Capsules d'acitrétine pour le psoriasis

About acitretin

Acitretin is used to treat severe skin conditions where the surface of the skin has become thick and scaly. Normally, as new skin cells are produced, older ones are lost. If the skin cells in the outer layer of your skin multiply faster than normal, the old skin cells can build up on the surface of your skin, causing thick or scaly patches.

Acitretin is a retinoid medicine, which means simply that it is related to vitamin A. Our bodies use vitamin A to maintain a healthy skin. Acitretin helps to control conditions like psoriasis by making your skin grow more normally.

Acitretin is sometimes used as a treatment on its own but, more often, it is used alongside other preparations to help the skin's condition.

Before taking acitretin

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 acitretin it is important that your doctor knows:

• If you are pregnant, trying for a baby or breastfeeding. This is because you must pas take acitretin if you think you are (or think you may be) pregnant.

• Si vous avez des problèmes avec le fonctionnement de votre foie, ou des problèmes avec le fonctionnement de vos reins.

• If you have high levels of fats (lipids) such as cholesterol in your blood.

• Si vous avez le diabète (diabète sucré).

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

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

How to take acitretin

• Before you start the treatment, read the manufacturer's printed information leaflet from inside your pack and any other information that you are given by your doctor. The leaflets will give you more information about acitretin and will provide you with a full list of the side-effects which you could experience from taking it.

• Take the capsules exactly as your doctor tells you to. Acitretin is taken once daily. Your doctor will tell you how many capsules to take and this will also be printed on the label of the pack to remind you about what the doctor said to you. Take each of your doses with a snack, or just after eating a meal. It is a good idea to swallow the capsules with a drink of water or milk.

• Try to take your doses of acitretin at the same time of day each day, as this will help you to remember to take them regularly. If you forget to take a dose at the usual time, take it when you remember. If you do not remember until the following day, then miss out the forgotten dose. Do not take two doses together to make up for a missed dose.

Tirer le meilleur parti de votre traitement

• It is important for you to keep your regular appointments with your doctor. This is so your doctor can check on your progress. You will need to have regular blood tests during the treatment. The tests will check that your lipid levels are normal and that your liver remains healthy. If you are a woman, you may also need to have regular tests to confirm that you are not pregnant.

• It can take 2-4 weeks before you start to feel the benefit from the capsules and it may take up to four months before you feel the maximum benefit. A course of treatment is likely to last for up to six months but occasionally it can be for longer than this.

• Acitretin is harmful to unborn babies, so it is very important that you do not become pregnant while you are taking it. Your doctor will advise you about suitable contraception and this may include using more than one method. You should continue to use suitable contraception for at least three years after you finish your course of treatment. If at any time during your treatment or the three years afterwards, you think you may be pregnant, contact your doctor for advice straightaway.

• If you buy any medicines, vitamins, or herbal preparations, please check with your doctor or a pharmacist that they are suitable for you to take with acitretin. This is because you must not take any other preparation which contains vitamin A.

• Acitretin can cause your skin to become more sensitive to sunlight than normal. Protect your skin from sunlight even on bright but cloudy days and do not use sunbeds.

• If you normally drink alcohol, please ask your doctor for advice. Your doctor may recommend that you do not drink alcohol while you are on this medicine.

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

• You must not give blood while you are on acitretin and for at least three years after you finish taking it. This is because it could cause harm to other people.
