1. What Cyprone 50 is used for
Cyprone 50 is an antiandrogenic hormone medication containing the active ingredient cyproterone acetate, which is used to 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.
Androgenic hormones are generally required for cancer of the prostate gland to grow. Cyprone 50 works in two ways. Firstly they stop the androgenic hormones (testosterone) present in your body from being able to attach to the cancer cells.
Secondly they decrease the amount of androgen hormone present in your blood stream by an effect on the hormonal mechanisms that control androgen production by the body, Cyprone 50 can be used to reduce the sex drive of men with sexual deviations.
It is also used in the treatment of women who have a problem with facial or chest hair, are balding or have severe acne.
Cyprone 50 is only available on a doctor's prescription.
There is no evidence that Cyprone 50 is addictive.
2. Before you take Cyprone 50
Cyprone 50 can rarely cause severe damage to your liver, resulting in jaundice and hepatitis.
Your doctor should perform a blood test to check your liver before starting you on Cyprone 50 and again if liver disease is suspected.
Yellowing of the skin/eyes, darkening of the urine and abdominal pain or swelling should be all reported immediately to your doctor.
As with other sex steroids, benign and malignant liver changes have been reported in isolated cases.
In very rare cases, liver tumours may lead to life-threatening bleeding into the stomach. You must inform your doctor of the occurrence of unusual upper abdominal complaints which do not disappear spontaneously within a short time.
Cyprone 50 has been observed to attach itself to the genetic material in animal and human liver cells. It would appear, however, that this does not lead to an increase in liver cancer. Female patients should be aware that the long term effects of Cyprone 50 on fertility are not known. A doctor should carry out a thorough gynaecological examination before starting treatment.
Cyprone 50 causes a decrease in sperm count. It may take between 3 to 20 months for the sperm count to return to normal once therapy has been stopped. Male patients may need to have a sperm count.
