Exercise-induced anaphylaxis is a rare syndrome that can take 1 of 2 forms. The first form is food dependent, requiring exercise and the recent ingestion of particular foods (eg, wheat, celery) or medications (eg, NSAIDs) to cause an episode of anaphylaxis. In these patients, exercise alone does not produce an episode, and, similarly, ingesting the culprit food or medication alone does not cause an episode.

The second form is characterized by intermittent episodes of anaphylaxis during exercise, independent of any food ingestion. Anaphylaxis does not necessarily occur during every episode of physical exertion.
