Treatment for ACE inhibitor angioedema

ACE inhibitor angioedema is deeper swelling beneath the skin or lining of the mouth and airway. It may occur without hives or itch, so the absence of a rash does not make it harmless. The reaction can appear soon after starting treatment or after the medicine has been used for a long time. A clinician will assess the airway, review medicines, and distinguish this pattern from hives, allergy, infection, or another cause of skin swelling.

If swelling is suspected, seek urgent medical advice and tell the team the exact ACE inhibitor and time of the last dose. Do not restart it unless a clinician specifically directs you. A replacement blood-pressure medicine may be selected by the prescriber. Antihistamines or corticosteroids may be used in some situations, but they do not replace airway assessment and may not address the mechanism of ACE inhibitor angioedema. Keep a record of the reaction for future healthcare visits.

Call emergency services immediately for tongue or throat swelling, trouble breathing, noisy breathing, difficulty swallowing, drooling, voice change, faintness, or rapidly increasing facial swelling. Do not drive yourself if breathing or swallowing is affected. Even swelling limited to the lips or face needs prompt clinical advice because it can progress unpredictably.

Ask which medicine caused the reaction, what blood-pressure option can replace it, whether you need an emergency plan, which symptoms should trigger emergency care, and how the reaction should be recorded in your medical notes.
