Propecia Produces PMS in Men?

I feel that ever since I started Propecia, I was into wide fluctuations of emotions, mood swings, and hot flashes as if I was in Premenstrual Syndrome (PMS). I am a physician so I know what I am talking about. I stayed on Propecia for 6 months and could not take it anymore, so I stopped about 3 months ago. These symptoms went away within a week and have not returned since. When I saw this website, I thought you might be able to give me insights into this unusual symptom not reported in the literature I reviewed. Any thoughts? The website is well done, thanks.

There are effects of Propecia on estrogen and estradiol production, so what you are describing may ring true to this hormone’s action or inaction. See: High Estrogen in Men
