What CYPROTERONE AN is used for
CYPROTERONE AN is an antiandrogenic hormone medication which has several different uses.
Androgens such as testosterone are natural male sex hormones which are also produced, to a slight extent, in females.
In men, androgens may help cancer cells to grow in some types of prostate cancer. By blocking these hormones, CYPROTERONE AN may slow or stop the growth of cancer. CYPROTERONE AN may also be used in combination with other medicines 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.
CYPROTERONE AN is also used to reduce abnormal sex drive in men.
In women, androgens may increase hair growth, loss of scalp hair and secretion of oil from the sweat glands. By blocking these hormones, CYPROTERONE AN may slow or stop excessive hairiness, loss of scalp hair, acne, oily skin and dandruff.
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.
This medicine is available only with a doctor’s prescription.

How to take CYPROTERONE AN
Follow all directions given to you by your doctor and pharmacist carefully. They may differ from the information contained in this leaflet.
If you do not understand the instructions on the pack, ask your doctor or pharmacist for help.
How much to take
Your doctor will advise of the most suitable dose for you to take.
Do not alter the dose yourself. Your doctor will advise you if changing the dose is necessary.
The usual daily dose is 50-300 mg of CYPROTERONE AN. Your doctor may request you take CYPROTERONE AN with other medicines and/or change your dose during treatment.
Reduction of abnormal sex drive
Generally treatment is started with 50 mg of CYPROTERONE AN twice daily and may be increased to 100 mg twice daily or three times daily before reducing gradually to the lowest effective dose. Your doctor may change your dose during treatment.
If you are of childbearing age, you should
your tablet taking on the 1st day of your cycle (= 1st day of bleeding). If you have no menstrual periods (amenorrhoea) your treatment can start immediately. In this case, the first day of treatment is to be regarded as the 1st day of the cycle.
Starting from day 1 take 50-100 mg (as advised by your doctor) of CYPROTERONE AN daily from the 1st to the 10th day of the cycle (= for 10 days). Additionally, your doctor will advise the most appropriate contraceptive for you to take to provide the necessary contraceptive protection and to stabilise your cycle.
If you are postmenopausal or have had a hysterectomy, CYPROTERONE AN may be administered alone. The usual dose is 25-50 mg of CYPROTERONE AN once daily for 21 days, followed by a 7-day tablet-free interval.
Shortness of breath may occur at high doses.
How to take it
Swallow the tablets whole with some liquid after meals.
When to take it
Take your medicine after meals at about the same time each day. Taking it at the same time each day will have the best effect. It will also help you remember when to take it.
Missed CYPROTERONE AN tablets may diminish the effectiveness of treatment and may lead to breakthrough bleeding in women.
How long to take it
Continue taking your medicine for as long as your doctor tells you.
This medicine helps to control your condition, but does not cure it. It is important to keep taking your medicine even if you feel well.
If you forget to take it
If it is almost time for your next dose, skip the dose you missed and take your next dose when you are meant to. Otherwise, take it as soon as you remember, and then go back to taking your medicine as you would normally.
Do not take a double dose to make up for the dose that you missed. This may increase the chance of you getting an unwanted side effect.
If you are also taking an oral contraceptive and more than 12 hours has elapsed from the time CYPROTERONE AN was due to be taken, note that contraceptive protection in this cycle may be reduced and thus there is an increased risk of becoming pregnant.
If you are not sure what to do, ask your doctor or pharmacist.
If you have trouble remembering to take your medicine, ask your pharmacist for some hints.
If you take too much (overdose)
Immediately telephone your doctor, or the Poisons Information Centre (telephone 13 11 26), or go to Accident and Emergency at the nearest hospital, if you think you or anyone else may have taken too much CYPROTERONE AN.
Do this even if there are no signs of discomfort or poisoning. You may need urgent medical attention.
Keep telephone numbers of these places/services handy.
While you are taking CYPROTERONE AN
Things you must do
If you are about to start taking any new medicines, tell your doctor and pharmacist that you are taking CYPROTERONE AN tablets.
Tell any other doctors, dentists, and pharmacists who treat you that you are taking this medicine.
Keep all of your doctor's appointments so that your progress can be checked. Your doctor may do some tests from time to time to make sure the medicine is working and to prevent unwanted side effects.
Your doctor will check your liver function during treatment with CYPROTERONE AN and whenever any symptoms or signs suggesting liver problems are observed.
If you have diabetes, your doctor will monitor you to ensure that you receive the appropriate dose of oral antidiabetic or insulin whilst taking CYPROTERONE AN.
Your doctor will also check your red-blood cell count to ensure you do not become anaemic during treatment with CYPROTERONE AN.
If you are a female taking an oral contraceptive during treatment, tell your doctor if your period does not occur during the tablet-free/ placebo interval. Your doctor may need to check whether you are pregnant before you can continue treatment.
If you are a male taking CYPROTERONE AN to reduce abnormal sex drive, you should consider additional measures such as therapy or counselling in order to take advantage of the period of reduced drive. These measures may assist in achieving personal and social re-orientation.
Things you must not do
Do not take CYPROTERONE AN to treat any other complaints unless your doctor tells you to.
Do not give your medicine to anyone else, even if they have the same condition as you.
Do not stop taking your medicine or lower the dosage without checking with your doctor. If you stop taking it suddenly, your condition may worsen or you may have unwanted side effects.
Things to be careful of
Be careful driving or operating machinery until you know how CYPROTERONE AN tablets affects you. This medicine may cause tiredness and can impair the ability to concentrate. If you have any of these symptoms, do not drive, operate machinery or do anything else that could be dangerous.
Be careful when drinking alcohol while you are taking this medicine. If you drink alcohol, tiredness and the ability to concentrate may be worse. The effectiveness of CYPROTERONE AN to reduce abnormal sex drive can also be diminished under the influence of alcohol.
Tell your doctor or pharmacist as soon as possible if you do not feel well while you are taking CYPROTERONE AN.
All medicines can have side effects. Sometimes they are serious, most of the time they are not. You may need medical treatment if you get some of the side effects.

If you were fertile before treatment, CYPROTERONE AN will normally prevent sperm production in men and ovulation in women. In men, fertility is usually regained within a few months of discontinuing therapy. The long term effects on female fertility are not known.
In men CYPROTERONE AN will also normally result in the inability to get or maintain an erection (impotence). This ability is usually also regained within a few months of discontinuing therapy.
The above includes the more common side effects of your medicine.
