Patient Education

Dutasteride


Dutasteride is used alone or with another medication (tamsulosin [Flomax]) to treat benign prostatic hyperplasia (BPH; enlargement of the prostate gland). Dutasteride is used to treat symptoms of BPH and may reduce the chance of developing acute urinary retention (sudden inability to urinate). Dutasteride may also decrease the chance that prostate surgery will be needed. Dutasteride is in a class of medications called 5-alpha reductase inhibitors. It works by blocking the production of a natural substance that enlarges the prostate.

Tamsulosin


Tamsulosin is used in men to treat the symptoms of an enlarged prostate (benign prostatic hyperplasia or BPH) which include difficulty urinating (hesitation, dribbling, weak stream, and incomplete bladder emptying), painful urination, and urinary frequency and urgency. Tamsulosin is in a class of medications called alpha blockers. It works by relaxing the muscles in the prostate and bladder so that urine can flow easily.
