A member asked:

I have taken bactrim (sulfamethoxazole and trimethoprim) many times w/out incident. am i at risk for stevens johnson each time i take it or only if i have sulfa allergy?

A doctor has provided 1 answer

Each time: Everyone is at risk of having sjs from sulfa drugs and other drugs carry that risk too. These reactions are idiosyncratic and are not predictable.
