I recently doubled my dose and was again told to look out for a rash. Didn't expect it to happen, though, since I have been on it for nearly two years and have not had any problems.
SJS sounds horrible! Glad you were on top of it and stopped it before it got any worse. What happened to your family member is like one of those horror stories.

It's so upsetting that these meds which are supposed to make us better can actually cause us a lot more harm.
Fortunately my rash turned out to just be due to the sunburn. I think I caused it myself by scratching the itchy sunburned areas. Aloe vera worked wonders.
