Consumer Medicine Information

What is in this leaflet

This leaflet answers some common questions about CYPROTERONE AN.

It does not contain all of the available information. It does not take the place of talking to your doctor or pharmacist.

All medicines have benefits and risks. Your doctor has weighed the risks of you taking CYPROTERONE AN against the benefits they expect it will have for you.

If you have any concerns about taking this medicine, ask your doctor or pharmacist.

Keep this leaflet with the medicine. You may need to read it again.

What CYPROTERONE AN is used for

CYPROTERONE AN is an antiandrogenic hormone medication.

Androgens such as testosterone are natural male sex hormones. 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.

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.

Your doctor and pharmacist may have more information on medicines to be careful with or avoid while taking this medicine.

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. 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.

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 CYPROTERONE AN 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 (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.

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.

Side Effects

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.

Do not be alarmed by the following lists of side effects. You may not experience any of them.

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

Tell your doctor or pharmacist if you notice any of the following and they worry you:

  • depressive mood
  • nausea and other gastrointestinal complaints
  • breast pain, change in breast size, breast swelling and/or tenderness
  • breast enlargement in men

If you were fertile before treatment, CYPROTERONE AN will normally prevent sperm production in men. In men, fertility is usually regained within a few months of discontinuing therapy.

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.

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
  • severe upper abdominal pain

After taking CYPROTERONE AN

Storage

Keep your tablets in the pack until it is time to take them. If you take the tablets out of the pack, they may not keep well.

Keep your tablets in a cool dry place where the temperature stays below 30 °C.

Do not store CYPROTERONE AN or any other medicine in the bathroom, near a sink, or on a window-sill.

Do not leave it in the car. Heat and damp can destroy some medicines.

Keep it where children cannot reach it. A locked cupboard at least one-and-a-half metres above the ground is a good place to store medicines.

Disposal

If your doctor tells you to stop taking CYPROTERONE AN, or your tablets have passed their expiry date, ask your Pharmacist what to do with any that are left over. Return any unused medicine to your pharmacist.
