Hello Dr. Rassman. My question is concerning the dosage of finasteride i’ve been taking for the past 7 months. I only split my proscar in half for the first several months (2.5 mg a day), and I believe results have been fairly positive so far (a lot less hair in the shower). What’s concerning me is that I have lowered my dosage back to 1 mg recently. I know that this is the recommended dosage, but could I possibly have hurt the finasteride’s long-term effectiveness by starting at a higher dosage and then lowering it? Thanks.

You did the right thing by bringing the dose to the recommended level. The research on dose suggests that 1mg is as good as 2 or 5mgs. A higher dose of finasteride should not impact future adjustments to the correct dose.
