I shed hair while on it, but that seemed to have stopped once off... The main side effect that lingered for years afterwards was an intestinal issue. Mainly in the mornings. I'd wake up most every morning feeling like my insides were tied in a knot. It would start to fade after I took my morning piss and I rarely would notice it during the day. Took years for it to go away. Probably 4 or 5 to really start fading. It's been 7 years since I've taken it and very seldom does it happen now. It wasn't completely unbearable, but I noticed it enough for years to know that Accutane may have been a mistake. Could have done other things to me that I'm not aware of. I only took 1 six month round. Would have never touched it again even if my acne had come back.
While on it, the main side effects were the intestinal thing as previously explained, hair shedding, mood swings and VERY dry skin and lips. The only time I ever actually considered committing suicide was while on Accutane. Although I can't blame the drug fully.. I was at the bottom of the barrel mainly because of my skin issues at the time.
Also, I never went to a doctor about the intestinal issue.. I just toughed it out for years. I figured they would prescribe me another drug to alleviate the symptoms. After Accutane I did not trust taking another medication that solves one problem and creates 3 others.
