BICALUTAMIDE is used together with a luteinizing hormone releasing hormone (LHRH) analog (eg, goserelin or leuprolide) to treat stage D2 metastatic prostate cancer (cancer that has spread) in men. Bicalutamide belongs to the group of medicines called antiandrogens. It works by blocking the effects of testosterone (a male hormone), which helps stop the growth and spread of cancer cells.
