The best treatment is to identify the cause and rule it out to prevent recurrent attacks. For those who cannot find the cause or trigger at one time, symptomatic treatment can be used. For acute urticaria, antihistamines and calcium agents are commonly used to reduce vascular permeability. In addition to antihistamines, corticosteroids are also needed for severe lesions. Combined infections often require a combination of antihistamines, sebaceous steroids and antibiotics to completely control the condition. For chronic urticaria, antihistamines are the mainstay of treatment. Sometimes H1 and H2 receptor antagonists are used in combination. At present, the main antihistamines used are desloratadine and epalatine, cetirizine, etc. In addition to antihistamines, chronic urticaria is treated with immune-enhancing drugs, such as BCG polysaccharide nucleic acid injection, transfer factor and pavoline. At the same time, we also cooperate with Chinese herbal medicine to identify and type the treatment. After the symptoms are relieved, antihistamines should be gradually reduced according to the doctor’s prescription, and should not be stopped suddenly to avoid relapse. What should be noted in the life of chronic urticaria patients? 1, to pay attention to diet, to avoid triggers.
