Cyproterone - an anti-androgen for men

About cyproterone

Cyproterone belongs to a group of medicines known as anti-androgens. This means that it blocks the actions of male sex hormones called androgens, and it also reduces the amount of male hormones your body produces. This anti-androgen action can be helpful in the treatment of two different conditions - in the treatment of prostate cancer, and to control the sex drive in men with hypersexuality.

In prostate cancer, the cancer cells need the male hormone testosterone to grow and multiply well. Hormone treatments like cyproterone block the effect of testosterone on prostate cancer cells. This slows down the growth of the cancer. Cyproterone also helps to reduce symptom 'flares' and side-effects from other treatments which may be used for the cancer, or following surgery.

In men who have hypersexuality, cyproterone is used to control sexual desire or deviation. If you are prescribed cyproterone for this reason, your doctor will ask you to sign an agreement before you start the treatment.

Cyproterone is also found in very low doses in a contraceptive tablet called co-cyprindiol. It is useful for managing acne or excess hair growth (hirsutism) whilst also providing contraception.

Before taking cyproterone

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 cyproterone it is important that your doctor knows:

• If you are under 18 years old. Cyproterone is not recommended for this age group.

• If you are depressed.

• If you have any problems with the way your liver works, or if you drink a lot of alcohol.

• Wenn Sie Diabetes haben.

• If you have blood vessel problems, such as if you have ever had a blood clot in a leg or lung.

• If you have a type of anaemia known as sickle cell anaemia.

• If you have ever had a type of brain tumour called meningioma, or if you have been diagnosed with another type of cancer (other than prostate cancer if that is what you are being treated for).

• Wenn Sie andere Arzneimittel einnehmen oder verwenden. Dazu gehören alle Arzneimittel, die Sie einnehmen und die rezeptfrei erhältlich sind, sowie pflanzliche und ergänzende Arzneimittel.

• Wenn Sie schon einmal eine allergische Reaktion auf ein Arzneimittel hatten.

How to take cyproterone

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

• Take cyproterone exactly as your doctor tells you to. How you should take the tablets will depend on what condition you are being treated for, so your doctor will give you full directions. Your dose will also be printed on the label of the pack to remind you about what the doctor said to you.

• Take your doses with a snack, or just after eating a meal. Swallow the tablets with a drink of water.

• Try to take cyproterone at the same times of day each day. This will help you to remember to take your doses regularly.

• Wenn Sie die Einnahme einer Dosis vergessen haben, nehmen Sie sie ein, sobald Sie sich daran erinnern, es sei denn, Ihre nächste Dosis ist fällig. Wenn die nächste Dosis bald fällig ist, nehmen Sie die nächste Dosis, wenn sie fällig ist, aber lassen Sie die vergessene Dosis aus. Nehmen Sie nicht zwei Dosen zusammen ein, um eine vergessene Dosis auszugleichen.

Das Beste aus Ihrer Behandlung herausholen

• Please keep your regular appointments with your doctor. Your doctor will want you to have some blood tests both before and during your treatment. The tests will check the levels of your blood cells, and that your liver stays healthy. Your doctor will also want to check that your adrenal glands are not being affected by the treatment.

• Cyproterone can make you feel tired or weak. If this happens to you, do not drive and do not use tools or machines, as these symptoms may put others as well as yourself at risk.

• Your doctor may recommend you do not drink alcohol while you are on cyproterone. This is because regularly drinking alcohol can stop cyproterone from working as well as it should.

• When you have been taking cyproterone for some weeks, your sperm count will reduce and you are likely to become unable to father a child. You must not, however, rely on cyproterone as a contraceptive. Although this infertility is likely to reverse when you stop taking cyproterone, you should speak with your doctor if you are thinking of having children in the future.

Can cyproterone 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 cyproterone. 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.

Wenn Sie andere Symptome haben, von denen Sie glauben, dass sie auf die Tabletten zurückzuführen sind, sprechen Sie bitte mit Ihrem Arzt oder Apotheker, um weiteren Rat einzuholen.
