Eight pills you shouldn’t take because they damage your kidneys

If you’re referring to the headline “Eight pills you shouldn’t take because they damage your kidneys,” there’s an important distinction: there aren’t eight pills that everyone should avoid. Kidney risk depends on the drug, dose, duration, existing kidney function, dehydration, and other medicines.

8 medication groups that deserve particular caution

1. Ibuprofen — an NSAID that can reduce blood flow to the kidneys, especially with high doses or prolonged use.
2. Naproxen — another NSAID with similar kidney risks.
3. Diclofenac — can affect kidney function, particularly with prolonged use or in people already at risk.
4. Celecoxib — a COX-2 inhibitor that can also affect kidney blood flow.
5. Meloxicam — another NSAID that requires caution in people with kidney disease.
6. Certain antibiotics — some antibiotics can cause acute kidney injury or require dose adjustment when kidney function is reduced.
7. Lithium — long-term use can affect kidney function and requires regular monitoring.
8. Some proton-pump inhibitors (PPIs) such as omeprazole or lansoprazole — these aren’t automatically “bad for the kidneys,” but prolonged use has been associated with certain kidney problems and should be medically monitored when long-term treatment is needed. National Kidney Foundation+2

⚠️ Don’t stop prescribed medication on your own

This is especially important for medicines such as lithium, blood-pressure medications, antibiotics, or PPIs. A medication that can affect the kidneys may still be the right treatment when appropriately prescribed and monitored.

The biggest everyday concern is NSAID painkillers. The National Kidney Foundation specifically warns that high doses and long-term use of drugs such as ibuprofen, naproxen and diclofenac can harm the kidneys, with risk increasing in people who already have reduced kidney function.
