Anaphylaxis is typically triggered by exposure to specific substances or factors. Common triggers include certain foods, medications, food additives, radiocontrast agents used in medical imaging, bee venom, biological drugs, and latex. Among food allergens, peanuts, tree nuts, milk, and shellfish are the most frequently implicated. Key medication triggers often include nonsteroidal anti-inflammatory drugs (NSAIDs) and beta-lactam antibiotics. It is important to note that any medication carries a potential risk of inducing anaphylaxis in predisposed individuals. Additionally, rarer triggers such as exercise, pollen, red meat, seminal fluid, and vaccines can also provoke an anaphylactic reaction.
