To prevent anaphylaxis, people who have a reaction must identify the trigger and then avoid future exposure. This is done by a trained allergist taking a good history, doing allergy tests and occasionally by doing specific very controlled challenges.
People at risk for anaphylaxis must be taught to immediately recognise the early signs of anaphylaxis. They must be provided with an emergency action plan that describes the signs of a mild-moderate attack versus a severe anaphylactic attack, and taught the correct response for either possibility.
- People at risk of anaphylaxis must wear a Medic Alert disc identifying them as being at risk and also detailing their own unique trigger factors
- Patients must carry emergency treatment with them at all times and know how to inject themselves with adrenaline for a severe attack
