Patients with nephritis can take amoxicillin. Nephritis usually refers to chronic glomerulonephritis, which is a sterile inflammation of the kidney, but treating this inflammation with antibiotics is ineffective because antibiotics only target bacterial inflammation, such as urinary tract infections. If a patient with nephritis has a combination of other infections, such as a urinary tract infection or a lung infection, antibiotics can be used to treat the condition. When choosing antibiotics, use antibiotics that have less effect on the kidneys, such as penicillin antibiotics and cephalosporin antibiotics, and amoxicillin is an antibiotic belonging to the penicillin class. If the patient is not allergic to penicillin, he or she can apply amoxicillin. In addition to amoxicillin, patients with nephritis can also try cephalosporin antibiotics, such as ceftriaxone, cefotaxime, etc.
