I found out something interesting. I was looking up two antibiotics that I am allergic to wanting to find out if they were in the same family. They were ceclor and ciprofloxacin. To my surprise I found that a possible side effect for both was Stevens-Johnson Syndrome. With all the talk about it and lamictal, I somehow associated it only with lamictal. It is amazing how many serious side effects are caused by high use drugs. I wonder what else can cause Stevens-Johnson.
