Chronic urticaria is basically treated symptomatically. Commonly used drugs are dexamethasone cream, fluoro easy ointment and so on. 1. Antihistamines: The first-line drugs for the treatment of urticaria are mainly antihistamines, such as loratadine and cetirizine. The occurrence of urticaria is mainly due to the release of histamine from mast cells in the body, so that the permeability of blood vessels increased, antihistamines can effectively inhibit the above situation. 2. The second line of medication can use hormonal drugs such as prednisone, immunosuppressants such as cyclosporine and so on. If the itching caused by chronic urticaria is severe, topical ointments such as compound dexamethasone cream, florazepam ointment and dieldrin cream can be added to bring about symptomatic relief. The vast majority of chronic urticaria usually goes into remission on its own within 2-5 years. If the patient develops chronic urticaria symptoms, or if the symptoms persist and do not improve, the patient should go to the hospital for treatment.
