I have recently started taking finasteride. Although, in order to save money, I buy them in the 5mg size. I try to cut them into 4 pieces as equally as possible, but considering the shape of the pill(triangular), this is not always an easy task. My question is: Are there any problems I will run into by sometimes taking a little more than 1.25mg and sometimes a little less than 1.25mg, especially in regards to the rebound effect. More specifically, does my body/scalp get use to taking the amount that is over 1.25mg, therefore not recieving enough when I take a little less than 1.25mg and therefore, contributing to hair loss.
Small variations in the dose should not be a problem, provided that you average 1-1.25mgs per day. That is why the drug company makes Propecia, as it is exactly the correct recommended dose of 1mg. No cutting required with Propecia, but you are going to be paying a premium over the generic 5mg finasteride.
