8 Pills You Shouldn’t Take Carelessly Because They Can Harm Your Kidneys
Some medicines can affect kidney function, especially when taken at high doses, for long periods, during dehydration, or in people who already have kidney disease. That doesn’t mean you should stop prescribed medication on your own.
1. Ibuprofen and other NSAIDs
Common pain relievers such as ibuprofen can reduce blood flow through the kidneys and, in some circumstances, cause acute kidney injury. Risk is higher with dehydration, older age, kidney disease, or certain other medicines.
2. Naproxen
Naproxen is another NSAID. Like ibuprofen, prolonged or excessive use can increase the risk of kidney problems.
3. Diclofenac
Diclofenac is also an NSAID and can affect kidney function, particularly with long-term use or in people who have other risk factors.
4. High-dose aspirin
Low-dose aspirin prescribed for cardiovascular protection is different from taking high doses for pain. Higher doses can place additional stress on the kidneys, particularly in vulnerable people.
5. Some antibiotics
Certain antibiotics can affect the kidneys. The risk depends on the specific drug, dose, duration, and the person’s kidney function. Antibiotics should only be taken when appropriately prescribed.
6. Some antiviral medicines
Certain antivirals can cause kidney problems or require dose adjustments when kidney function is reduced. Your doctor or pharmacist may need to check your kidney function during treatment.
7. Some medicines for acid reflux
Certain proton-pump inhibitors, such as omeprazole and similar medicines, have been associated with kidney problems in some people, particularly with prolonged use. They are not automatically harmful and may be appropriate when medically indicated.
8. Herbal or dietary supplements
Some supplements can contain ingredients that are harmful to the kidneys or may interact with medications. “Natural” does not necessarily mean kidney-safe.
Protect Your Kidneys
Avoid taking more than the recommended dose, stay adequately hydrated unless you’ve been told to restrict fluids, and tell your healthcare professional about all medicines and supplements you take.
Most importantly, don’t stop a prescribed medicine simply because you’ve read that it can affect the kidneys. Your doctor may have prescribed it because its benefits outweigh its risks and may monitor your kidney function with blood or urine tests.
If you develop much less urine, blood in your urine, new swelling, severe weakness, persistent nausea/vomiting, or sudden confusion while taking medication, seek medical attention promptly.
