Hello Doctor,

Firstly I’d like to thank you very much for maintaining such a very informative blog.

I have read that in cases where 1mg finasteride has lost its “effectiveness” in patients over the years you have prescribed 2mg instead of avodart. In the majority of these cases do you see a halt to hair loss, or no change from 1mg. Thanks for your time.

I haven’t seen much difference in results for those men that take 2mg finasteride from the start compared to those that take the recommended 1mg. I’m still not clear if it helps to take 2mg when 1mg seems to not be as effective as it once was (generally after years of taking it). I occasionally do advocate the double dose for those situations, but there isn’t actual evidence that this helps. There’s been only a small handful of patients that I’ve recommended this to within the past year, too soon to get a follow-up. In other words, there is no objective data on the results of changing the dose.
