Avodart is used to treat benign prostatic hyperplasia (BPH) in men with an enlarged prostate. It helps improve urinary flow and may also reduce your need for prostate surgery later on. Avodart is sometimes given with another medication called tamsulosin (Flomax).
Avodart belongs to a class of drugs called 5-Alpha-Reductase Inhibitors.
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 frequently 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.
