What Is Angioedema?
3. How Long Does Angioedema Last?
Angioedema usually clears up within 24 to 48 hours of its first appearance, even without prophylactic treatment. There is usually no scarring or permanent discoloration after the reaction has subsided. The condition can become serious, however, if the swelling results in closure of the nasal passageways or throat cavity. Having antihistamines on hand can significantly reduce the impact and duration of these episodes.
Some patients may experience recurring angioedema, or display chronic symptoms. In these cases, consider consulting a certified allergist or an ear, nose and throat specialist (otolaryngologist) who can help determine why your symptoms are continuing. There may be an underlying cause that needs to be addressed with supplemental testing, strategic medical imaging or follow-up care.
