Prescriptions for self-injectable epinephrine in emergency department angioedema management

Patients with respiratory symptoms and allergic history were likely to be admitted. Epinephrine use was more frequent in patients with signs and symptoms of oropharyngeal edema. Younger patients and those with tightness/fullness of throat were likely to be prescribed SIE. Further studies are needed to determine who would benefit from epinephrine use and SIE prescription.
