i have read the finasteride studies for alopecia. in the pre-clinical study, 0.25mg of finasteride was shown to reduce DHT at the same rate as 1mg. when the clinical studies were done, the dosage used was 1mg. less than that was never looked at with regard to actual clinical outcome. what is your opinion on extrapolating this info to clinically use 0.25mg per day? the purpose of this would be to get efficacy and reduce potential longer term complications. thanks.
I spoke with Dr. David Whiting, an expert on Propecia, some time ago and he informed me that finasteride 1mg and greater has equal value. A dose of 0.5mg is 80 percent as effective and a dose of 0.25 is less effective again. There is value at the lower dose, but if there are no side effects, taking less than the best optimal dose has no basis.
I’ve answered a similar question here — 0.2mg of Finasteride is Almost As Effective as 1mg?
