Urticaria can be treated with injections. Intravenous medications include compound glycyrrhizic acid monoammonium S chloride injection 200mL once a day or compound glycyrrhizin injection 0.12g once a day. Glucocorticoids can also be applied, but because this drug has certain side effects, it needs to be calculated strictly according to the weight as well as the degree of the disease, and needs to be judged in an interview. In addition, intramuscular injection of chlorpheniramine maleate injection or glucocorticosteroid compound betamethasone injection can be used once a day for temporary treatment. When applying glucocorticoid injection, the patient needs to be tested for intrapulmonary infection or tuberculosis. If so, it should not be applied, because the application of hormones may cause the spread and aggravation of the infection.
