Other Causes of A Life-Threatening Allergic Reaction (Anaphylaxis)

An exercise-triggered life-threatening allergic reaction (anaphylaxis) is a form of physical allergy with symptoms that include a warm feeling spreading throughout the entire body, itching, and redness of the skin. An exercise-triggered life-threatening allergic reaction (anaphylaxis) is often associated with medications or foods that have been taken prior to or after exercise. Someone with a history of an exercise-triggered life-threatening allergic reaction (anaphylaxis) due to foods should avoid exercising for 4 to 6 hours after eating. Exercise-triggered life-threatening allergic reactions (anaphylaxis) have a higher incidence in people genetically predisposed to developing allergic conditions.

When no triggers for a life-threatening allergic reaction (anaphylaxis) can be identified, a diagnosis of an idiopathic life-threatening allergic reaction (anaphylaxis) is made. If you or your child experience a life-threatening allergic reaction (anaphylaxis) and the cause is unknown, your health care professional will analyze the events and conditions surrounding the reaction so you can try to avoid possible triggers.

Like other forms of life-threatening allergic reactions (anaphylaxis), a case of exercise-triggered or idiopathic anaphylaxis is treated with epinephrine. In an exercise-triggered or idiopathic life-threatening allergic reaction (anaphylaxis), inject the health care professional-prescribed EpiPen^® (epinephrine) or EpiPen Jr.^® (epinephrine) Auto-Injector immediately, then promptly call 911 and seek immediate medical attention.
