Mild symptoms of angioedema tend not to need treatment, as they often clear up on their own. Moderate or more severe symptoms -- such as if hives last more than a few weeks -- may require medicinal aid. If you do require medication, your doctor will probably prescribe antihistamines and anti-inflammatory medication. Home remedies can also be helpful in relieving some of the symptoms. Placing a cool compress on the swelling can help bring it down.
