WHAT IS IN THIS LEAFLET
This leaflet answers some common questions about Cyprostat-100.
It does not contain all the available information. It does not take the place of talking to your doctor or pharmacist.
All medicines have risks and benefits. Your doctor has weighed the risks of you taking Cyprostat-100 against the benefits they expect it will have for you.
If you have any concerns about taking this medicine, ask your doctor or pharmacist.

WHAT CYPROSTAT-100 IS USED FOR
Cyprostat-100 is an anti-androgen medicine. Androgens such as testosterone are natural male sex hormones. In some types of prostate cancer, androgens may help the cancer cells to grow. By blocking these hormones, Cyprostat-100 may slow or stop the growth of cancer.
Cyprostat-100 may 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.
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 CYPROSTAT-100
Follow all directions given to you by your doctor or pharmacist carefully.
They may differ from the information contained in this leaflet.
If you do not understand the instructions printed on the pharmacist label, ask your doctor or pharmacist for help.
How much to take
Your doctor will tell you the dose that you should take. The usual daily dose is 50-300 mg of Cyprostat. Your doctor may request you take Cyprostat with other medicines and/or change your dose during treatment.
Do not alter the dose yourself.
Your doctor will advise you if changing the dose is necessary.
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 Cyprostat-100 tablets may diminish the effectiveness of treatment.
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 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 on 13 11 26 for advice, or go to Accident and Emergency at the nearest hospital, if you think that you or anyone else may have taken too much Cyprostat-100. Do this even if there are no signs of discomfort or poisoning.
You may need urgent medical attention.
WHILE YOU ARE TAKING CYPROSTAT-100
Things you must do
If you are about to be started on any new medicine, remind your doctor and pharmacist that you are taking Cyprostat-100.
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 Cyprostat 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 Cyprostat.
Your doctor will also check your red-blood cell count to ensure you do not become anaemic during treatment with Cyprostat.
Things you must not do
Do not take Cyprostat-100 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 Cyprostat-100 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. Alcohol may prevent Cyprostat from working as well as it should in reducing abnormal sex drive.
Tell your doctor or pharmacist as soon as possible if you do not feel well while you are taking Cyprostat-100.
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.

You may not experience any of them.
Ask your doctor or pharmacist to answer any questions you may have.

- nausea and other gastrointestinal complaints
- decreased sexual drive
- breast pain, change in breast size, breast swelling and/or tenderness
- breast enlargement in men
- hot flushes, sweating
- shortness of breath
If you were fertile before treatment, Cyprostat-100 will normally prevent sperm production. Fertility is usually regained within a few months of discontinuing therapy.
Cyprostat-100 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.
Tell your doctor immediately or go to Accident and Emergency at your nearest hospital if you notice any of the following:
- yellowing of the skin and/or eyes, light coloured bowel motions, dark coloured urine

The above list includes serious side effects that may require medical attention or hospitalisation. Serious side effects are rare.
