Angioedema – Symptoms, Causes and Treatment

Angioedema is an allergic reaction closely related to ANAPHYLAXIS characterized by hives (large, welldefined swellings) that appear suddenly in the skin and larynx. The swellings may last several hours (or days, if untreated).

What causes Angioedema?

The most common cause is a sudden response to certain foods (such as strawberries, peanuts, tree nuts, eggs, or seafood); less often it occurs in response to a medication (especially PENICILLIN), insect stings, snake bite, infection, emotional stress, exposure to animals, molds, pollen, or cold.
