Chlorpromazine belongs to a group of medicines called 'phenothiazines'. It is prescribed for a variety of conditions, many of which are unrelated.

It is prescribed for:

  • The symptoms of schizophrenia and other similar mental health problems which affect thoughts, feelings and behaviours. These problems are called psychoses.

  • The short-term treatment of severe anxiety, agitation, or sudden dangerous behaviour.

  • Children with autism.

  • Sickness (nausea) associated with advanced or terminal illnesses.

  • Hicka which cannot be otherwise stopped.

Before taking chlorpromazine

Some medicines are not suitable for people with certain conditions, and sometimes a medicine may only be used if extra care is taken. For these reasons, before you start taking chlorpromazine it is important that your doctor knows:

  • Om du är gravid eller ammar.

  • If you have a heart condition or blood vessel disease.

  • If you have liver, kidney, thyroid, or prostate problems.

  • If you have breathing problems.

  • If you have any of the following: epilepsy, diabetes, depression, Parkinson's disease, raised pressure in your eye (glaucoma), or myasthenia gravis, a condition which causes muscle weakness.

  • If you have ever had yellowing of your skin or the whites of your eyes (jaundice) or a blood disorder.

  • If you have a tumour on your adrenal gland, a condition called phaeochromocytoma.

  • Om du någonsin har haft en allergisk reaktion mot en medicin.

  • Om du tar eller använder några andra läkemedel. Detta inkluderar alla läkemedel du tar som finns att köpa utan recept, samt växtbaserade och komplementära läkemedel.

How to take chlorpromazine

  • Before you start the treatment, read the manufacturer's printed information leaflet from inside your pack. It will give you more information about chlorpromazine, and will also provide a full list of the side-effects which you may experience from taking it.

  • Your dose will depend upon the reason you have been prescribed it, so take chlorpromazine exactly as your doctor tells you to. As a guide, it is often prescribed to be taken three or four times daily. Try to get into the habit of taking your doses at the same times each day, as this will help you to avoid missing any. You can take chlorpromazine before or after meals.

  • Swallow the tablets whole with a drink of water - do not break or crush the tablets. If you have any difficulties swallowing the tablets, let your doctor know so that you can be prescribed liquid medicine instead.

  • If you forget to take a dose, take it as soon as you remember unless it is nearly time for your next dose, in which case leave out the missed dose. Do not take two doses together to make up for a missed dose.

Få ut det mesta av din behandling

  • Keep your regular doctor's appointments so your progress can be checked. If you are taking chlorpromazine long-term, you may need to have some tests from time to time.

  • If you drink alcohol, ask your doctor for advice about drinking while you are on chlorpromazine. Alcohol will increase the chance that you experience side-effects and is unlikely to be recommended for you.

  • Chlorpromazine may cause your skin to become more sensitive to sunlight than normal. Use a sunscreen that protects against UVA light and has a sun protection factor (SPF) of at least 15, especially in strong sunlight or until you know how your skin reacts. Do not use sunbeds.

  • If you are having an operation, tell the person carrying out the treatment which medicines you are taking. This is important because chlorpromazine may interfere with the anaesthetic you receive.

  • If you buy or take any 'over-the-counter' medicines, check with a pharmacist that they are suitable to take with chlorpromazine. Antacid remedies should not be taken at the same time, as they reduce the amount of chlorpromazine absorbed by your body.

  • If you have diabetes check your blood glucose levels regularly, as chlorpromazine can affect the levels of sugar in your blood.

  • Smoking may affect the amount of chlorpromazine in your body. Let your doctor know if you start or stop smoking while you are taking chlorpromazine.

  • When chlorpromazine has been taken for a while, stopping treatment suddenly can cause problems. If you have been taking it regularly your doctor will probably want you to reduce your dose gradually if this becomes necessary.

Vanliga frågor

What is the primary class of medication chlorpromazine belongs to?

Chlorpromazine is classified as a phenothiazine antipsychotic medicine.

Are there any specific medical conditions that would make chlorpromazine unsuitable for me?

Yes, some conditions require extra care or may mean the medicine is unsuitable. Your doctor needs to know if you have a heart condition, blood vessel disease, liver, kidney, thyroid, or prostate problems, breathing difficulties, epilepsy, diabetes, depression, Parkinson's disease, glaucoma, myasthenia gravis, a history of jaundice or a blood disorder, or a tumour on your adrenal gland (phaeochromocytoma).

Can I take chlorpromazine with other medications, even those I buy without a prescription?

You should inform your doctor about all medicines you are taking, including those available without a prescription, as well as herbal and complementary medicines. It's especially important to check with a pharmacist about 'over-the-counter' medicines, as some may not be suitable to take with chlorpromazine. For example, antacid remedies should not be taken at the same time as they can reduce how much chlorpromazine your body absorbs.

If I need to stop taking chlorpromazine, can I do so immediately?

If you have been taking chlorpromazine regularly for a while, stopping treatment suddenly can cause problems. Your doctor will likely recommend reducing your dose gradually if it becomes necessary to stop taking the medication.

What should I do if I experience muscle stiffness or a high temperature while taking chlorpromazine?

If you experience symptoms such as muscle stiffness, a very high temperature, feeling confused, a fast heartbeat, and sweating, you should contact your doctor immediately. These could be signs of a rare but serious condition called neuroleptic malignant syndrome.
