Answer
The best treatment for hives and associated swelling is to identify and remove the trigger, but this is not an easy task. Antihistamines are usually prescribed by your doctor or dermatologist to provide relief from symptoms. Antihistamines work best if taken on a regular schedule to prevent hives from forming in the first place. Chronic hives may be treated with antihistamines or a combination of medications. When antihistamines don't provide relief, oral corticosteroids may be prescribed. For severe hive or angioedema outbreaks, an injection of epinephrine (adrenaline) or a cortisone medication may be needed. How Can Hives Be Managed? While you're waiting for the hives and swelling to disappear, here are some tips: Avoid hot water; use lukewarm water instead. Use gentle, mild soap.
