What is a key preventive step to reduce risk of future anaphylaxis?

• A. Epinephrine pre-treatment
• B. Allergen identification
• C. Immunoglobulin therapy
• D. Avoidance of all allergens

Answer: (B)

Preventing future anaphylaxis hinges on pinpointing the trigger. By taking a careful history and using tests such as skin testing or serum-specific IgE, you identify whether the reaction is to foods, insect venom, medications, or another allergen. Knowing the culprit lets you create a targeted avoidance plan and teach the patient how to avoid exposure, read labels, and carry an epinephrine auto-injector for emergencies. Prophylactic epinephrine isn’t used routinely to prevent every exposure, and immunoglobulin therapy isn’t a standard preventive measure for most anaphylaxis triggers. Absolute avoidance of all possible allergens isn’t practical. Targeted identification of the trigger is the most effective way to reduce future risk.
