The claim “Eight pills you shouldn’t take because they damage your kidneys” is often used in health headlines, but the reality is more nuanced: many medications are safe when used correctly, while some can harm the kidneys in certain people, at high doses, or with long-term use.
Medications that commonly require kidney caution include:
- Nonsteroidal anti-inflammatory drugs (NSAIDs)
- Examples: ibuprofen, naproxen, diclofenac
- Long-term or high-dose use can reduce blood flow to the kidneys and increase the risk of kidney injury, especially in older adults or people with kidney disease.
- Certain antibiotics
- Some antibiotics can stress the kidneys, particularly in people with reduced kidney function or when doses are not adjusted properly.
- Some antiviral medications
- Certain antiviral drugs may require kidney monitoring and dose adjustments.
- Diuretics (“water pills”)
- These can affect fluid balance and kidney function, especially if dehydration occurs.
- Some blood pressure medicines
- Medicines that affect the kidney’s blood flow may require monitoring, particularly when starting treatment or changing doses.
- Proton pump inhibitors (PPIs)
- Examples: omeprazole, pantoprazole
- Long-term use has been associated in some studies with kidney problems, though the risk for an individual varies.
- Certain heart medications
- Some require careful monitoring of kidney function and electrolytes.
- High-dose supplements or herbal products
- Some supplements, especially those with unknown ingredients or contaminants, may harm kidneys.
Protect your kidneys by:
- Avoiding unnecessary painkiller use.
- Drinking enough fluids unless your doctor has restricted fluids.
- Telling healthcare providers about all medicines and supplements you take.
- Checking kidney function if you take medicines that can affect the kidneys.
Do not stop prescribed medication without medical advice. If you share the names of the pills you take, I can help identify whether they have known kidney risks.
