The claim “Eight pills you shouldn’t take because they damage your kidneys” is a common health-warning headline, but it needs context: many medicines can be safe when used correctly, while some can increase the risk of kidney injury in certain people, especially at high doses, with dehydration, or with existing kidney problems.
Medicines that are commonly associated with kidney risks include:
- Nonsteroidal anti-inflammatory drugs (NSAIDs)
- Examples: Ibuprofen, Naproxen
- Long-term use or high doses may reduce kidney blood flow and can contribute to kidney injury in some people.
- Certain antibiotics
- Some antibiotics can affect kidney function, especially in people with kidney disease or when combined with other risk factors.
- Certain blood pressure medicines (especially when combined with other drugs)
- Some medicines that affect the kidney’s blood flow may require kidney function and potassium monitoring.
- Diuretics (“water pills”)
- These can affect fluid balance and electrolytes, which may stress the kidneys if not monitored.
- Some heart medications
- Certain drugs require monitoring because changes in kidney function can affect safety.
- Lithium
- Long-term use can affect kidney function and requires regular blood tests.
- Some antiviral medicines
- Certain antivirals can affect the kidneys, depending on the drug and dose.
- High-dose or unnecessary supplements
- Some supplements, especially in excessive amounts or from unreliable sources, may pose kidney risks.
People who should be extra cautious
- Those with chronic kidney disease
- Older adults
- People who are dehydrated (vomiting, diarrhea, heavy sweating)
- People taking multiple medications
- People with diabetes or heart disease
Do not stop prescribed medicines without talking to a healthcare professional. The safest approach is to review your medication list with a doctor or pharmacist.
If you tell me the names of the pills you take, your age, and whether you have any kidney problems, I can help identify which ones may need caution.
