Abstract
Urticaria is a very frequent disease. The life time risk to experience at least one episode of urticaria is around 15 - 25 %. This article summarizes the most important definitions, classifications and diagnostic procedures in urticaria, as well as the evidence based management of urticaria. The recommendations given in this article are in accordance with two recent position papers by the European Academy of Allergology and Clinical Immunology (EAACI), the Global Allergy and Asthma European Network (GA2LEN), the European Dermatology Forum (EDF), and the World Allergy Organization (WAO).
