What is the treatment for hives and/or angioedema?
Avoidance of the allergen is the best treatment. If it is caused by a medication, strict avoidance is necessary.
Allergists may recommend antihistamines to decrease histamine release, which can lessen the symptoms of hives and/or angioedema. They may be prescribed on a regular schedule to prevent symptoms. Chronic hives may be treated with antihistamines or a combination of medications. For severe hives and angioedema, an injection of epinephrine may be needed.
