A retrospective emergency department study of 302 patients presenting with anaphylaxis, 87 (29%) of whom were taking at least 1 antihypertensive medication, found that antihypertensive pharmacotherapy increased the risk of organ system involvement and hospitalization. [30, 31] There was a more than 2-fold increased risk of involvement in 3 or more organ systems when ACE inhibitors, beta blockers, diuretics, or any antihypertensive medications were used. Most of these agents were also associated with an increased risk for inpatient admission. [30, 31]
