The claim “Eight pills you shouldn’t take because they damage your kidneys” is an oversimplification. Some medications can affect kidney function, especially at high doses, with long-term use, or in people who already have kidney disease, but most are safe when used correctly and monitored appropriately.
Examples of medication groups that may require caution include:
- Nonsteroidal anti-inflammatory drugs (NSAIDs)
- Examples include ibuprofen and naproxen.
- They can reduce blood flow to the kidneys and may increase the risk of kidney injury, especially with dehydration, older age, or existing kidney problems.
- Certain antibiotics
- Some antibiotics can stress the kidneys or require dose adjustments in people with reduced kidney function.
- Some blood pressure medications
- Certain drugs affect kidney blood flow or potassium levels and may need monitoring through blood tests.
- Diuretics (“water pills”)
- They can alter fluid and electrolyte balance, which may affect kidney function if not managed properly.
- Some heart medications
- Certain medicines require kidney monitoring because they are cleared through the kidneys or affect kidney-related chemistry.
- Lithium
- Long-term use can affect kidney function in some people and requires regular monitoring.
- Certain chemotherapy or immune-suppressing medicines
- Some can be harmful to the kidneys and require careful dosing.
- High-dose supplements or unregulated products
- Some herbal products or supplements may contain substances that can harm kidneys or interact with medicines.
Important: Do not stop prescribed medications because of a headline. Many of these medicines provide major health benefits, and the risk depends on your health, dose, duration of use, and monitoring.
If you have kidney disease, diabetes, high blood pressure, are older, or take multiple medications, ask a doctor or pharmacist to review your medicines for kidney safety.
