If slowly titrated up, my doctor never has seen the SJ type of rash. He has been in the business for a long time, so I tend to take his word for it. Now I have found out a person can get a rash, but this is not the same as one that erupts fron having the Stevens Johnson syndrome. I have found this out from personal experience. Heck, even Tylenol now lists SJ as a possible side effect. So just think of the extremely low odds there.
