How is a kidney infection treated?
- Antibiotics treat your bacterial infection.
- Acetaminophen decreases pain and fever. It is available without a doctor's order. Ask how much to take and how often to take it. Follow directions. Read the labels of all other medicines you are using to see if they also contain acetaminophen, or ask your doctor or pharmacist. Acetaminophen can cause liver damage if not taken correctly.
- NSAIDs , such as ibuprofen, help decrease swelling, pain, and fever. This medicine is available with or without a doctor's order. NSAIDs can cause stomach bleeding or kidney problems in certain people. If you take blood thinner medicine, always ask if NSAIDs are safe for you. Always read the medicine label and follow directions. Do not give these medicines to children younger than 6 months without direction from a healthcare provider.
- Prescription pain medicine may be given. Ask how to take this medicine safely.
- Surgery may be needed if a ureter is blocked. The ureter is the tube that takes urine from a kidney to the bladder. A blocked ureter can cause repeated kidney infections.
