For diagnosed or strongly suspected anaphylaxis, guidelines emphasize intramuscular epinephrine in the mid-outer thigh as first-line treatment, then calling emergency services, positioning the patient, and observation for recurrence. Second epinephrine doses may be needed per action plan. Antihistamines and inhaled bronchodilators are adjuncts when appropriate — they do not replace epinephrine for shock or airway compromise.

Carry two auto-injectors if prescribed; train family and school staff. Avoid eating trigger foods until your allergist clears a plan — this calculator does not identify allergens.
