This medication is used in men to treat the symptoms of an enlarged prostate (benign prostatic hyperplasia-BPH). It works by reducing the size of the enlarged prostate. This helps to relieve symptoms of BPH such as difficulty in beginning the flow of urine, weak stream, and the need to urinate often or urgently (including during the middle of the night). It may also reduce the need for surgery to treat BPH.Dutasteride is not approved for prevention of prostate cancer. It may slightly increase the risk of developing a very serious form of prostate cancer. Talk to your doctor about the benefits and risks.This medication should not be used by women or children.
