The claim “eight pills you shouldn’t take because they damage your kidneys” is often shared online without context. Many medicines are safe when used correctly, but some can increase the risk of kidney problems, especially at high doses, for long periods, or in people with existing kidney disease.
Examples of medicines that may affect the kidneys include:
- NSAID pain relievers
- Examples: ibuprofen, naproxen, diclofenac
- Frequent or high-dose use can reduce blood flow to the kidneys.
- Certain antibiotics
- Some antibiotics can stress the kidneys and may require dose adjustments.
- Some antiviral medications
- Certain antiviral drugs can affect kidney function and need monitoring.
- Lithium
- A medication used for some mental health conditions; long-term use may affect the kidneys in some people.
- Some diuretics (“water pills”)
- Can alter fluid and electrolyte balance.
- Certain chemotherapy medicines
- Some cancer treatments can be kidney-toxic and require monitoring.
- Some acid-reducing medicines (when used long-term)
- Certain proton pump inhibitors have been associated with kidney problems in some studies.
- Unregulated supplements or herbal products
- Some may contain substances that can harm the kidneys.
Important: Do not stop prescribed medicines on your own. The risk depends on the exact medication, your dose, hydration, age, and kidney health.
If you list the names of the pills you take, I can help check whether any have known kidney concerns.
