  1. All symptoms are not mandatory. The severity score should be based on the organ system most affected, e.g., if grade 3 respiratory symptoms are present but only grade 1 GI symptoms, then the anaphylaxis severity score would be “grade 3”. Boldface letters are absolute indications for the use of epinephrine; use of epinephrine with other symptoms will depend on patient’s history
