How long does it take for the lips swelling to go down after a allergic reaction?

In brief: A day or two

Often lips, eyelids and tongue can be a site for angioedema following an allergic reaction.
This is related, but not exactly the same thing as hives (or "urticaria"), and angioedema commonly lasts into the next day.
