Dear Doc,

I have been on propecia for three months. After my pills ran out I got a little lazy and didnt renew my perscription. In fact I havent been on the drug for almost four months. During this time I noticed considerable shedding, which I guess, reading from your blog, is to be expected. My question is though, does the shedding mean that the drug was actually working? Or is it some abnormal side-effect?

FYI I am 22 and baldness runs in my family.

Sounds like you figured it out. Please be smart and go back and stay on the drug. Discuss this with your prescribing physician.
