Whether chronic nephritis requires lifelong medication needs to be assessed according to the patient’s condition. If the patient’s condition is relatively mild, regular review can be conducted and lifelong medication is not required; if the patient’s renal function is impaired, lifelong medication is usually required to slow down the progressive deterioration of renal function. If the condition of chronic nephritis patients is relatively mild, such as only showing simple hematuria or proteinuria (<0.3g/d), they can be reviewed regularly and do not need lifelong medication. If patients with chronic nephritis have a large amount of urinary protein, hematuria, hypertension, edema and other manifestations, it usually indicates that there is a certain degree of renal function impairment, and it may be necessary to take long-term ACEI or ARB drugs, such as captopril, chlorosartan and other drugs to lower blood pressure, reduce urinary protein, and delay the progressive deterioration of renal function. Lifelong medication is required at this time. Patients with chronic nephritis are advised to visit regular hospitals in time and standardize treatment under the guidance of doctors.
