The claim that there are “eight pills you should never take” is too broad. Many medications can be safe and beneficial when used correctly, but some can increase the risk of kidney injury, especially in people with kidney disease, dehydration, older age, or when combined with other medicines.
Examples of medication groups that may affect kidney function include:
- Nonsteroidal anti-inflammatory drugs (NSAIDs)
- Examples include ibuprofen and naproxen.
- Frequent or high-dose use can reduce blood flow to the kidneys and may cause injury in some people.
- Certain antibiotics
- Some antibiotics can affect the kidneys, particularly in people with existing kidney problems or when used at high doses.
- Some blood pressure medicines
- ACE inhibitors and ARBs can change kidney function and potassium levels. They are often kidney-protective in certain conditions, but require monitoring.
- Diuretics (“water pills”)
- These can contribute to dehydration or electrolyte changes if not properly managed.
- Certain acid-reducing medicines
- Some proton pump inhibitors have been associated with kidney problems in rare cases.
- Some antiviral medications
- Certain drugs used to treat viral infections may require kidney monitoring.
- Some chemotherapy medicines
- Several cancer treatments can affect kidney function and require careful dosing and monitoring.
- Lithium
- A medication used for some mood disorders that can affect kidney function with long-term use and requires regular blood tests.
Protecting your kidneys
- Avoid taking painkillers or supplements frequently without medical advice.
- Stay hydrated, especially during illness or hot weather.
- Tell your healthcare professional about all medicines and supplements you take.
- Get kidney function tests if you use medicines that require monitoring.
Do not stop prescribed medications on your own. Many of these medicines are important and may be the best treatment when used appropriately.
If you list the medications you take (including over-the-counter pain relievers and supplements), I can help you understand which ones may need kidney monitoring.
