1. What Cyprostat is and what it is used for
What is Cyprostat?
Cyprostat is a medicine containing cyproterone acetate.
It is an anti-androgen therapy. It blocks the actions of
male sex hormones (androgens) and reduces the
amount of male sex hormones produced by the body.
What is Cyprostat used for?
Cyprostat is used in men to treat prostate cancer.
This medicine is used:
1. to reduce the possible worsening of the disease
which may occur when you start other treatments
used for prostate cancer
2. for long term treatment of prostate cancer when
surgery or other medicines are not suitable
3. to treat hot flushes which may occur during
treatments with other medicines used for prostate
cancer or following surgery.

2. What you need to know before you take
Cyprostat
Do not take Cyprostat:
R If you have liver diseases (including previous or
existing liver tumours (unless these are due to
secondary cancers caused by prostate cancer),
Dubin-Johnson Syndrome or Rotor Syndrome)
R If you have any type of cancer (except for cancer of
the prostate gland)
R If you have ever been diagnosed with a meningioma
(a generally benign tumour of the tissue layer
between the brain and the skull). You should ask

Several blood tests or checks may be required while
you are taking this medicine:
R liver problems, some of them severe or even fatal,
have been reported with cyproterone acetate
treatment. Your doctor may arrange for you to have
regular liver tests before and during treatment to
monitor this and may stop your treatment if
necessary. See also section 4.
R using medicines such as Cyprostat has very rarely
been linked to the development of benign (nonmalignant) liver tumours and with some forms of
liver cancer (malignant liver tumours). Liver tumours
