Causes
Life Threatening Causes
Any of the factors precipitating anaphylaxis can be life threatening.
- Food: Peanuts, Tree nuts, walnuts, pecans, milk, soyabean, wheat, eggs, pistachios, filberts, cashews, almonds, etc.
- Shellfish: crab, crayfish, prawns, shrimp, lobster, etc.
- Medications: Penicillin, Sulfa antibiotics, Allopurinol, and many other drugs
- Diagnostic materials: IV contrast material and dyes
- Insect venom: including bees, wasps, ants
- Natural rubber latex
- Idiopathic/ Coital anaphylaxis
Diagnostic Criteria

♦ Acute onset of a reaction (mins to hours) involving skin, mucous membrane or both. Additionally including atleast one of the following:
- Respiratory compromise or
- Cardiovascular compromise/Evidence of end organ dysfunction.
♦ 2 or more of the following in a patient known to come in contact with an established allergen:
- Skin/mucosal tissue involvement
- Respiratory compromise
- Reduced blood pressure
- Gastrointestinal manifestations
♦ Reduced blood pressure after exposure to a known allergen.
