Drug Information
13 reviews for Clozapine (Clozaril)
Clozaril contains Clozapine.
Clozapine is an antipsychotic used for schizophrenia when at least two other medicines have not worked. It is often very effective where others fail.
Because it can rarely cause a serious drop in white blood cells, everyone taking clozapine must have regular blood tests.
What is it used for?
- Treatment-resistant schizophrenia
- Reducing suicidal behaviour in schizophrenia
- Psychosis in Parkinson's disease
How does it work?
Clozapine acts on many chemical messengers in the brain, including dopamine and serotonin. This helps reduce hallucinations, delusions and disordered thinking.
This information is written in simple words to help you understand this product. It does not replace advice from your doctor or pharmacist.
Read these points before you start. If any of them apply to you, talk to your doctor or pharmacist first.
- Older people with dementia who take antipsychotic medicines have a higher risk of stroke and death. It is not approved for behaviour problems caused by dementia.
- It can make you sleepy or dizzy. Do not drive or use machines until you know how it affects you. Avoid alcohol.
- It can raise blood sugar, cholesterol and weight. Your doctor will check your weight, blood sugar and blood fats regularly.
- Tell your doctor if you have heart problems, epilepsy, diabetes, Parkinson's disease, glaucoma, trouble passing urine, or a history of blood clots.
- Avoid getting too hot or dehydrated, as your body may not cool down as well.
- Do not stop taking it suddenly. Your doctor will lower the dose slowly.
- Tell your doctor if you are pregnant, planning a pregnancy or breastfeeding.
- You must have regular blood tests: weekly at first, then less often. Do not take it if you miss your blood tests.
- It can cause severe constipation, which can be dangerous. Tell your doctor if you have not opened your bowels for 2 days.
- Smoking lowers clozapine levels. Tell your doctor if you start or stop smoking, as your dose may need changing.
- Tell your doctor or pharmacist about every other medicine, vitamin or herbal product you use.
- Keep this product out of the reach and sight of children.
Like all medicines, Clozaril can cause side effects, but not everybody gets them.
Common side effects
- Feeling very sleepy
- Drooling, especially at night
- Constipation
- Weight gain
- Fast heartbeat
- Dizziness
These are usually mild and often get better as your body gets used to it. Tell your doctor if they bother you or do not go away.
Stop using it and get medical help straight away if you notice:
- High fever, stiff muscles, sweating, confusion and a fast heartbeat (a rare, serious reaction called neuroleptic malignant syndrome)
- Uncontrollable movements of the face, tongue or body
- A fast, pounding or uneven heartbeat, or fainting
- Signs of high blood sugar: very thirsty, passing lots of urine, feeling very tired
- Pain, swelling or redness in one leg, or sudden chest pain and breathlessness (possible blood clot)
- Sore throat, fever, mouth ulcers or flu-like symptoms (possible low white blood cells)
- Chest pain, breathlessness or fast heartbeat, especially in the first 2 months (possible heart inflammation)
- Severe constipation, stomach pain or swollen belly
- A fit (seizure)
This is not a complete list. If you notice anything unusual, ask your doctor or pharmacist.
- Take it once or twice a day, as your doctor tells you, with or without food.
- It is started at a very low dose (12.5 mg) and raised slowly over a few weeks, usually to 200 mg to 450 mg a day.
- Go to all your blood tests. Your pharmacy may only give you clozapine if your blood results are OK.
- If you miss more than 2 days, do not restart at your usual dose. Contact your doctor.
If you miss a dose: Take it as soon as you remember, unless it is nearly time for your next dose. Never take two doses at once.
If you use too much: Contact your doctor, a poison control centre or your local emergency number straight away, even if you feel fine. Take the pack with you.
How to store it: Keep it in its original pack at room temperature (below 25°C / 77°F), away from heat, damp and direct sunlight. Do not use it after the expiry date.
