In the ED, their vitals/exam are as above.The etiology of this patient’s angioedema is likely ACE-inhibitor/ARB mediated but other bradykinin-mediated (hereditary) angioedema and histamine-induced angioedema are on the differential. Without current imminent airway compromise as patient without stridor, without tachypnea, and without change in O2 saturation. Without evidence of imminent airway compromise as patient is able to verbalize without complications. Lower suspicion for PTA (given no unilateral sore throat with uvula deviation), RPA (given no neck swelling or inability to move neck), Lemierre’s (given no evidence of septic emboli/pneumonia), Ludwig’s angina (given no evidence of floor of the mouth involvement), or mediastinitis (given no crepitus). Hence, will proceed as below.
– Labs/Tests: None
– Imaging: None
– Treatments: Stop taking ACE inhibitor
– Consults: None
– Dispo: Likely discharge with plan to stop ACE inhibitor, return precautions, and close PCP follow-up after a period of brief observation
