I understand that you don’t prescribe Dutasteride and that taking it is something one should carefully consider. However, I was wondering if you could answer a question about the half life of the medication. I have read that the half life of Avodart is 5-6 weeks and this got me thinking; if you were to take 3.5mg once a week as opposed to 0.5mg daily, would there be more dutasteride in your system and thus more chance of maximizing its benefits and having side effects? Or, would both dosage methods amount to the same thing?
I do not prescribe it because it is not FDA approved for treating hair loss, there are more sexual side effects with this medication, and the sterility reports are more numerous and maybe irreversible when it happens.
With the long half life, less frequent dosing should be adequate, but there is no dosing information available to guide the doctor on how to prescribe it for treating hair loss. So while it might sound logical to take a larger dose once a week, I don’t know how that plays into side effect risks or safety.
