Propecia at the 10 Year Mark

Hi Dr Rassman I have a question regarding long term efficacy of Propecia in older men who have been using it for an extended period of time.

I am in my mid fifties and have been using it for 10 years and I’m happy with the results it seems to be maintaining fairly well. However I see posts on other hair sites (by users not doctors) who say it stops working. I tend not to trust some of these people as it sometime seems they are freely expounding personal experience rather than hard facts.

Can you shed some light on this for me?

I’ve written about this before, but if the benefits of this medication eventually becomes less apparent and if you should stop it, then you’ll surely find out if it was still working when you begin to lose more hair. In other words, it is best to continue it even if you think it isn’t working anymore, because it likely is still working and stopping the medication may cause you to lose any hair that it was holding onto.

As an aside, there is great evidence that this medication will reduce the risk of prostate cancer in men over 55 years old.
