If you mean medicines that can harm the kidneys, it’s not accurate to say that eight specific pills are always dangerous. Risk depends on the drug, dose, duration, dehydration, and existing kidney function.
Some important examples are:
Ibuprofen — Advil, Motrin
Naproxen — Aleve, Naprosyn
Diclofenac tablets/capsules — Voltaren and others
Indomethacin — Indocin
Meloxicam — Mobic
Celecoxib — Celebrex
High-dose aspirin — particularly doses above 325 mg/day
Lithium — long-term use can affect kidney function
The first seven are NSAIDs or related anti-inflammatory medicines. They can reduce blood flow to the kidneys and potentially cause acute kidney injury or worsen chronic kidney disease, particularly at high doses or with prolonged use.

Important: Don’t stop a prescribed medicine such as lithium without talking to your doctor. And don’t assume every painkiller damages the kidneys—acetaminophen (paracetamol) is generally considered kidney-safe at recommended doses.

If you tell me which pills you currently take, I can explain which ones are kidney-risky and which are generally safe.
