Gel d'isotrétinoïne pour l'acné

About isotretinoin gel

Acne is the common cause of spots. Most people with acne are aged between 12 and 25, but some older and younger people are affected too. Small sebaceous glands lie just under your skin surface and make an oil (sebum) that keeps your skin supple and smooth. Tiny pores on your skin allow the sebum to come on to the surface of your skin. In acne, some of these pores become blocked, causing small pimples, blackheads and whiteheads (comedones).

Applying isotretinoin to the areas of your skin with acne will help to unblock pores and treat blackheads or whiteheads. It also has some effect on reducing inflammation. If your spots are inflamed, you may be prescribed a brand called Isotrexin® as this gel also contains an antibacterial agent called erythromycin.

Isotretinoin is also available as capsules for more severe forms of acne which have not got better by using rub-on skin treatments. There is a separate medicine leaflet which contains more information about this, called Isotretinoin capsules for acne.

Before using isotretinoin gel

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 using isotretinoin gel it is important that your doctor knows:

• If you are pregnant, trying for a baby or breastfeeding. You must not use isotretinoin gel if you could be pregnant.

• Si vous avez un problème de peau autre que l'acné, par exemple si vous souffrez d'eczéma ou de rosacée.

• Si vous ou un membre de votre famille proche avez déjà eu un cancer de la peau.

• Si vous prenez ou utilisez d'autres médicaments. Cela inclut les crèmes que vous utilisez et qui sont disponibles sans ordonnance.

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

How to use isotretinoin gel

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

• Apply isotretinoin gel exactly as your doctor tells you to. It is best if you wash and gently dry the affected areas of your skin before you apply isotretinoin. A general point is that you should apply it to all of the area where your spots occur and not just to each spot. It is usual to apply it once or twice a day at first, although your doctor may suggest you use it less than this once your skin has improved. You only need to apply a thin layer of gel. Remember to wash your hands after you have finished applying the gel.

• If you have recently been using a preparation for your acne that causes your skin to peel, allow your skin to recover for a few days before you start using isotretinoin gel.

• Do not use the gel on any areas of your skin which are sunburnt or sore. Also, try to avoid getting it on the sensitive areas of your skin in or around your nostrils, your eyes and your mouth. Try not to let it build up in the folds or creases of your skin.

Tirer le meilleur parti de votre traitement

• Il est recommandé d'utiliser un savon doux et de l'eau tiède pour se laver, car l'eau très chaude ou très froide peut aggraver l'acné. Vous ne pouvez pas nettoyer les points noirs. La pointe noire d'un point noir est en fait un pigment de la peau et ne peut pas être enlevée en nettoyant ou en frottant.

• Si votre peau devient très sèche, il peut être utile d'utiliser une crème hydratante (de préférence sans parfum et à base d'eau). N'utilisez pas de pommades ou de crèmes riches en huile, car elles pourraient à nouveau obstruer vos pores.

• You can use make-up and moisturisers, but do not apply them at the same time as you use isotretinoin gel. Try to avoid any skin products which exfoliate or dry your skin.

• Isotretinoin gel can make your skin more sensitive to sunlight than usual. A sun protection cream can help if you are out in the sun on bright days, even if it is cloudy. Do not use sunbeds.

• It is normal for isotretinoin treatment to take several weeks before there is a noticeable improvement in your skin. The most common reason for treatment failure is stopping treatment too soon thinking it is not working. If there is no improvement despite having used the gel for eight weeks, speak with your doctor again as there are other treatments which could be more suited to your condition.

• You should avoid getting pregnant while you are using isotretinoin as there is a slight risk of harm to unborn babies. If necessary, discuss with your doctor which types of contraception are suitable for you and your partner.

• Once your spots have cleared, acne commonly flares up again if you stop treatment. To prevent this, it is usual to carry on with a maintenance treatment after your spots have gone. The dose used to prevent spots from returning is often lower than that used to treat acne. It is common to need maintenance treatment for a number of years to keep acne away.

Can isotretinoin gel cause problems?

Along with their useful effects, most medicines can cause unwanted side-effects although not everyone experiences them. The table below contains some of the most common ones associated with isotretinoin gel. You will find a full list in the manufacturer's information leaflet supplied with your medicine. The unwanted effects often improve as your body adjusts to the new medicine, but speak with your doctor or pharmacist if any of the following continue or become troublesome.

If you experience any other symptoms which you think may be due to isotretinoin, speak with your doctor or pharmacist for further advice.
