Dutasteride is used alone or in combination with tamsulosin (Flomax®) to treat men who have symptoms of an enlarged prostate gland, which is also known as benign prostatic hyperplasia (BPH). Benign enlargement of the prostate is a problem that can occur in men as they get older. The prostate gland is located below the bladder. As the prostate gland enlarges, certain muscles in the gland may become tight and get in the way of the tube that drains urine from the bladder. This can cause problems with urinating, such as a need to urinate often, a weak stream when urinating, or a feeling of not being able to empty the bladder completely.
Dutasteride blocks the action of an enzyme called 5-alpha-reductase. This enzyme changes testosterone to another hormone that causes the prostate to grow. As a result, the size of the prostate is decreased. The effect of dutasteride lasts only as long as the medicine is taken. If it is stopped, the prostate begins to grow again.
