What CYPROCUR 50 tablets are used for

CYPROCUR 50 tablets are an anti-androgenic 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.

CYPROCUR 50 tablets work 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.

CYPROCUR 50 tablets can also 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.

CYPROCUR 50 tablets are only available on a doctor's prescription.

There is no evidence that this medicine is addictive.

For males, tell your doctor if fertility after treatment is important. In this case, it is advisable to have a sperm count before taking CYPROCUR 50 to establish your fertility before commencing therapy, as this medicine can cause 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.

If you have not told your doctor about any of the above, tell them before you start taking CYPROCUR 50 tablets.

Female patients should be aware that the contraceptive action of the combined treatment of CYPROCUR 50 tablets and ethinyloestradiol may be reduced by diarrhoea or vomiting shortly after taking a tablet. In these cases, an additional form of contraception such as a diaphragm or condom should be used for the remainder of the cycle.

In wo
men taking combined CYPROCUR 50 tablets/ ethinyloestradiol treatment, if light bleeding or spotting occurs during the 3 weeks in which the tablets are being taken, do not stop taking your tablets.

However, if bleeding is heavy, consult your doctor immediately.

Side effects

Tell your doctor or pharmacist as soon as possible if you do not feel well while you are taking CYPROCUR 50. All medicines can have side effects. If they occur, most are likely to be minor and temporary. However, some may be serious and need medical attention.

Ask your doctor or pharmacist to answer any questions you may have.

The most common side effect is tiredness and loss of concentration which may affect your ability to drive or operate machinery.

CYPROCUR 50 tablets may occasionally result in gynaecomastia (swelling of the breast area which is sometimes also associated with tenderness or sensitivity of the breast area to touch), diminished libido, changes in body weight, nausea, allergy, depressive moods, headache, shortness of breath and blood clotting (which may lead to a clot on the lungs, stroke or heart attack) and increase in blood pressure in women.

In males, if you were fertile before treatment, CYPROCUR 50 may also result in your inability to produce sperm (infertility). Fertility is usually regained within a few months of discontinuing therapy. This medicine may also result in the inability to get or maintain an erection (impotence). This ability is usually also regained within a few months of discontinuing therapy.

Yellowing of the skin/eyes, darkening of the urine and abdominal pain or swelling should be all reported immediately to your doctor.

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.
