Dear Dr. Rassman,
I started using Proscar (5 Mg. divided into 2, 1 part daily) about 3 years ago. 6 months ago I added the use of Minoxidil just once daily (every morning), opposed to the recommended 2x daily, since it is only to aid the Proscar. Am I doing the right thing?
The recommended dose of finasteride is 1mg for treating hair loss, sold under the brand name Propecia. Taking 5mg or 3mg or 2mg will not grow more hair, but will produce more negative side effects. Changing doses from 5mg or 2.5mg to 1mg will not likely affect hair growth. Merck’s research has shown that 1mg is as good as a higher dose, so if you are taking a higher dose and then bring it down to the normal 1mg does, there should be no negative effect.
