The headline “Eight pills you shouldn’t take because they damage your kidneys” is an oversimplification. It is true that some medications can affect kidney function in certain people, especially at high doses, with long-term use, during dehydration, or in people who already have kidney disease. But many of these medicines are safe and beneficial when used correctly and monitored by a healthcare professional.
Examples of medications that may require kidney caution include:
- Nonsteroidal anti-inflammatory drugs (NSAIDs)
- Examples: ibuprofen, naproxen
- Can reduce blood flow to the kidneys and may cause kidney injury, especially with frequent use or in people at risk.
- Certain antibiotics
- Some antibiotics can affect kidney function, particularly in vulnerable patients or at high doses.
- Some blood pressure medications
- ACE inhibitors and ARBs can change kidney blood tests and require monitoring, though they are often kidney-protective in many conditions.
- Diuretics (“water pills”)
- Can affect fluid and electrolyte balance, which may stress the kidneys if not managed properly.
- Lithium (a mood stabilizer)
- Long-term use can affect kidney function in some people and requires monitoring.
- Certain contrast dyes used in imaging tests
- These are not everyday pills, but they can pose risks for some people with kidney problems.
- High-dose or unnecessary supplements
- Some herbal products and excessive doses of certain vitamins or minerals can harm the kidneys.
- Some cancer or immune-system medications
- Certain treatments require kidney monitoring because they can be toxic to the kidneys.
Important: Do not stop prescribed medication because of a scary headline. If you are concerned, a doctor or pharmacist can review your medicines, kidney function, and risk factors.
People at higher risk of medication-related kidney problems include those with chronic kidney disease, diabetes, older age, dehydration, or use of multiple medications. Regular kidney blood tests can help detect problems early.
