This is from the FAAN (Food, Allergy, Anaphylaxis Network

TABLE 2. Grading of Food-Induced Anaphylaxis According to Severity of Clinical Symptoms

Grade Skin GI Tract Respiratory Tract Cardiovascular Neurological
1 Localized pruritus, flushing, urticaria, angioedema Oral pruritus, oral "tingling," mild lip swelling
2 Generalized pruritus, flushing, urticaria, angioedema Any of the above, nausea and/or emesis x’s 1 Nasal congestion and/or sneezing

3 Any of the above Any of the above plus repetitive vomiting Rhinorrhea, marked congestion,sensation of throat pruritus or tightness Tachycardia (increase >15 beats/min) Change in activity level plus anxiety

4 Any of the above Any of the above plus diarrhea Any of the above,hoarseness, "barky" cough, difficulty swallowing, dyspnea, wheezing, cyanosis Any of the above,dysrhythmia and/or mild hypotension "Light headedness," feeling of "pending doom"

5 Any of the above Any of the above, loss of bowel control Any of the above,respiratory arrest Severe bradycardia and/or hypotension or cardiac arrest Loss of consciousness
All symptoms are not mandatory. The severity score should be based on the organ system most affected, eg, if grade 3 respiratory symptoms are present but only grade 1 GI symptoms, then the anaphylaxis severity score would be "grade 3." Boldface symptoms are absolute indications for the use of epinephrine; use of epinephrine with other symptoms will depend on patient’s history.
