1. WHAT CYPROTERONE TABLETS ARE AND WHAT THEY ARE USED FOR
The active ingredient in your tablets is cyproterone acetate, which belongs to a group of medicines called anti-androgens. These work by blocking the actions of male sex hormones (androgens) which are released naturally in your body. They also reduce 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 relieve the symptoms of a tumour of the prostate gland.
It can also be taken by males to control an over active sex drive.
