What PROCUR tablets are used for

PROCUR tablets contain the active ingredient cyproterone acetate

Cyproterone acetate is an antiandrogen. It works by blocking the actions of male sex hormones (androgens). It also reduces the production of male hormones in the testes and inhibits ovarian function in female.

PROCUR is normally used to reduce increased sex drive (hypersexuality) in adult males or to treat inoperable prostate cancer in males or severe signs of androgenization such as excessive hairiness in women.

Your doctor may have prescribed PROCUR tablets for another purpose. Ask your doctor if you have any questions about why PROCUR has been prescribed for you.

This medicine is available only with a doctor's prescription.

Before you use PROCUR tablets

When you must not take it

Do not take this medicine if:

  • You are allergic to cyproterone acetate ( the active ingredient in PROCUR) or any other ingredient listed at the end of this leaflet.
  • You are pregnant
  • You are breast feeding.
  • You suffer from liver disease (including previous or existing liver tumours).
  • You have a history of jaundice (yellowing of skin and/or eyes) or persistent itching during a previous pregnancy.
  • You have a history of herpes of pregnancy.
  • You suffer from severe depression which has lasted for many months.
  • You have previous or existing blood clots.
  • You have severe diabetes.
  • You have abnormal red blood cells (sickle-cell anaemia).

A liver function test should be performed before treatment.

Male patients: Your doctor may instruct you to have a sperm count recorded before starting treatment to determine whether you are fertile or infertile. There may be a reduction in the overall number of sperm during treatment but it will gradually recover after you have stopped the treatment.

Female patients: Your doctor may perform a thorough gynaecological examination before starting treatment.

Taking other medicines

Tell your doctor if you are taking any other medicines or if you had an allergic reaction to any medicine that you have taken previously to treat your current condition.

If you are diabetic, your doctor may alter the dose of oral antidiabetics or insulin required to treat your diabetes.

Using PROCUR tablets

How much to take

For Men

For treatment of inoperable prostate cancer:
To eliminate the effect of male sex hormones produced by the adrenal glands, the usual daily dose is:

  • After removal of the testicles: 2 100mg tablets once or twice daily.
  • Without removal of the testicles: 2 100mg tablets twice to three times daily.

To reduce the initial increase of male sex hormones in treatment with LH-RH agonists (such as buserelin), the initial dose of PROCUR is100mg tablets twice daily alone for 5-7 days, followed by 100mg twice daily for 3-4 weeks together with an LH-RH agonist.

To eliminate the effect of male sex hormones produced by the adrenal glands in treatment with LH-RH agonists, the usual dose is 100mg once or twice daily.

For Women
For women of childbearing age, the usual dose is 100mg daily from the 1st to the 10th day of the menstrual cycle (=10 days). In addition, your doctor will also prescribe a combined oral contraceptive pill from the 1st to the 21st day of the cycle to provide the necessary contraceptive protection and to stabilise the cycle.

Take the tablets at the same time each day. If more than 12 hours pass from this time, ask your doctor or pharmacist for advice as to how to continue.

After 21 days, there will be a 7-day tablet-free interval during which withdrawal bleeding will occur. If bleeding fails to occur, this may be a sign that you are pregnant. Talk to your doctor immediately.

After there is improvement to your condition, your doctor may lower the dose to 25-50mg daily during the first 10 days of the combined treatment.

In post-menopausal patients or patients who have undergone removal of the womb, PROCUR may be used alone. The usual dose is 25 - 50mg once daily for 21 days followed by a 7-day tablet-free interval.

If you forget to take it

If you miss a dose, just take the next dose when it is due. Do not take extra tablets to make up for missed doses.

Taking your medicine at the same time each day may help you to remember to take it regularly. This is especially important for women of childbearig age as this helps avoid pregnancy. If you have trouble remembering to take your medicine, ask you pharmacist for some hints.
