NSAIDs can prompt exercise-induced anaphylaxis, shows medically challenging case

NEW ORLEANS - Severe allergic reactions, known as anaphylaxis, are scary, and it can sometimes be hard to determine the cause. A new medically challenging case presented at this year's American College of Allergy, Asthma and Immunology (ACAAI) Annual Scientific Meeting reports a situation in which a non-steroidal anti-inflammatory drug (NSAID) caused an anaphylactic reaction in a female runner. NSAIDs are medicines that are widely used to relieve pain, reduce inflammation, and bring down a high temperature.
"We saw a 40-year-old avid runner in our clinic who had no history of food or medication allergies," says Sebastian Sylvestre, MD, ACAAI member and lead author of the abstract. "She had previously tolerated NSAIDs, and she took naproxen before her marathon training run. By mile four she had developed itching and swelling around her eyes. By mile six she had hives, lightheadedness, difficulty breathing, and vomiting. Her husband brought her to the emergency room for treatment."
The abstract authors note that NSAIDs are capable of both bringing on allergic responses and heightening the reaction in certain individuals.
"The combination of NSAID use and exercise may predispose some people to anaphylaxis," says allergist Taha Al-Shaikhly, MD, ACAAI member and co-author of the paper. "It is important that those who engage in strenuous exercise be mindful of the phenomenon and they know the risks, as well as how to manage any anaphylactic symptoms that might arise in the future during exercise."
