Haloperidol long-acting injection

About haloperidol long-acting injection

Schizofreni is a serious mental health condition that causes disordered ideas, beliefs and experiences. Haloperidol is used to relieve the symptoms of schizophrenia and other similar mental health problems. Such symptoms can include hearing, seeing, or sensing things that are not real, having mistaken beliefs, and feeling unusually suspicious.

Haloperidol works on the balance of chemical substances which act on the nervous system in your brain.

Long-acting, or 'depot', injections are used to maintain your recovery once your symptoms have been eased by taking tablets or capsules. The injection slowly releases haloperidol into your body and is given every four weeks. The main advantage of a depot injection is that you do not have to remember to take tablets every day.

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 having haloperidol injections it is important that your doctor or pharmacist knows:

• Om du är gravid, försöker bli gravid eller ammar.

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

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

• If you have a breathing problems.

• If you have any of the following: epilepsy, Parkinson's disease, depression, increased pressure in your eyes (glaucoma) or a condition causing muscle weakness, called myasthenia gravis.

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

• If you have a tumour on your adrenal gland (phaeochromocytoma).

• If you have been told you have low levels of salts (electrolytes) in your blood.

• If you have ever had an allergic reaction to any medicine.

• 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.

• Before you start this treatment, read the manufacturer's printed information leaflet from inside your pack. The leaflet will give you more information about haloperidol and a full list of side-effects which you may experience from having it.

• Haloperidol long-acting injection will be given to you by your doctor or nurse. It is given by injection into a muscle in your buttocks.

• If you haven't received an injection like haloperidol before, a small dose is usually given as a test before you have a normal dose. This is to see how well you tolerate the injection.

• You may be asked to continue taking your current tablets or capsules for a short while after you have had your first injection. This is because it can take a few weeks before you feel the full effect from the injection.

• If you miss an appointment for an injection, you should contact your doctor's surgery to make another appointment as soon as possible. This is because the injection should be given to you without further delay.

• Treatment with haloperidol injection may need to continue for several months or even years. Your dose will be reduced gradually to make sure your symptoms don't return.

• Your treatment will require careful monitoring to make sure that you get the best possible benefit from haloperidol. Keep your regular doctor's appointments so your progress can be checked. You will need to have some tests from time to time.

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

• If you buy or take any 'over-the-counter' medicines, check with a pharmacist that they are suitable for you to take with haloperidol.

• If you drink alcohol, ask your doctor for advice about drinking while you are on haloperidol. Alcohol may increase the chance that you experience side-effects and may not be recommended for you.

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

• Haloperidol 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 have diabetes you may need to check your blood glucose more frequently, as haloperidol may affect the levels of sugar in your blood. Your doctor will be able to advise you about this.

Förutom sina nyttiga effekter kan de flesta läkemedel orsaka oönskade biverkningar, även om inte alla upplever dem. Dessa förbättras vanligtvis när din kropp anpassar sig till det nya läkemedlet, men tala med din läkare eller apotekare om någon av följande biverkningar fortsätter eller blir besvärliga.

Viktigt: if you experience any 'flu-like' symptoms including any muscle stiffness, a very high temperature, feeling confused or sweaty, and a fast heartbeat, you must contact your doctor immediately. These may be signs of a rare but serious condition known as neuroleptic malignant syndrome.

Om du upplever några andra symtom som du tror kan bero på denna medicin, tala med din läkare eller apotekare.

• Förvara alla läkemedel utom räckhåll och synhåll för barn.

• Förvara på en sval, torr plats, borta från direkt värme och ljus.
