.g. pills, patches, injections or implants. Tegretol Liquid affects the way the contraceptive works in your body, and you may get breakthrough bleeding or spotting. It may also make the contraceptive less effective and there will be a risk of getting pregnant. Your doctor will be able to advise you about this, and you should think about using other contraceptives.

•    Hormone Replacement Therapy (HRT). Tegretol Liquid can make HRT less effective.

•    Any medicines for depression or anxiety.

•    Corticosteroids (‘steroids'). You might be taking these for inflammatory conditions such as asthma, inflammatory bowel disease, muscle and joint pains.

•    Anticoagulants to stop your blood clotting.

•    Antibiotics to treat infections including skin infections and TB (e.g. ciprofloxacillin).

•    Antifungals to treat fungal infections.

•    Painkillers containing paracetamol, dextropropoxyphene, tramadol, methadone or buprenorphine.

•    Other medicines to treat epilepsy.

•    Medicines for high blood pressure or heart problems.

•    Antihistamines (medicines to treat allergy such as hayfever, itch, etc).

•    Diuretics (water tablets).

•    Cimetidine or omeprazole (medicines to treat gastric ulcers).

•    Isotretinoin (a medicine for the treatment of acne).

•    Metoclopramide or aprepitant (anti-sickness medications).

•    Acetazolamide (a medicine to treat glaucoma - increased pressure in the eye).

•    Danazol or gestrinone (treatments for endometriosis).

•    Theophylline or aminophylline (used in the treatment of asthma).

•    Ciclosporin, tacrolimus or sirolimus (immunosuppressants, used after transplant operations, but also sometimes in the treatment of arthritis or psoriasis).

•    Drugs to treat schizophrenia (e.g. paliperidone, aripiprazole).

•    Cancer drugs (e.g. temsirolimus, cyclophasphamide, lapatinib).

•    The anti-malarial drug,    mefloquine.

•    Drugs to treat HIV.

•    Levothyroxine (used to    treat hypothyroidism).

•    Tadalafil (used to treat    impotence).

•    Albendazole (used to treat worms).

•    Bupropion (used to help stop smoking).

•    A herbal remedy called St John's Wort or Hypericum.

•    Drugs or supplements containing Vitamin B (nicotinamide).

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 Liquid 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 Liquid.

Mothers taking Tegretol Liquid 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.

Will there be any problems with driving or using machinery?

Tegretol Liquid 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

•    Tegretol Liquid contains parahydroxybenzoates as preservative. These may cause allergic reactions, which may not appear immediately.

•    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 Liquid and from time to time during your treatment. This is quite usual and nothing to worry about.

3. How to take Tegretol Liquid

The doctor will tell you how much Tegretol Liquid to take and when to take it. Always follow his/her instructions carefully. The dose will be on the pharmacist's label. Check the label carefully. It is important to take the liquid at the right times. If you are not sure, ask your doctor or pharmacist.

Keep taking your medicine for as long as you have been told, unless you have any problems. In that case, check with your doctor.

Your doctor will usually start Tegretol Liquid at a fairly low dose which can then be increased to suit you individually. The dose needed varies between patients. You can take Tegretol Liquid during, after or between meals. Shake the bottle before you measure out your dose. You are usually told to take a dose two or three times a day.

To treat epilepsy the usual doses are:

Adults: 800-1,200 mg a day, although higher doses may be necessary. If you are elderly you might require a lower dose.

Children aged up to and over 1 year: Usually 10-20 mg/kg body weight daily in several divided doses. Your doctor will tell you how much liquid the child should take.

To treat trigeminal neuralgia the usual dose is: 600-800 mg a day. The maximum dose is 1200mg a day. If you are elderly you might require a lower dose. Once the pain is controlled your doctor will probably reduce the dose.

Pg 3 ^

To treat mood swings the usual dose is: 400-600 mg a day What if you forget to take a dose?

If you forget to take a dose, take one as soon as you remember. If it is nearly time for your next dose, though, just take the next dose and forget about the one you missed.

What if you take too much liquid?

If you accidentally take too much Tegretol Liquid, tell your doctor or your nearest hospital casualty department. Take your medicine pack with you so that people can see what you have taken.

4. Possible side effects
