Avodart

Generic name: Dutasteride
Drug class: 5-alpha-reductase inhibitors

Usage of Avodart

Avodart prevents the conversion of testosterone to dihydrotestosterone (DHT) in the body. DHT is involved in the development of benign prostatic hyperplasia (BPH).

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). Be sure to read the medication guide or patient instructions provided with each of your medications.

Avodart may also be used for purposes not listed in this medication guide.
