Treatment of allergic reactions to peanut in recent versus initial reaction

Background Although studies suggest underuse of epinephrine in food related allergic reactions, it is not clear whether treatment may differ over time in those who have already had an allergic reaction. We sought to characterize treatment of the most recent allergic reaction to peanut versus the initial allergic reaction. Materials and methods Individuals with an allergist-confirmed peanut allergy were recruited from the Montreal Children’s Hospital and Canadian food allergy advocacy organizations. Data were collected on initial allergic reactions to peanut and most recent reaction to peanut during the year prior to study entry.
