Finasteride (
Proscar, Propecia) is an inexpensive drug used for the treatment of
hair loss and
benign prostatic hyperplasia (
BPH). Proscar (finasteride 5 mg) is used to treat BPH, and Propecia (finasteride 1 mg) is used for hair loss. Generic finasteride is covered by most Medicare and insurance plans for BPH, but not for hair loss, so pharmacy coupons may be lower.
