1. WHAT ZOLADEX IS AND WHAT IT IS USED FOR
Zoladex contains a medicine called goserelin. This belongs to a group of medicines
called ‘LHRH analogues’.
Zoladex is used to treat prostate cancer. It works by reducing the amount of
‘testosterone’ (a hormone) that is produced by your body. Zoladex is a long-acting
form of Zoladex and it is given every 12 weeks.
