8 Common Medications That Can Harm Your Kidneys (and Why Self-Medicating Can Be Risky)
Your kidneys filter waste and many medications from your blood. While most medicines are safe when used as directed, some can damage the kidneys if taken in high doses, for long periods, or by people with existing kidney disease.
1. NSAID Pain Relievers
Examples:
- Ibuprofen
- Naproxen
- Diclofenac
These can reduce blood flow to the kidneys, especially in older adults, people with dehydration, heart failure, or chronic kidney disease.
2. Certain Antibiotics
Some antibiotics, particularly at high doses or in people with reduced kidney function, can affect the kidneys. Doses often need to be adjusted if kidney function is impaired.
3. Proton Pump Inhibitors (PPIs)
Examples:
- Omeprazole
- Pantoprazole
- Esomeprazole
Long-term use has been linked to a higher risk of certain kidney problems in some studies, though the overall risk is low for most people.
4. Diuretics (“Water Pills”)
Examples:
- Furosemide
- Hydrochlorothiazide
These can contribute to dehydration or electrolyte imbalances, which may affect kidney function if not monitored.
5. ACE Inhibitors and ARBs
Examples:
- Lisinopril
- Enalapril
- Losartan
