Chronic nephritis can be treated with medications. Chronic nephritis is dominated by hematuria and proteinuria. If the symptoms are mild, symptomatic treatment can be given, such as the use of hematuriaan capsules, Huangkui capsules and treatment with Elaipril and Benadryl, thus preserving kidney, reducing urine protein and controlling blood pressure. If the symptoms are more severe, it is necessary to improve the relevant examination under the guidance of professional doctors, and if necessary, kidney biopsy can be performed to clarify the pathological type, find out the cause and guide the treatment. The current medications used include Kunming Shanhai Tong, Leigongdong Polyglucoside Tablets and prednisone, Tacrolimus and other medications to reduce urine protein and delay the failure of kidney function. Chronic nephritis must be checked regularly to observe the effect of treatment and complications.
