Anaphylaxis:  refers to an exaggerated hypersensitivity reaction to a previously encountered antigen.  A severe reaction may precipitate vascular collapse, leading to systemic shock and, sometimes, death.

Cause:  May results from exposure to sensitizing drugs or other substances.  It may result from such drugs as penicillin (most common), other antibiotics, serums, Vaccines, Injections,  allergen extracts, enzymes, hormones, sulfonamides, local anesthetics, salicylates, and polysaccharides.  The reaction may also result from diagnostic chemicals, foods, Fresh Fruit, Sea Foods, sulfites, insect venom such as Bee Sting and, rarely, a ruptured hydatid cyst.


Usually produces sudden distress within seconds or minutes after exposure to an allergen.  ( a delayed or persistent reaction may occur up to 24 hours later.)  Allergic reaction may be mild to severe depending on the original sensitizing dose of antigen, the amount and distribution of antibodies, and the route of entry and the dose of antigen.
