Anaphylactic Reactions
Prevention of Anaphylactic Reactions
Avoiding the allergen is the best prevention. People who are allergic to certain unavoidable allergens (such as insect stings) may benefit from long-term Allergen immunotherapy (desensitization) . For allergen immunotherapy, people are given progressively larger doses of the allergen to try to teach the immune system not to react to that allergen. People who have anaphylactic reactions should always carry a self-injecting syringe ofepinephrine. If they encounter a trigger (for example, if they are stung by an insect) or if they start to develop symptoms, they should immediately inject themselves. Usually, this treatment stops the reaction, at least temporarily. Nonetheless, after a severe allergic reaction and immediately after injecting themselves, such people should go to the hospital emergency department, where they can be closely monitored and given additional treatment as needed. People should also wear a medical alert bracelet with their allergies listed on it.
