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.

Get Propecia for as low as $349.98, which is 20% off the average retail price of $439.00 for the most common version, by using a GoodRx coupon.
