“Eight pills you shouldn’t take because they damage your kidneys” — the reality
That headline is too absolute. Most medicines on such lists aren’t simply “bad for your kidneys.” The risk depends on the drug, dose, duration, kidney function, hydration, and what other medicines you’re taking. Some are also essential treatments that should never be stopped without medical advice.
Medicines that deserve particular caution include:
Ibuprofen — an NSAID that can reduce kidney blood flow and cause acute kidney injury, particularly with high doses, prolonged use, dehydration, or existing kidney disease.

Naproxen — another NSAID with similar kidney risks.

Diclofenac — an NSAID that can also affect kidney function, particularly with long-term or high-dose use.

Celecoxib — although different from older NSAIDs, it can still affect kidney blood flow and kidney function.

Meloxicam — another NSAID requiring caution, especially in people with chronic kidney disease.

Certain antibiotics — some can directly injure the kidneys, while others can accumulate when kidney function is reduced and therefore require dose adjustment.

Lithium — an effective medicine for bipolar disorder that can affect kidney function, particularly with long-term use, so kidney monitoring is important.

High-dose aspirin — aspirin above about 325 mg/day behaves more like an NSAID and can increase kidney risk. Low-dose aspirin prescribed for cardiovascular protection is a different situation and should not be stopped without medical advice.

One particularly important combination
The risk of acute kidney injury can rise when an NSAID is combined with an ACE inhibitor or ARB and a diuretic, especially when you’re dehydrated. This combination is sometimes called the “triple whammy.”

Don’t stop prescription medicines simply because you’ve seen a “kidney-damaging drugs” list online. Some medicines that can affect kidney function are also valuable for protecting the heart, controlling blood pressure, or treating serious illnesses.
If you tell me the names of the medicines you currently take, I can explain which ones require kidney-related precautions and which generally don’t.
