Proscar, also known by its generic name finasteride, is a medication used to shrink an enlarged prostate in adult men. This drug is used in a treatment plan with other medications to reduce symptoms of benign prostatic hyperplasia (BPH). BPH is a condition that affects older men and it can cause uncomfortable urinary symptoms as well as bladder, urinary tract or kidney problems.

How does Proscar work?

Finasteride blocks the conversion of testosterone and the hormone dihydrotestosterone. Dihydrotestosterone is partly responsible for making the prostate enlarge, so this drug reduces the amount of this hormone, which prevents the hormone from enlarging.
