What is anaphylaxis?

Anaphylaxis is a severe systemic allergic reaction resulting from exposure to allergens that is rapid in onset and can cause death.1-3 Anaphylaxis is triggered by a wide range of allergens including but not limited to foods, insect stings and bites, medications, and latex. While less common, anaphylactic reactions can also be triggered by exercise.4-6 When no triggers for an anaphylactic reaction can be identified, a diagnosis of idiopathic anaphylaxis is made.5 Anaphylaxis occurs most commonly in the community setting, in the absence of a health care professional, so it is essential for patients at risk for anaphylaxis to be identified and prepared in the event of an emergency.5,7 Anaphylaxis poses serious health consequences if at-risk patients are not identified and prepared.1 As such, anaphylaxis should be treated as a preventable, long-term disease for at-risk patients.1
