What Cosudex is for
COSUDEX 50 mg is used in combination with other medicines to treat advanced prostate
cancer.
COSUDEX 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. COSUDEX interferes with some of the actions of these hormones.
COSUDEX should only be taken by men.
Follow all directions given to you by your doctor.
They may differ from the information in this leaflet.
Your doctor may prescribe this medicine for another use. Ask your doctor if you want
more information.
COSUDEX is not addictive.
