What are common causes of anaphylaxis?

Anaphylaxis is a severe and potentially life-threatening allergic reaction that typically occurs in response to specific triggers. One of the most common causes of anaphylaxis is allergic reactions to foods and medications. Foods such as peanuts, tree nuts, fish, shellfish, milk, eggs, and soy are well-known allergens that can provoke an anaphylactic response. Similarly, certain medications like penicillin and non-steroidal anti-inflammatory drugs (NSAIDs) can also lead to such reactions.

When an individual encounters a known allergen, their immune system may overreact, leading to the release of chemicals such as histamine, which causes symptoms such as swelling, hives, difficulty breathing, and a drop in blood pressure. Recognizing these triggers and understanding their role in anaphylaxis is crucial for timely treatment and management, including the use of epinephrine to counteract the reaction.
