Alrite, I just finished 5 months on Accutane and around the 4th month I noticed that I was slowly losing my sex drive (libido). Obviously no sex drive means no erection, unless your on Viagra! So my derm tells me that ED and loss of libido are both documented as very rare side effects of Accutane. I was wondering why he didn't tell me this before? In any case, its already too late. Apparently, he says it shouldn't be permanent but I've been reading other guys posts on this issue and none really get back to 100%. So just beware. For the guys that have experience with this...your feedback would be greatly appreciated.
