Angioedema (facial swelling)

Angioedema is a swelling caused by blood vessels leaking fluid into the tissues. It normally happens on the face, lips, and tongue and can happen with hives (urticaria). Angioedema is not usually dangerous, unless the swelling makes it difficult to breathe.

If you or someone else has angioedema and can't breathe properly, it may be a sign of anaphylaxis. Follow the instructions for anaphylaxis.
