Anaphylaxis prevalent but patients unprepared


Anaphylaxis is more prevalent than once thought, occurring in nearly 1 out of every 50 Americans. Of individuals self-reporting a previous anaphylactic episode, only 11% said they used epinephrine to treat their symptoms and 10% reported calling for emergency services. Comparatively, up to one-third of patients cited using an antihistamine to treat symptoms.
