Urticaria is divided into acute urticaria and chronic urticaria. Acute urticaria can be cured, while chronic urticaria is difficult to get a cure. Acute urticaria can be treated with levocetirizine, vitamin C and calcium gluconate tablets for mild symptoms, while those with severe symptoms need to be treated with anti-allergy medication through intravenous input. Chronic urticaria is mainly affected by genetic factors, allergens and other factors, so it is difficult to achieve a cure. The majority of chronic urticaria can be effectively relieved after regular treatment. Patients with chronic urticaria are advised to exercise more and enhance their resistance to prevent chronic urticaria.
