Red flags & when to go in person for Angioedema (Mild) - Triage

Audience: adult

Angioedema is swelling beneath the skin, often around the eyes, lips, or throat. Mild angioedema usually causes swelling without serious symptoms and can often be managed with telemedicine guidance. However, some signs mean you should seek in-person care immediately. These include difficulty breathing, swelling of the tongue or throat, or sudden worsening of symptoms. Telemedicine can help assess mild cases, provide advice on symptom management, and guide you on when to get urgent care. It cannot replace emergency treatment for severe or rapidly progressing angioedema. If you experience any red flags, go to the nearest emergency department or call emergency services. Always share your full medical history and current medications during a tele-visit to help healthcare providers give the best advice. This guide helps you understand when telemedicine is appropriate and when in-person care is necessary for angioedema.
