'''Anaphylaxis''' is an [[acute (medical)|acute]] [[circulation|systemic]] (multi-system) and severe Type I Hypersensitivity [[allergy|allergic]] reaction in humans and other [[mammal]]s.  The term comes from the Greek words ''ana'' (against) and ''phylaxis'' (protection).<ref>"Anaphylaxis." Etymology. ''Oxford English Dictionary''. http://dictionary.oed.com.</ref> Anaphylaxis occurs when a person or animal is exposed to a trigger substance, called an ''[[allergen]],'' to which they have already become sensitized. Minute amounts of allergens may cause a life-threatening anaphylactic reaction. Anaphylaxis may occur after ingestion, skin contact, injection of an allergen or, in rare cases, inhalation.<ref>"Anaphylaxis." Health. 17 January 2002 .

The [[Asthma and Allergy Foundation of America]] advises patients prone to anaphylaxis to have an "allergy action plan" on file at school, home, or in their office to aid others in case of an anaphylactic emergency, and provides a free

[http://www.aafa.org/display.cfm?id=4&sub=81&cont=392 "plan"] form anyone can print. Action plans are considered essential to quality emergency care. Many authorities advocate immunotherapy to prevent future episodes of anaphylaxis.[http://www.acaai.org/public/patients/factSheet.htm "allergy fact sheet"] Immunotherapy with Hymenoptera venoms is especially effective and widely used throughout the world and is accepted as an effective treatment for most patients with allergy to bees, wasps, hornets, yellow jackets, white faced hornets, and fire ants.

Beta-blockers may aggravate anaphylactic reactions and interfere with treatment.
