Diagnosis To diagnose chronic hives, your health care provider will likely talk with you about your symptoms and look at your skin. One of the telling features of chronic hives is that the welts come and go at random. You might be asked to keep a diary to keep track of: • Your activities • Any medications, herbal remedies or supplements you take • What you eat and drink • Where hives appear and how long it takes a welt to fade and whether it leaves behind a bruise or other mark • Whether your hives come with painful swelling Treatment Treatment for chronic hives often starts with nonprescription anti-itch drugs (antihistamines). If these don't help, your health care provider might suggest that you try one or more of these treatments: Prescription anti-itch drugs. The usual treatment for chronic hives is prescription antihistamine pills that don't make you drowsy. These drugs ease itching, swelling and other allergy symptoms. Daily use of these drugs helps block the symptom-producing release of histamine. Examples include: • Cetirizine • Desloratadine (Clarinex) • Fexofenadine These medications have few side effects. If the nondrowsy antihistamines don't help you, your health care provider may increase the dose or add another type of antihistamine. Check with your health care provider before taking any of these medications if you're pregnant or breastfeeding, have a long-term medical condition, or take other medications. Other medications If the first-choice drugs don't eas...

Medications Treatments for hives and angioedema may include prescription drugs: • Anti-itch drugs. The standard treatment for hives and angioedema is antihistamines that don't make you drowsy. These medications reduce itching, swelling and other allergy symptoms. They're available in nonprescription and prescription formulations. • Drugs that suppress the immune system. If antihistamines are not effective, your doctor might prescribe a drug that can calm an overactive immune system. • Drugs for hereditary angioedema. If you have the type of angioedema that runs in families, you may take medication to relieve symptoms and keep the levels of certain proteins in your blood at levels that do not cause symptoms. • Anti-inflammatory drugs. For severe hives or angioedema, doctors may prescribe a short course of an oral corticosteroid drug — such as prednisone — to reduce swelling, inflammation and itching. Emergency situations For a severe attack of hives or angioedema, you may need a trip to the emergency room and an emergency injection of epinephrine — a type of adrenaline. If you have had a serious attack or your attacks recur despite treatment, your doctor may have you carry a penlike device that will allow you to self-inject epinephrine in emergencies. Clinical trials Lifestyle and home remedies If you're experiencing mild hives or angioedema, these tips may help relieve your symptoms: • Avoid triggers. These can include foods, medications, pollen, pet dander, latex and inse...

What are hives? Hives, or urticaria, are flat red welts that can appear anywhere on the skin and usually itch.
