Dutasteride .5mg once a week, Finasteride 1mg 6 days a week?

bmurphy710Jan 23, 2019
I've been taking Finasteride 1mg daily for 10 years. Today a reputable doctor suggested I switch to Dutasteride .5mg every other day, and to stop taking Finasteride. Whereas this is all the Wild West of speculation with these things (and Dutasteride has such long half-life), I'm curious what doctors on here think of instead taking Finasteride 1mg 6 days a week and Dutasteride .05mg once a week? I've read all the studies and plenty of anecdotes. Other than "listen to your doctor", your thoughts?

It’s less relevant how much they block the enzyme as to what the actual LEVELS of DHT are in the scalp. That’s what matters. Finasteride blocks serum DHT 70 % and scalp DHT 40 %. For dutasteride these numbers are 90 % and 55 %. Dutasteride gets rid of DHT better. It potentially has more side eff...

This is certainly worth a discussion with your physician. The long term side effect are not clear and everyone responds differently. Personally, I never prescribe Propecia to anyone of child bearing years.  Alternatives such as PRP, though more expensive in the near term, in and...
