WHAT CYPRONE 100 IS USED FOR
Cyprone 100 contains cyproterone acetate as the active ingredient.
Cyproterone acetate belongs to a group of medicines called anti-androgens. Androgens such as testosterone are natural male sex hormones. In some types of prostate cancer, androgens may help the cancer cells to grow. By blocking these hormones, 100 may slow or stop the growth of cancer.
Cyprone 100 may be used in combination with other medications 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.
Cyprone 100 is for use only in men.
This medicine is available only with a doctor’s prescription.
There is no evidence that Cyprone 100 is addictive.
Ask your doctor if you have any questions about why this medicine has been prescribed for you.
Your doctor may have prescribed it for another reason.
