Urticaria (Hives, Welts, Nettle Rash)

When your skin reacts, we react faster.

With urticaria, itchy hives form on various parts of the body. Where there is also swelling of the face and hands, it is called angioedema. If the symptoms last longer than six weeks, the condition is considered chronic and together we should start to look for the causes.

Your questions. Our answers.

What causes the symptoms of urticaria?

The cause is often the release of the tissue hormone histamine from mast cells and basophils in an allergic reaction. However, certain drugs can also trigger the symptoms. Histamine widens smaller blood vessels, making them more permeable. This results in reddened skin and the formation of hives. Histamine is also involved in the development of itching.

What causes urticaria?

Infections, often in combination with medication (e.g. aspirin, antibiotics), allergic reactions and intolerances can be among the extremely varied causes of acute urticaria.

Which examinations are useful with urticaria?

In addition to a basic laboratory examination, we also exclude all allergies and take a skin sample, if necessary. A diet diary is helpful. This is followed by an examination where the patient is literally turned upside down in order to find the possible triggers. Finally, an exclusionary diet and provocation tests can help; a hospital stay is usually necessary for this.

How is urticaria treated?

In addition to creams for itching, possibly containing cortisone, we also use antihistamines. In therapy-resistant cases, we can use the anti-IgE antibody Omalizumab (Xolair) in treatment.
