Cold urticaria (cold urticaria) can be treated by a variety of methods such as glycerite lotion, vitamins, glucocorticoids, cold desensitization and so on. 1. Glycolite lotion: Glycolite lotion is a topical drug that can temporarily relieve the patient’s symptoms. 2. Vitamins: Vitamins can reduce the patient’s capillary permeability, thus helping to improve the allergic reaction, such as vitamin C. 3. Glucocorticoid: it can effectively treat the systemic allergic reaction caused by cold urticaria, promote the edema to subside, and relieve the complications. 4. Cold desensitization: Cold desensitization can be performed by repeatedly exposing the patient to cold baths, but this method carries the risk of triggering systemic symptoms and should be performed under medical supervision. If cold urticaria is diagnosed, it is recommended that targeted treatment be carried out as soon as possible to avoid delaying the condition and causing serious consequences.
