Treatment of urticaria

Abstract

Urticaria and angioedema can be caused by allergic and non-allergic mechanisms. While acute urticaria usually resolves quickly, chronic urticaria can persist for years. Management begins with a classification of the type of urticaria. Extensive investigations are usually unnecessary. Treatment includes avoiding the factors which provoke the reaction. When this is not possible, antihistamines remain the treatment of choice. A non-sedating antihistamine is preferred. More severe cases may require corticosteroids or immunosuppressant drugs.
