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

The treatment methods for cold air-induced urticaria mainly include: 1. Avoiding triggers: Avoid exposure to cold air, keep warm, reduce outdoor activities, and minimize direct contact with cold air by wearing gloves, masks, and hats. 2. Medication: If symptoms do not improve, take antihistamine medications orally as directed by a physician, such as cetirizine or loratadine. These medications can effectively relieve itching and swelling caused by urticaria. Patients with severe symptoms or accompanied by anaphylactic shock or laryngeal edema should seek immediate medical attention. 3. Desensitization therapy: Under a doctor's guidance, gradually increase cold tolerance by repeated exposure to cold water. However, this method carries certain risks and should be chosen cautiously. 4. Traditional Chinese Medicine (TCM): For patients with chronic urticaria, treatment with TCM can be considered, such as using herbal foot baths with functions of warming the meridians and dispersing cold to help alleviate symptoms. 5. Daily care: Avoid scratching the affected areas, and keep bath water temperature moderate. Maintain regular exercise, follow a healthy diet, and enhance personal immunity.
