Allergic vasculitis may be cured in mild cases, but it is more difficult to cure in severe cases. The treatment methods include general treatment, medication and so on, which are commonly as follows: 1. General treatment: pay attention to rest, light diet, appropriate exercise. 2. Drug treatment: most patients can take glucocorticosteroids, such as prednisone; when the condition is mild, antihistamines can be taken, such as chlorpheniramine maleate tablets, etc.; when the condition is severe, immunosuppressants can be applied jointly, such as cyclophosphamide. In addition, it is necessary to search for the cause of the disease. If the disease is caused by chemical allergy, it is necessary to avoid contacting the sensitizing chemicals. If it is caused by infection, anti-infection treatment should be carried out, such as the use of cefadroxil, cefixime, etc., to remove the infected lesions. Allergic vasculitis should be treated promptly to avoid delays and serious consequences.
