What is Angioedema?

Angioedema is a reaction that sometimes happens along with hives. It is swelling under your skin. It often affects your eyes and lips, and sometimes your genitals, hands and feet.

Causes of Angioedema

Hives pop up when skin cells release a substance called histamine. It is the start of an allergic reaction. Common triggers are:

  • Foods like milk, fish or nuts
  • Drugs like aspirin or penicillin
  • Food additives like flavorings and preservatives
  • Bug bites
  • Extreme cold or heat
  • Pressure on the skin
  • Viral infections
  • Skin contact with allergens

Treatment for Angioedema

You can take antihistamines to ease your symptoms. If over-the-counter medicine does not help or your hives do not go away, see your doctor. They may prescribe steroid pills or prescription antihistamines.
