Dr. Rassman, I’m 35 and I’m considering taking Propecia. Do I assume for most patients taking Propecia, that after being on the drug for an extended period of time (four, five, six years perhaps?) that it’s normal for Propecia to eventually lose it’s effectiveness or level off somewhat? Also, as a Propecia user yourself, did you experience any hair shedding when you started the drug and do you think this is something new users should be concerned about? Your site is very helpful. Thanks for taking the time.
When I started Propecia (finasteride 1mg), I did not experience any shedding. Shedding is very rare, but when it occurs it does stop in a couple of months. Over time, the Propecia does not lose effectiveness, but as hair loss is a progressive process, it eventually overtakes the ability of Propecia to stop the loss process.
