When acute anaphylaxis is suspected, immediate medical attention should be seeked. Patients who have been prescribed self-injected adrenaline (epinephrine) should use it if they have developed symptoms suggestive of anaphylaxis (always according to their personalized management action plan).

Long term management is crucial in these patients. This means that they should be urgently referred to an allergy unit in order to assess possible causes and to be trained on the recognition and management of the acute anaphylaxis.
