What Cyproterone Sandoz is used for
This medicine is used to treat cancer of the prostate gland. It can also be used in conjunction 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.
It is also used for the reduction of sex drive in men with sexual deviations.
This medicine is used to treat:
- excessive hairiness (hirsutism)
- androgen-dependent loss of scalp hair (androgenic alopecia)
- oily skin.
It contains the active ingredient cyproterone acetate.
Cyproterone acetate belongs to a group of medicines called anti-androgen hormones.
It works by blocking androgens (e.g. testosterone), which are natural male sex hormones. Androgens 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 Sandoz may slow or stop the growth of cancer.
In women, androgens may increase hair growth, loss of scalp hair and secretion of oil from the sweat glands. By blocking these hormones, Cyproterone Sandoz 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 not addictive.
This medicine is available only with a doctor's prescription.

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, 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 50-300mg (half to three tablets) of Cyproterone Sandoz 100mg.
Your doctor may request that you take Cyproterone Sandoz with other medicines and/or change your dose during treatment.
Reduction of drive in sexual deviations:
The usual starting dose is one tablet of Cyproterone Sandoz 50mg twice daily.
Your doctor may change your dose during treatment.
Your doctor will tell you the dose that you should take and when to start taking Cyproterone Sandoz.
When you start taking Cyproterone Sandoz depends on whether you:
- are of child-bearing age
- have amenorrhea (no menstrual periods)
- have had a hysterectomy (surgical removal of the uterus)
- are post menopausal.
Additionally, your doctor will advise the most appropriate "Pill" for you to take to provide the necessary contraceptive protection and to stabilise your menstrual cycle.
Ask your doctor or pharmacist if you are unsure of the correct dose for you.
They will tell you exactly how much to take.
Follow the instructions they give you.
If you take the wrong dose, Cyproterone Sandoz may not work as well and your problem may not improve.
How to take it
Swallow the tablets whole with a full glass of water after meals.
When to take Cyproterone Sandoz
Take your medicine 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.
How long to take Cyproterone Sandoz
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
Take your dose as soon as you remember, and continue to take it as you would normally.
If it is almost time for your next dose, skip the dose you missed and take your next dose when you are meant to.
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.
Missed Cyproterone Sandoz tablets in women may reduce the effectiveness of treatment and may lead to intermenstrual bleeding.
If you are also taking the "Pill" and more than 12 hours has elapsed from the time Cyproterone Sandoz was due to be taken, note that contraceptive protection may be reduced and thus there is an increased risk of becoming pregnant.
If bleeding fails to occur after a cycle where the "Pill" was missed, you must see your doctor.
Your doctor may need to check whether or not you are pregnant before you can continue treatment.
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) 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 Cyproterone Sandoz. Do this even if there are no signs of discomfort or poisoning.
You may need urgent medical attention.
