Treats Disease/Condition

Uses

Enzalutamide is used to treat men with a certain type of prostate cancer. This type of prostate cancer has not responded to other treatments to lower the male hormone testosterone and has also spread to other parts of the body. This medication belongs to a class of drugs known as anti-androgens (anti-testosterone). It works by blocking the effects of testosterone to slow the growth and spread of prostate cancer. Take this medication regularly to get the most benefit from it. To help you remember, take it at the same time each day.

How To Use
