If you’re referring to the headline “Eight pills you shouldn’t take because they damage your kidneys,” it’s based on a real concern, but it can be misleading. Many medications are safe and beneficial when prescribed and monitored properly. The risk depends on the specific drug, dose, duration, hydration status, and a person’s kidney health.
Medication groups that may affect the kidneys in some people include:
- NSAID pain relievers
- Examples include ibuprofen and naproxen.
- Frequent or high-dose use may reduce kidney blood flow and increase the risk of kidney injury, especially in people with kidney disease, dehydration, or heart problems.
- Certain antibiotics
- Some antibiotics can affect kidney function and may require dose adjustments or monitoring.
- Some antiviral medications
- Certain antivirals are processed through the kidneys and may need careful dosing.
- Diuretics (“water pills”)
- These can contribute to dehydration or electrolyte changes if not properly monitored.
- Lithium
- A medication used for some mood disorders that can affect kidney function with long-term use, requiring regular blood tests.
- Some chemotherapy medicines
- Certain cancer treatments can be harmful to kidney tissue and require kidney monitoring.
- Some immune-suppressing medications
- Certain drugs used after transplants or for autoimmune conditions can affect kidney function.
- High-dose or unregulated supplements
- Some herbal products and concentrated supplements may contain substances that can stress the kidneys or interact with medications.
Important: Do not stop a prescribed medicine because of a list online. If you take regular medications, especially if you have diabetes, high blood pressure, heart disease, or known kidney problems, ask a healthcare professional to review your medicines and whether kidney tests are needed.
Signs that may need medical attention include swelling, major changes in urination, blood in urine, unusual fatigue, nausea, or sudden changes in blood pressure.
