Eight Types of Pills That Can Harm Your Kidneys (Especially When Misused)
The kidneys filter many substances from your blood, and some medications can affect kidney function, particularly when taken in high doses, for long periods, or by people with existing kidney problems. This does not mean everyone taking these medicines will develop kidney damage—many are safe when used correctly and monitored when needed.
1. Nonsteroidal anti-inflammatory drugs (NSAIDs)
Examples include ibuprofen and naproxen.
- Frequent or high-dose use can reduce blood flow to the kidneys and may increase the risk of kidney injury, especially in people who are dehydrated or have kidney disease.
2. Certain antibiotics
Some antibiotics can affect the kidneys in certain situations, particularly at higher doses or in people with reduced kidney function. Doctors may adjust doses based on kidney health.
3. Some acid-reducing medications
Certain long-term uses of acid-suppressing medicines have been associated with kidney problems in some studies, though the overall risk varies by person.
4. Some blood pressure medicines
Certain medications that affect the renin-angiotensin system can change kidney function and potassium levels, so doctors often monitor blood tests when starting or adjusting them.
5. Some diuretics (“water pills”)
These can affect fluid balance and electrolytes, especially if someone becomes dehydrated.
6. Certain antiviral medications
Some antivirals can stress the kidneys and may require dose adjustments or monitoring.
7. Some chemotherapy medicines
Certain cancer treatments can be harmful to the kidneys and are usually given with careful monitoring.
8. Unregulated supplements or “natural” pills
Some herbal products and supplements may contain substances that can harm the kidneys or interact with medicines.
Protect your kidney health:
- Avoid taking more than the recommended dose of painkillers.
- Stay hydrated, especially during illness or hot weather.
- Tell your healthcare provider about all medicines and supplements you use.
- Get kidney function checked if you have risk factors such as diabetes, high blood pressure, or a history of kidney disease.
