Other problems to be considered in diagnosing potential anaphylaxis include the following:

  • Vasodepressor (vasovagal) reaction (probably the most common masquerader)

  • Globus hystericus

  • Hereditary angioedema

  • Other forms of shock (ie, hypovolemic, cardiogenic, septic)

  • Flushing syndrome, including red man syndrome (vancomycin), pancreatic polypeptide tumors, postmenopausal patient, ethanol-induced, autonomic epilepsy

  • Monosodium glutamate poisoning

  • Scombroid fish poisoning

  • Capillary leak syndrome

  • Myocardial dysfunction

  • Foreign body aspiration (young children, especially)

  • Poisoning, acute

  • Neurologic (stroke, seizure)

Nonorganic disease, including panic attack, hyperventilation, vocal cord dysfunction syndrome, somatoform anaphylaxis
