The claim “Eight pills you shouldn’t take because they damage your kidneys” is often shared online without enough context. Many medicines are safe and necessary when used correctly, but some can affect kidney function in certain people—especially at high doses, with long-term use, during dehydration, or when kidney disease is already present.
Medicines that may require kidney caution
- Nonsteroidal anti-inflammatory drugs (NSAIDs)
- Examples: Ibuprofen and Naproxen
- Frequent or high-dose use may reduce blood flow to the kidneys and increase the risk of kidney injury in some people.
- Certain antibiotics
- Some antibiotics can affect kidney function, especially if doses are not adjusted for kidney health or if a person is already at risk.
- Some blood pressure medicines
- Certain medicines that affect kidney blood flow or potassium levels may require monitoring with blood tests.
- Diuretics (“water pills”)
- These can change fluid and electrolyte levels, so doctors may monitor kidney function and minerals.
- Some acid-reducing medicines
- Long-term use of certain stomach-acid medications may be associated with kidney concerns in some people.
- Certain antiviral medicines
- Some antiviral treatments can affect the kidneys and are usually monitored by healthcare providers.
- Some chemotherapy medicines
- Certain cancer treatments can be hard on the kidneys, which is why kidney tests are often checked during treatment.
- High-dose supplements or herbal products
- Some supplements can contain substances that may stress the kidneys or interact with medicines.
