About aripiprazole long-acting injection

Type of medicine

An antipsychotic medicine

Used for

Schizophrenia in adults

Also called

Abilify Maintena®

Available as

Long-acting intramuscular depot injection

Schizophrenia is a mental health condition that causes disordered ideas, beliefs and experiences. You will have been prescribed aripiprazole to relieve the symptoms of schizophrenia. Such symptoms include hearing, seeing, or sensing things that are not real, having mistaken beliefs, and feeling unusually suspicious. Aripiprazole works on the balance of chemical substances in your brain to help control these types of symptoms.

Long-acting, or 'depot', injections are used for maintenance once your symptoms have been eased by taking tablets. The injection slowly releases aripiprazole into your body. You will need to receive the injection regularly, once every month. The main advantage of a depot injection is that you do not have to remember to take tablets every day.

For information about taking aripiprazole tablets every day see our medicine leaflet called Aripiprazole (Abilify).

Before having aripiprazole long-acting injection

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 aripiprazole it is important that your doctor knows:

  • If you are pregnant or breastfeeding.

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

  • If you have had a stroke, or if you have been told you have 'thickening' of the blood vessels to your brain.

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

  • If you have any problems with your breathing.

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

  • 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).

  • If you have had an allergic reaction to a medicine.

  • If you are taking or using any other medicines. This includes any medicines you are taking which are available to buy without a prescription, as well as herbal and complementary medicines.

How aripiprazole long-acting injection is given

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

  • Aripiprazole injection will be given to you by a doctor or nurse. The injection is given into a muscle of your bottom (buttock) or your upper arm. You will be given an injection once every month - it is important that there is an interval of at least 26 days between each injection.

  • You may be asked to continue taking your tablets for 14 days 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.

Getting the most from your treatment

  • Your treatment will require careful monitoring to make sure that you get the best possible benefit from aripiprazole. Keep your regular doctor's appointments so that you get your injections on time, and your progress can be checked. If you miss an appointment for an injection, contact your doctor to arrange for another appointment as soon as possible.

  • If you are due to have any dental treatment or an operation, please tell the person carrying out the treatment that you have had an aripiprazole injection. This is important because it 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 aripiprazole.

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

  • If you drink alcohol, please ask your doctor for advice. Alcohol increases the risk of side-effects from aripiprazole so it is best avoided.

  • Treatment with medicines like aripiprazole can sometimes cause problems with impulsive types of behaviour. If you notice any changes in your behaviour, such as an increased desire to gamble, you must let your doctor know as soon as possible.

  • A small number of people taking medicines like aripiprazole can have thoughts about harming themselves or ending their lives. It is very important that you tell your doctor about this if it happens to you.
