Flutamide

Why this is used

Flutamide is used together with a luteinizing hormone-releasing hormone agonist (LHRH; a type of hormonal injection such as leuprolide [Lupron, Eligard], goserelin [Zoladex], or triptorelin [Trelstar]) to treat certain types of prostate cancer. Flutamide is in a class of medications called nonsteroidal antiandrogens. It works by blocking the effects of androgen (a male hormone) to stop the growth and spread of cancer cells.

How to take it

Flutamide comes as a capsule to take by mouth. It is usually taken with or without food every 8 hours (three times a day.) Take flutamide at around the same times every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take flutamide exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor. Continue to take flutamide along with the LHRH agonist treatment even if you feel well. Do not stop taking either medication without talking to your doctor. Ask your pharmacist or doctor for a copy of the manufacturer's information for the patient.
