Please Clarify The Effectiveness of Smaller Finasteride Doses

Dr. Rassman,

You indicated that 0.5mg of propecia was about 80% as effective as 1 mg. I believe you indicated that Dr. David Whiting informed you of this?

Then, someone posted “0.2mg of Finasteride is Almost As Effective as 1mg?” on September 8th which indicates that 0.2mg (not 0.5) is 80% as effective and you said that was the first you had heard of this report and you would look into it.

Would you verify which is correct. I take 1/2 a pill of propecia (for cost mainly) and I would like to know if it is as effective as 1 whole pill, since according to the FDA studies, 0.2 is 80% as effective as 1 whole.

Thanks

I do not want to confuse you. The official dose of 1mg is what I recommend. Even if Dr. Whiting is correct about the 80% effectiveness of 0.5mgs of finasteride, 80% is not as good as 100%. With regard to the lower doses I published, please note that this was just a posting of information I received to stimulate thought. I would not change my dose to a lower dose, because it would put you at risk for hair loss. With the generic Proscar now available on the market, costs are reasonably in reach for most people.
