I too have a six year old dau. who is allergic to antibiotics. Right now she has a raging sinus infection, and the doctors are trying to figure out what to do. She has had hives and serum sickness (twice). Because she has had serum sickness, she is at greater risk for anaphylaxsis. Her half-sister died from anaphylaxsis when she was seven. I am worried sick... isn't anyone doing research in this area?
