Treatment for Kidney Infection focuses on eliminating the infection, relieving symptoms, and preventing complications. Doctors usually prescribe antibiotics based on the type of bacteria causing the infection, and it is important to complete the full course even if symptoms improve. Pain relievers and fever reducers may be given to manage discomfort. Drinking plenty of fluids helps flush bacteria from the urinary system. In severe cases, hospitalization, intravenous antibiotics, or further tests may be required to protect kidney function and prevent long-term damage.
