Treatment of Severe Angioedema with Laryngeal Edema or Anaphylaxis
Clinical Scenario
This protocol covers severe angioedema presentations — specifically those involving laryngeal edema, anaphylaxis, or symptoms that have not responded adequately to antihistamines. Each of these situations signals a need for prompt escalation beyond first-line antihistamine therapy.
Treatment Approach
Management involves corticosteroid therapy for patients with severe symptoms unresponsive to antihistamines or those with laryngeal edema, with epinephrine reserved for the most critical presentations. The complete structured regimen — including specific agents, sequencing, and all relevant parameters — is available in the full protocol.

- Corticosteroids are indicated for patients with anaphylaxis, laryngeal edema, and severe symptoms unresponsive to antihistamines.
- Patients with severe symptoms, laryngeal edema, or anaphylaxis should receive corticosteroids.
- For patients presenting with anaphylaxis, respiratory distress, or severe laryngeal edema, administer epinephrine intramuscular or subcutaneously in a dose of 0.3 mg every 10 minutes (0.3 ml of 1:1000 dilution).
- Administer intramuscular or subcutaneous epinephrine to patients with respiratory distress.
