Procur is the brand name for tablets containing 50 mg of the antiandrogenic substance, cyproterone acetate as the active ingredient.

As well as its active ingredient, Procur contains lactose, cellulose-microcrystalline, croscarmellose sodium, povidone and magnesium stearate.

What is Procur used for and how does it work?

Procur is an antiandrogenic hormone medication which has several different uses. It is used in men 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 “hot flushes” or “sweats” and to prevent any initial worsening of the disease.

Cancer of the prostate gland generally requires androgenic hormones to grow. Procur works in two ways. Firstly it stops the androgen hormones (testosterone) present in your body from being able to attach to the cancer cells. Secondly by an effect on the hormonal mechanisms that control androgen production by the body, it decreases the amount of androgen hormone present in your blood stream.

Procur tablets are also used to reduce the male sex drive in certain cases.

It is used in the treatment of women who have a problem with facial or chest hair, are balding or have severe acne.

Procur is only available on a doctor’s prescription.

There is no evidence that Procur tablets are addictive

Before you take Procur

Procur 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 Procur and again if liver disease is suspected. Yellowing of the skin/eyes, abdominal pain or swelling and darkening of the urine 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. Tell your doctor if you have upper abdominal complaints. Procur has been observed to attach itself to the genetic material in animal and human liver cells. However an increase in liver cancers has not been seen in humans.

Female patients should be aware that the long term effects of Procur tablets on fertility are not known. A thorough gynaecological examination should be carried out by a doctor before starting treatment.

Pregnant women must not take Procr therefore pregnancy must be excluded at the time therapy is commenced in women of child-bearing age. Appropriate contraception should be commenced before starting Procur to prevent pregnancy and control the menstrual cycle. You should discuss this with your doctor before taking Procur.

Procur tablets causes a decrease in sperm count. It may take 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.
