Anaphylaxis is the most severe form of an allergic reaction and can be life-threatening. Many different allergens and situations can cause anaphylaxis. An anaphylactic reaction can involve different parts of the body. Usually there will be a skin reaction, such as hives or swelling, plus a second organ system involved in the reaction, like the gastrointestinal tract, the cardiovascular system or the airway.
Common allergens that may cause anaphylaxis include:
Rarely, symptoms of anaphylaxis can occur without an allergen being involved or identified. This type of reaction is called an anaphylactoid reaction. Features of anaphylactoid reactions include:
More than 70 percent of children who have anaphylaxis will have respiratory system symptoms, and over 80 percent will have hives or swelling of the deep tissue of the skin, lips or tongue. Your child might experience an anaphylactic reaction in as little as a few seconds after being exposed to the allergen, or the reaction may build over a few hours. The more serious reactions tend to happen quickly. Reactions may come in two phases: an early phase and one that may be delayed for six hours. When the reaction occurs more than two hours after exposure, it tends to be less severe.
Some children may experience anaphylaxis after exercise. Their skin may itch with or without hives, and they may have low blood pressure and difficulty breathing. Eating food such as celery, wheat or shellfish a few hours before exercising may be a trigger for this rare problem.
Anaphylaxis occurs when your child’s immune system creates an antibody called immunoglobulin E (IgE). This antibody is associated in exaggerated immune responses—hypersensitivity or "classic" allergy. If there is an allergic reaction, the immune system’s interaction of the IgE antibody and the allergen causes the allergic symptoms.
Allergy testing, done with the skin prick test after a detailed medical history, can find the substances (allergens) that may have caused your child to make this antibody (IgE) and have this kind of a reaction.
Anaphylaxis is a medical emergency, and your child needs to be treated as soon as possible by taking these steps:
While Benadryl (diphenhydramine) can treat itching due to hives, it will not help treat a life-threatening reaction and should not be used as the only treatment for anaphylaxis. Do not use Benadryl to replace epinephrine. With a life-threatening allergic reaction, do not waste any time looking for diphenhydramine (Benadryl). Go with the epinephrine.
The best management for anaphylaxis is for your child to avoid the allergen. Allergy specialists at Riley at IU Health can help you identify the allergen and how to avoid it. An allergy specialist can also teach you how to give your child epinephrine, including when to use it and what to do once epinephrine is used. Children who experience anaphylaxis should wear a medical alert bracelet.
Your child's allergy specialist will help you with a food allergy emergency plan, both for home and for your child’s school or day care. The allergist has the experience and expertise to guide you through this serious condition. You may also want to consider joining a support group such as Food Allergy Research & Education (FARE) if food is a trigger for your child’s reaction.
