What are the treatment methods for cold-induced allergic urticaria?

The treatment of cold-induced allergic urticaria mainly includes the following aspects: 1. General management: Maintain a warm indoor environment and avoid direct exposure to cold air. When going outdoors, wear masks, hats, and thick, warm clothing to minimize skin irritation caused by cold air. 2. Medication: Antihistamines such as cetirizine and loratadine are the first-line treatments to relieve symptoms like itching and swelling. For severe cases, corticosteroids such as dexamethasone or prednisone may be prescribed by a physician to rapidly control inflammatory responses. Topical anti-itch medications such as diphenhydramine cream or calamine lotion can be used when itching is present. 3. Desensitization therapy: Under the guidance of a specialist, gradually increasing exposure to cold water may help improve the body's tolerance to cold. However, potential risks should be carefully considered. These treatment approaches should be tailored to individual patients and carried out under medical supervision. Additionally, patients should actively avoid triggering factors and strengthen daily self-care to promote recovery.
