Anastrozole pour le cancer du sein

About anastrozole

Treatment options for women with cancer du sein include surgery, radiotherapy, chemotherapy and hormone treatment. Often a combination of two or more of these treatments is used. Anastrozole is a hormone treatment.

Some breast cancers need the hormone oestrogen to grow. In women who have been through the menopause, the main source of oestrogen is through the change of sex hormones called androgens into oestrogen. An enzyme called 'aromatase' is needed for this change to occur. Anastrozole works by blocking (inhibiting) this enzyme. This reduces the amount of oestrogen in your body, which slows the growth of the cancer cells.

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 anastrozole it is important that your doctor knows:

• If you are still having menstrual periods - if you have not gone through the menopause you should not take anastrozole.

• If you have been told you have a loss of bone density (osteoporosis).

• If you have problems with the way your liver works, or problems with the way your kidneys work.

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

• If you are taking 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. It is particularly important that your doctor knows if you are taking a medicine called tamoxifen, or any oestrogen-containing medicines such as hormone replacement therapy (HRT).

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

• Take one 1 mg tablet of anastrozole each day, exactly as your doctor tells you to. Your dose will be printed on the label of the tablet pack to remind you.

• You may take anastrozole at whatever time of day you find easiest to remember, but try to take your doses at the same time each day. This will help you to avoid missing any doses.

• You can take the tablet before or after a meal.

• Si vous oubliez de prendre une dose, prenez-la dès que vous vous en souvenez. Si vous ne vous en souvenez que le lendemain, sautez la dose oubliée. Ne prenez pas deux doses ensemble pour compenser une dose oubliée.

• Try to keep your regular appointments with your doctor or clinic. This is so your doctor can check on your progress. Anastrozole lowers the levels of female hormones in your body, which can reduce the strength of your bones. You will need to have bone density tests (before and during your treatment) to check for this.

• Anastrozole is a long-term treatment so it's important to continue to take the tablets regularly unless your doctor tells you otherwise. It is likely you will need to take the tablets for five years.

• If you are having an operation or dental treatment, tell the person carrying out the treatment that you are taking anastrozole.

• Si vous achetez des médicaments, vérifiez avec un pharmacien qu'ils sont sûrs à prendre avec vos autres médicaments.

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 anastrozole. 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.

Si vous ressentez d'autres symptômes que vous pensez être dus aux comprimés, parlez-en à votre médecin ou à votre pharmacien pour obtenir des conseils supplémentaires.

• Gardez tous les médicaments hors de la portée et de la vue des enfants.

• Conserver dans un endroit frais et sec, à l'abri de la chaleur et de la lumière directes.
