Urticaria: Diagnosis and Management

Abstract

Urticaria is a common dermatologic condition that affects about 20% of the population. It is caused by the release of histamines in response to a trigger. It is subdivided into acute urticaria and chronic urticaria (urticaria lasting more than 6 weeks). First-line treatment is second-generation H1-antihistamines and avoidance of known triggers. Long-term prevention also focuses on minimizing exposure to triggers including hot water, nonsteroidal anti-inflammatory drugs, tight clothing, and known allergens.
