About flupentixol long-acting injection

Type of medicine A thioxanthene antipsychotic
Used for Easing the symptoms of schizophrenia and other similar mental health problems in adults
Also called Depixol®
Available as Long-acting 'depot' injection

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

Flupentixol works by correcting the imbalance of chemical substances which act on the nervous system in your brain.

Long-acting or 'depot' injections are used once your symptoms have been eased by taking tablets. The injection slowly releases flupentixol into your body and is given every 2-4 weeks. The main advantage of a depot injection is that you do not have to remember to take tablets every day.

Before having flupentixol 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 flupentixol injections, it is important that your doctor knows:

  • If you are pregnant, trying for a baby or breast-feeding.
  • If you have a heart condition, or blood vessel disease.
  • If you have any problems with your liver, kidneys, or prostate.
  • If you have breathing difficulties.
  • If you have any of the following: diabetes, epilepsy, Parkinson's disease, depression, glaucoma (raised pressure within your eye), or myasthenia gravis (this is a condition causing muscle weakness).
  • If you have an overactive or underactive thyroid.
  • If you have porphyria (a rare inherited blood disorder), or any other problems with your blood.
  • If you have ever had jaundice (yellowing of your skin and the whites of your eyes).
  • If you have a condition called phaeochromocytoma (a tumour on your adrenal gland).
  • If you have ever had an allergic reaction to a medicine.
  • If you are taking any other medicines. This includes any medicines you are taking which are available to buy without a prescription, such as herbal and complementary medicines.

How flupentixol long-acting injection is given

  • Before you start this treatment, ask to read the manufacturer's printed information leaflet from inside the pack. The leaflet will give you more information about flupentixol and a full list of side-effects which you may experience from having it.
  • Flupentixol injection will be given to you by a doctor or nurse. If you haven't received an injection like flupentixol before, a small dose is usually given as a test one week before you have a full dose. This is to see how well you tolerate the injection. The injection is given into a muscle of your buttock (bottom) or thigh.
  • You may be asked to continue taking your tablets 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.

Getting the most from your treatment

  • Your treatment will require careful monitoring to make sure that you get the best possible benefit from flupentixol. 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.
  • Flupentixol 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 any dental treatment or an operation, tell the person carrying out the treatment that you have had a flupentixol 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 safe to take with flupentixol.
  • If you drink alcohol, ask your doctor for advice about drinking while you are on flupentixol. Alcohol can increase the chance that you experience side-effects and may not be recommended for you.
  • If you have diabetes you may need to check your blood glucose more frequently, as flupentixol may affect the levels of sugar in your blood. Your doctor will advise you about this.

Can flupentixol long-acting injection cause problems?

Along with their useful effects, most medicines can cause unwanted side-effects although not everyone experiences them. These usually improve as your body adjusts to the new medicine, but speak with your doctor or pharmacist if any of the following side-effects continue or become troublesome.

Common flupentixol side-effects What can I do if I experience this?
Pain at the site of the injection This should not last long. If the area becomes red, swollen or 'lumpy', let your doctor know
Feeling sleepy or dizzy, blurred vision If this happens, do not drive or use tools or machines
Headache Ask your pharmacist to recommend a suitable painkiller
Dry mouth Try chewing sugar-free gum or sucking sugar-free sweets
Changes in weight, difficulty sleeping, feeling agitated or confused, changes in sexual ability, breast changes, menstrual problems, producing more saliva than usual, fast heartbeats, stomach upset, feeling shaky, and difficulty passing urine Discuss these with your doctor if any become troublesome

Important: your doctor will discuss with you the possibility of unwanted side-effects that you must let your doctor know about without delay. Contact your doctor straightaway if you experience any of the following:

  • 'Flu-like' symptoms including muscle stiffness, a high temperature, confusion, a fast heartbeat and sweating. These may be signs of a rare but serious condition known as neuroleptic malignant syndrome.
  • Any abnormal face or body movements, or any involuntary muscle movements. These are called extrapyramidal symptoms.
  • A feeling of restlessness (such as not being able to sit or stand still). This is called akathisia.

If you experience any other symptoms which you think may be due to this medicine, speak with your doctor or pharmacist.
