Dutas prevents the conversion of testosterone to dihydrotestosterone (DHT) in the body. DHT is involved in the development of benign prostatic hyperplasia (BPH).
Dutas is used to treat benign prostatic hyperplasia (BPH) in men with an enlarged prostate. Dutas helps improve urinary flow and may also reduce your need for prostate surgery later on.
Dutas is sometimes given with another medication called tamsulosin (Flomax).Dutas may also be used for other purposes.
