Angioedema
Angioedema is swelling that develops under the skin and in the tissues that line some organs. Painful swelling can develop on the face and in other parts of the body. Swelling in the belly may cause pain, nausea, vomiting, and diarrhea.
Angioedema may appear as a reaction to a substance (allergen). Allergens include medicines, foods, insect bites, animal dander, and pollen. Angioedema also may appear during changes in temperature or emotional stress, or after an infection or illness. It can also run in families.
Most cases of angioedema will go away within a few days without treatment. However, swelling in the throat can interfere with breathing and may be life-threatening. Angioedema also may be a sign of a more serious allergic reaction (anaphylaxis) that requires emergency care. Since angioedema can get worse quickly, a person with this condition should be evaluated by a doctor.
How can you care for yourself when you have angioedema?
- Take your medicines exactly as prescribed. Call your doctor if you think you are having a problem with your medicine. You will get more details on the specific medicines your doctor prescribes. Some medicines used to treat angioedema can make you too sleepy to drive safely. Do not drive if you take medicine that may make you sleepy.
- Avoid foods or medicine that may have triggered the swelling.
- For comfort:
- Try taking a cool bath. Or place a cool, wet towel on the swollen area.
- Avoid hot baths and showers.
- Wear loose clothing.
- Your doctor may prescribe a shot of epinephrine to carry with you in case you have a severe reaction. Learn how to give yourself the shot and keep it with you at all times. Make sure it has not expired.
