At present, there is no medicine with the fastest effect for vasculitis, and the medicine should be chosen according to the patient’s condition. Vasculitis can be effectively controlled by taking glucocorticosteroids and immunosuppressants. 1. Glucocorticosteroids: the basic treatment of vasculitis is glucocorticosteroids, such as methylprednisolone, prednisone, etc. The dosage and usage of glucocorticosteroids depend on the location and severity of the lesion. During the use of glucocorticosteroids, there may be increased blood pressure, osteoporosis, electrolyte disorders and other adverse reactions, during the use of patients need to be closely examined blood glucose, blood pressure, electrolytes and other relevant indicators. 2. Immunosuppressant: Anyone with renal, pulmonary, neurological, cardiac and other important organ involvement should be treated with immunosuppressant as early as possible. Commonly used immunosuppressants include cyclophosphamide, azathioprine, methotrexate and so on. Bone marrow suppression, nausea, vomiting, liver and kidney function damage and other adverse reactions may occur during the use of immunosuppressants. Vasculitis treatment drugs need to be used under the guidance of a doctor, do not self-medication. It is recommended that patients go to the hospital in a timely manner and follow the doctor’s instructions to standardize the treatment.
