8 Medicines That Can Harm the Kidneys — What You Should Actually Know
The headline “eight pills you shouldn’t take” is misleading. Some medicines can injure the kidneys or accumulate when kidney function is reduced, but many are safe and necessary when prescribed at the right dose. Don’t stop a prescription on your own.
1. Ibuprofen
A common NSAID that can reduce blood flow to the kidneys, particularly with high doses, prolonged use, dehydration, or existing kidney disease.
2. Naproxen
Another NSAID with similar kidney risks. People with chronic kidney disease are generally advised to avoid self-treating with NSAIDs.
3. Diclofenac
This NSAID can also affect kidney function, particularly with prolonged or high-dose use.
4. Certain antibiotics
Some antibiotics can directly affect the kidneys, while others simply need a lower dose when kidney function is reduced. That doesn’t mean antibiotics should be avoided when they’re medically necessary.
5. Some antiviral medicines
Several antivirals are cleared through the kidneys and may require dose adjustments; some can cause kidney problems under particular circumstances.
6. Some antifungal medicines
Certain antifungal drugs can affect kidney function, and dosing may need to be adjusted according to kidney function.
