Please stop: the medicine for now, review what happened with your doctor, yes it can happen: you can develop an allergic reaction to a medicine even after several times using it, rare though, but can happen, also it can be a reaction to an inactive ingredient in the generic form, check with your doctor for an alternate medication, if you have to take bactrim (sulfamethoxazole and trimethoprim) and no alternative, then see an allergist, good luck
