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

Cold air allergic urticaria, medically termed cold urticaria, is primarily treated through the following approaches: 1. Avoid cold exposure: Avoid direct exposure to cold air and reduce cold stimulation to the skin by taking warming measures such as wearing gloves, masks, and hats, thereby staying away from allergens and effectively relieving allergic symptoms. 2. Medication: Under medical guidance, antihistamines such as cetirizine or loratadine may be used to alleviate allergic symptoms. If symptoms are severe, corticosteroids such as dexamethasone or prednisone may also be prescribed by a physician. Additionally, topical medications such as diphenhydramine cream and calamine lotion can help relieve itching and other symptoms. 3. Desensitization therapy: Under a physician's supervision, desensitization therapy may be conducted to gradually acclimate the body to cold environments and reduce allergic reactions. However, this method carries certain risks and should be performed with caution. 4. Enhance immunity: Improving immunity through methods such as taurine injections and consistent physical exercise can help fundamentally improve allergic constitution and reduce the recurrence of urticaria.
