Olanzapine en injection à action prolongée

About olanzapine long-acting injection

Olanzapine belongs to a group of medicines called antipsychotics. You will have been prescribed it to maintain symptom control of schizophrenia.

Schizophrenia is a mental health condition that causes disordered ideas, beliefs and experiences. Symptoms of schizophrenia include hearing, seeing, or sensing things that are not real, having mistaken beliefs, feeling unusually suspicious, and becoming withdrawn. Olanzapine is used to relieve the symptoms of schizophrenia and other similar mental health problems. It works on the balance of chemical substances in your brain.

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

Before having olanzapine long-acting injection

Some medicines are not suitable for people with certain conditions, and sometimes a medicine can only be used if extra care is taken. For these reasons, before you start having olanzapine long-acting injections, it is important that your doctor knows:

• Si vous êtes enceinte ou si vous allaitez.

• Si vous souffrez d'une maladie cardiaque ou d'une maladie des vaisseaux sanguins.

• Si vous avez des problèmes de fonctionnement du foie ou des reins.

• Si vous avez des problèmes de prostate.

• Si vous avez des problèmes respiratoires.

• If you have any of the following: epilepsy, diabetes (diabetes mellitus), 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).

• If you have a blood or bone marrow disorder.

• If you are very constipated or think you may have a blockage in your bowel.

• Si vous avez eu une réaction allergique à un médicament.

• Si vous prenez ou utilisez d'autres médicaments. Cela comprend tous les médicaments que vous prenez et qui sont disponibles sans ordonnance, ainsi que les médicaments à base de plantes et les médicaments complémentaires.

How olanzapine long-acting injection is given

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

• Olanzapine long-acting injection will be given to you in an outpatient clinic by a doctor or nurse. The injection is given into a muscle in your bottom (buttocks). As a routine, you will be asked to stay in the clinic where you can be observed for at least three hours after each injection. This is because it can make you feel tired or dizzy after it is given. You will be advised not to drive and not to use tools or machines for the remainder of the day.

• You may be asked to continue taking your current 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.

• Treatment with olanzapine is usually long-term so that your symptoms don't return.

Tirer le meilleur parti de votre traitement

• Your treatment will require careful monitoring to make sure that you get the best possible benefit from olanzapine. 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 the hospital to arrange for another appointment as soon as possible.

• Olanzapine could cause your skin to become more sensitive to sunlight than normal. Avoid strong sunlight and sunbeds, and use a sun cream with a high sun protection factor even on bright but cloudy days.

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

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

• If you are having any dental treatment or an operation, tell the person carrying out the treatment that you have had an olanzapine injection. This is important because it 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 for you to take with olanzapine.
