What ZOLACOS CP is for
ZOLACOS CP combination therapy is the brand name for packs containing ZOLADEX (goserelin)
3.6mg or 10.8mg subcutaneous implant plus COSUDEX (bicalutamide) 50mg tablets.
ZOLACOS CP is used to treat advanced prostate cancer in men. It is not a cure for
prostate cancer. Bicalutamide tablets can also be used to treat disease flare associated
with previous goserelin therapy.
ZOLACOS CP is a combination pack consisting of an anti-androgen (COSUDEX) medicine
and a Luteinising Hormone Releasing Hormone (LHRH) agonist (ZOLADEX).
Androgens such as testosterone are natural male sex hormones. In some types of prostate
cancer, androgens may help the cancer cells to grow.
LHRH agonists reduce the level of testosterone in men.
ZOLACOS CP interferes with some of the actions of these hormones.
ZOLACOS CP should only be taken by men.
Follow all directions given to you by your doctor.
