While the incidence of ACEI-induced angioedema is low, ACEI use will continue to increase its frequency. Emergency physicians and otolaryngologists should play a key role in identifying patients with angioedema associated with ACEIs. ⋯ The physician must be aware of the fact that a moderate swelling can rapidly develop to a massive swelling, which requires an intubation or even a coniotomy. Thus, in any of these cases, the patient should be observed at least for 24 hours in the clinic or until the edema subsided almost completely.
