I was on it for maybe 2 weeks. A few days in I noticed a sort of numbing of my weenie. Needless to say I stopped taking it shortly thereafter and things went back to normal. I don't want to know what would've happened had I continued for a long duration.

I am not sure. I used to apply an external lotion Finasteride.

Maybe I will straightaway refuse if a doc prescribes Finasteride pills to me.
