Why is this medication prescribed?
Bicalutamide is used with another medication (gonadotropin-releasing hormone (GnRH) agonists; such as leuprolide or goserelin) to treat metastatic prostate cancer (cancer that started in the prostate and has spread to other parts of the body). Bicalutamide is in a class of medications called nonsteroidal antiandrogens. It works by blocking the effect of androgen (a male hormone), to stop the growth and spread of cancer cells.
How should this medicine be used?
Bicalutamide comes as a tablet to take by mouth. It is usually taken with or without food once a day, either in the morning or evening. Take bicalutamide at around the same time every day. You should begin taking bicalutamide on the same day you begin injecting the luteinizing hormone-releasing hormone. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take bicalutamide exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Bicalutamide along with the luteinizing hormone-releasing hormone may help stop the growth and spread of cancer cells but does not cure prostate cancer. Continue to take both bicalutamide and the luteinizing hormone-releasing hormone even if you feel better. Do not stop taking these medications without talking to your doctor.
