I am alergic to sulfa. My Pc at the vet clinic gave me 2 sripts the other day because the are so swamped alot of times they dont check for things like allergies . Last year she wrote me a script that had sulfa in it I never would have known fortunately the pharmasist that filled that script was from the female clinic and had just seen me in a private consult the week before and remembered me.  I had a stroke? brain bleed 3 years ago so I have to be careful of the kind of meds I take no decongestion meds and because of my allergy nothing with sulfa in it.so if someone could please tell me if Pseudoephedrine has sulfa in it or not I would really apprecite it
