What is in this leaflet

This leaflet answers some common questions about Cyprocur 100.

It does not contain all of the available information. It does not take the place of talking to your doctor or pharmacist.

All medicines have benefits and risks. Your doctor has weighed the risks of you taking Cyprocur 100 against the benefits they expect it will have for you.

If you have any concerns about taking this medicine, talk to your doctor or pharmacist.

What CYPROCUR 100 is used for

Cyprocur 100 tablets contain cyproterone acetate as the active ingredient. Cyproterone acetate belongs to a group of medicines called anti-androgens. It blocks the actions of male sex hormones (androgens) which are released naturally in the body. It also reduces the production of androgens.

It has been shown that the growth of tumours of the prostate gland may be dependent on male hormones. Since cyproterone acetate blocks the action of androgens and reduces the amount of androgens produced by the body, it can be used to help treat cancer of the prostate gland.

It can also be used in conjunction with other medications or following surgical removal of the testes to treat side effects such as “sweats” or “hot flushes” and to prevent any initial worsening of the disease.

Cyprocur 100 is for use only in men.

This medicine is available only with a doctor's prescription.

There is no evidence that Cyprocur 100 tablets are addictive.
