What can cause anaphylaxis?
Extreme allergic reactions vary by individual. Some common triggers include:
Foods (most often peanuts, tree nuts like cashews and walnuts, fish and shellfish, milk, soy and eggs)
Medications (while any medication can cause an extreme allergic reaction, antibiotics including penicillin are one of the most common; aspirin and ibuprofen are other possibilities)
Insect Stings (wasps, yellow jackets, hornets, honey bees, etc.)*
Latex Rubber (and/or other rubber products)
Good to Know
Occasionally even exercise itself can bring on anaphylaxis—especially if a person has eaten a food he or she is sensitive to before working out.
