Eight Types of Pills That Can Harm Your Kidneys (Especially When Misused)
The headline “Eight pills you shouldn’t take because they damage your kidneys” is a bit misleading. Many medications can affect the kidneys, but that does not mean everyone should avoid them. In many cases, these medicines are important and safe when taken at the correct dose with proper monitoring.
Here are common medication categories that may pose kidney risks for some people:
1. NSAID pain relievers
Examples:
- Ibuprofen
- Naproxen
- Diclofenac
These can reduce blood flow to the kidneys and may increase the risk of kidney injury, especially with frequent use, high doses, dehydration, or existing kidney disease.
2. Certain antibiotics
Some antibiotics can affect kidney function in susceptible people.
Doctors may adjust doses or monitor kidney function, especially in older adults or people with kidney problems.
3. Some antiviral medications
Certain antiviral drugs can put stress on the kidneys and may require dose adjustments.
4. Some blood pressure medications
Medicines such as ACE inhibitors and ARBs can change kidney blood tests, but they are also commonly used to protect kidney function in many people with conditions like diabetes or high blood pressure.
Monitoring is often the key.
5. Diuretics (“water pills”)
Used for high blood pressure, heart failure, and fluid retention.
They can affect:
- Fluid balance
- Electrolytes
- Kidney function
6. Proton pump inhibitors (PPIs)
Used for acid reflux and stomach acid problems.
Long-term use has been associated in some studies with kidney problems in certain people, though these medicines are helpful when appropriately prescribed.
7. Certain chemotherapy medicines
Some cancer treatments can be harmful to the kidneys, which is why patients are monitored closely during treatment.
8. Some supplements and herbal products
Not all supplements are harmless. Certain products may contain substances that can stress the kidneys or interact with medications.
Protecting your kidneys
- Avoid taking higher doses than recommended.
- Tell your healthcare provider about all medicines and supplements you use.
- Stay hydrated, especially when sick or in hot weather.
- Have kidney function checked if you take long-term medications or have risk factors.
Important: Do not stop prescribed medication because of a list like this. The safest approach is to review your medicines with a doctor or pharmacist, who can weigh the benefits and risks for your specific situation.
