Dutasteride prevents the conversion of testosterone to dihydrotestosterone (DHT) in the body. DHT is involved in the development of benign prostatic hyperplasia (BPH).
Dutasteride is used to treat benign prostatic hyperplasia (BPH) in men with an enlarged prostate. Dutasteride helps improve urinary flow and may also reduce your need for prostate surgery later on.
Dutasteride 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.
