Treatment strategies in urticaria.

Urticaria is a common group of disorders encountered in dermatology and in a variety of other fields. In particular, acute urticaria and angiooedema are common medical emergencies, which are treated in the first instance in the Accident and Emergency Department, whereas chronic urticaria poses a challenge in the long-term treatment. This review presents the latest evidence about the treatment for urticaria and is based on the most recent international guidelines (GA(2)LEN, Global Allergy and Asthma Network, 2009). Patients with acute and chronic urticaria are often not treated appropriately and this review provides a guide for any clinician to treat the underlying cause as well as the symptoms of this disorder according to the latest evidence. Many new therapies are available to patients with urticaria refractory to common therapies and it is important to consider second- and third-line therapies.
