I was prescribed 1 mg finasteride to be take M/W/F by a dermatologist. I used the medication for 3 weeks but stopped because of an intense burning sensation on my penis. are these normal side effects? Have any of you ever experienced this? The burning was pretty uncomfortable, it actually hurt. The sensation stopped 3-4 days after I stopped taking the finasteride. What do you guys think? Should I give finasteride. another try??
