Anaphylaxis – A guide to diagnosis, management and follow up

Anaphylaxis is a severe, potentially life threatening allergic reaction which occurs in adults and children. Prompt diagnosis and appropriate acute medical management will prevent fatal anaphylactic episodes. Anaphylactic reactions are IgE mediated responses to foreign antigens to which there has been previous exposure. The foreign antigens commonly implicated in anaphylaxis are foods (particularly nuts), drugs and venoms. Long term management should involve liaison with an immunologist/allergist to identify an underlying cause, provide education for further prevention and where possible offer immunotherapy.
