Ask your Dr. to prescribe you Proscar. It has 5mg of finasteride and cost about the same. And, sometimes your ins. will cover proscar bc it is for the prostate.
I get my finistride 100- 5mgs for $200. each tablet gets cut into 4 equal pieces. I take a 1¼ dose everyday. If you want Avodart ,you might try your Dr. and insurance company. If you have enlarge prostate ,you could get away with that. They claim that hair will grow back.
