I got my first Xolair injection on April 17th for hives and my allergies that didn’t respond to allergy pills. Ever since the first injection, it’s been so hard for me to stomach pizza (was not an issue before). For reference, I have a GI reaction to shellfish (more than likely will turn anaphylaxis later)- and the reaction is the same. I can’t find anything online supporting Xolair causing new intolerances/allergies… has anyone else had a similar issue while on Xolair?
