b. Reduced blood pressure or associated symptoms of end-organ dysfunction (e.g., hypotonia, syncope, incontinence) | ||
c. Severe gastrointestinal symptoms (e.g., severe crampy abdominal pain, repetitive vomiting), especially after exposure to non-food allergens | ||
Criteria 2 | Acute onset of hypotension or bronchospasm or laryngeal involvement after exposure to a known or highly probable allergen (minutes to several hours), even in the absence of typical skin involvement | |
