There isn’t a universal list of “8 pills you should never take.” Many medicines can be used safely when appropriately prescribed. The risk depends on your kidney function, dose, duration, hydration, and other medicines.
Eight medications or medication groups that can cause kidney problems in certain circumstances include:
-
Ibuprofen — an NSAID painkiller; higher doses or prolonged use can reduce kidney blood flow and cause acute kidney injury. National Kidney Foundation+1
-
Naproxen — another NSAID with similar kidney risks. National Kidney Foundation
-
Diclofenac tablets/capsules — NSAID that can affect kidney function, particularly with long-term or high-dose use. National Kidney Foundation
-
Meloxicam — prescription NSAID; kidney risk increases in people with kidney disease and other risk factors. National Kidney Foundation
-
Ketorolac — a potent NSAID generally intended for short-term use; kidney toxicity is an important concern. National Kidney Foundation
-
Lithium — can cause kidney problems with prolonged use or excessive blood levels, so kidney function and lithium levels are monitored. National Kidney Foundation+1
-
Some proton-pump inhibitors (PPIs) such as omeprazole, pantoprazole and lansoprazole — long-term use has been associated with kidney-related problems; short-term use generally doesn’t carry the same concern. National Kidney Foundation
-
Certain antibiotics/antivirals/antifungals — some can directly affect the kidneys or accumulate when kidney function is reduced, requiring dose adjustment. National Kidney Foundation
Particularly important
If you already have kidney disease, are dehydrated, have heart failure, or take an ACE inhibitor/ARB or diuretic, NSAIDs such as ibuprofen and naproxen can be especially risky. The National Kidney Foundation recommends that people with CKD avoid self-treating with NSAIDs, particularly when eGFR is below 60. National Kidney Foundation
Don’t stop a prescribed medicine on your own, especially lithium, blood-pressure medicines, or other long-term treatments. A doctor or pharmacist can check your medications against your kidney function.
If you give me the names of the pills you currently take, I can tell you which ones have kidney-related concerns and which are generally kidney-safe.
