Drug trade names include Propecia and Proscar, both products of Merck & Co. (the former is marketed for hair loss in male pattern baldness, and the latter for BPH). There is 1 mg of finasteride in Propecia and 5 mg in Proscar.

Cipla also manufactures finasteride (trade names Fincar and Finpecia), as does Dr. Reddy’s (trade names Finax and Finast), Ranbaxy (trade name Finara), Intas (trade name Finalo), and Aleppo Pharmaceutical (trade name Prosteride), who sell the drug at a significantly lower cost than Merck.
