Acute and chronic urticaria. Challenges and considerations for primary care physicians.
Urticaria and angioedema are common dermatologic problems seen by primary care physicians. A carefully taken history, physical examination, specific tests, and skin biopsy often provide useful diagnostic information. In patients with chronic urticaria, urticarial vasculitis and diseases that mimic urticaria need to be ruled out. A variety of treatment options are available for patients with urticaria and urticarial vasculitis. Pharmacologic therapy is useful when the specific cause is undetermined. When a trigger has been identified, the patient must avoid exposure to it. Patient education is an important component of management and should include instructions on crisis management, particularly for patients who have angioedema or a tendency for anaphylaxis.
