Propecia Gives Me More Erections and a Higher Sex Drive

I noticed that for the 3 weeks I was on Propecia, I have more frequent erections, strong ones and a higher sex drive. Is this normal? I really don’t mind the side effect and my wife actually likes the change!

I actually hear about this from about 10% of my patients on Propecia. This results from a raise in testosterone, reported as high as 18% on average. The testosterone levels generally do not stay higher than normal and will eventually come back down to normal. Tell your wife… well, maybe don’t say anything. Ha!
