The severity of an allergic reaction could be unpredictable. The majority of the allergic reactions present with mild to moderate symptoms and signs and they do not progress to anaphylaxis (even in children with history of anaphylaxis).
There are groups of patients at an increased risk of anaphylaxis and required to carry AAIs e.g. children who have a history of anaphylaxis in the past (breathing difficulty or signs of hypotension), severe asthma, or if they live in a remote location which would result in medical help being delayed.
A risk assessment is completed by a healthcare professional upon diagnosis. Spare, back-up AAI’s can improve preparedness for a potential first time severe allergic reaction if pupils have been given authorisation for their use.
