I took Accutane precribed by my dermatologist. I took 40 mg ed. At the beginning of the 3rd month I started to get blurry vision, headaches, and had to come home from work because of nuasea(spelling?). I got home and threw up. This happened 2 or 3 more times with just the blurry vision and headaches.
I knew these where side effects from Accutane because of brain swelling. I just told myself it was my tooth needing a filling because the headache would be on the side of my face. I wanted to get rid of the acne so bad I kept taking it knowing it was probably the Accutane causing it, but I could deal with a bad headache ever so often.
I stopped taking it at the end of my 3rd month because my vision got bad. It's now two months later and I still have problems with my vision and probably need contacts. Accutane can cause permanent damage to the optic nerve. I'll find out at the beginning of the year when my insurance starts over and I go to the eye doctor.
Lesson learned- Don't be a dumbass like me and keep on taking the stuff if you are feeling any side effects from it. The stuff works great. That's why I kept taking it b/c everything else I tried didn't work. If you do decide to take it be careful.
Good luck!
