The claim “Eight pills that should not be taken because they affect the kidneys” is usually a simplified warning. Many medications can affect kidney function in certain people, but that does not mean everyone should avoid them. The risk often depends on your kidney health, dose, duration of use, age, hydration, and other medicines you take.
Common medication groups that may require kidney caution include:
- NSAID pain relievers
- Examples: ibuprofen and naproxen
- Can reduce blood flow to the kidneys, especially with long-term use, dehydration, or existing kidney disease.
- Certain antibiotics
- Some antibiotics can stress the kidneys or require dose adjustments when kidney function is reduced.
- Diuretics (“water pills”)
- Used for blood pressure or heart conditions; they can affect fluid and electrolyte balance.
- ACE inhibitors and ARBs
- Common blood pressure and heart medications. They can change kidney blood flow and potassium levels, so monitoring is often needed.
- Certain heart rhythm or heart medications
- Some require careful dosing based on kidney function.
- Some diabetes medications
- Kidney function is important when choosing and dosing certain diabetes medicines.
- Lithium
- A medication used for some mental health conditions; long-term use can affect kidney function and requires monitoring.
- High-dose supplements or certain herbal products
- Some supplements can contain ingredients that may harm kidneys or interact with medications
