“Eight Pills You Shouldn’t Take Because They Damage Your Kidneys” — What’s Actually True?
That headline is too absolute. There isn’t a universal list of eight pills that everyone should avoid. Kidney risk depends on the medication, dose, duration, hydration, existing kidney function, and other medicines being taken.
Some important medication groups to be cautious about include:
Ibuprofen — an NSAID that can reduce blood flow to the kidneys and cause acute kidney injury, particularly at high doses, with prolonged use, or during dehydration.

Naproxen — another NSAID with similar kidney risks.

Diclofenac — an NSAID that can contribute to kidney injury, especially in people with kidney disease or other risk factors.

Indomethacin — another NSAID associated with acute kidney injury.

High-dose aspirin — doses above about 325 mg/day can have NSAID-like effects on the kidneys; low-dose aspirin prescribed for cardiovascular protection is a different situation.

Some antibiotics — certain antibiotics can directly affect the kidneys or accumulate when kidney function is reduced, although many remain perfectly appropriate when correctly dosed.

National Kidney Foundation
Some antiviral or antifungal medicines — some can cause kidney injury or require dose adjustment when kidney function is impaired.

Some diuretics (“water pills”) — these aren’t inherently kidney-damaging and are often beneficial, but excessive dosing can cause dehydration and contribute to acute kidney injury.

One important misconception
ACE inhibitors and ARBs are not simply “kidney-damaging drugs.” In fact, medicines such as lisinopril or losartan can protect kidney function and slow progression of chronic kidney disease in appropriate patients. They can, however, require monitoring and become more problematic in situations such as dehydration or when combined with NSAIDs and certain diuretics.

The biggest everyday warning
For people with kidney disease, NSAIDs are particularly important to discuss with a healthcare professional before using. The National Kidney Foundation recommends avoiding self-treatment with NSAIDs in CKD, especially when eGFR is below 60.

Don’t stop a prescribed medication simply because of a headline. If you give me the eight specific pills mentioned in the article, I can go through them one by one and label each as high risk, conditionally risky, generally safe, or misleadingly portrayed.
