Certain medicines can harm the kidneys, especially when taken too often, at high doses, combined with other drugs, or in people who already have kidney disease, dehydration, diabetes, or high blood pressure. It’s important not to stop prescribed medicines without talking to a healthcare professional.
Here are eight types of pills that can damage kidneys in some situations:
- Nonsteroidal anti-inflammatory drugs (NSAIDs)
Examples: ibuprofen, naproxen, diclofenac- Can reduce blood flow to the kidneys and trigger acute kidney injury, especially with dehydration or long-term use.
- High-dose aspirin
- Regular low-dose aspirin used for certain heart conditions is different from high-dose pain-relief use, which can stress the kidneys.
- Certain antibiotics
Examples: gentamicin, tobramycin, vancomycin (and some others)- Some can cause kidney inflammation or injury, particularly at high doses or in vulnerable patients.
- Proton pump inhibitors (PPIs) for acid reflux
Examples: omeprazole, pantoprazole, esomeprazole- Long-term use has been associated with kidney inflammation in some people.
- Diuretics (“water pills”)
Examples: furosemide, hydrochlorothiazide- Can contribute to kidney problems if they cause excessive fluid loss or electrolyte changes.
- Certain blood pressure medicines (in specific situations)
Examples: ACE inhibitors and ARBs (such as lisinopril or losartan)- These medicines often protect kidneys in conditions like diabetes, but they can raise kidney risk during dehydration, severe illness, or certain drug combinations.
- Lithium (used for bipolar disorder)
- Long-term use can affect kidney function and requires regular monitoring.
- Some chemotherapy and immune-suppressing medicines
Examples: cisplatin, cyclosporine, tacrolimus- These can be toxic to kidney tissue and usually require blood tests.
Other kidney risks: herbal supplements, unregulated “detox” products, and taking multiple medicines that affect the kidneys at the same time.
Seek medical advice promptly if you notice much less urine, swelling in the legs/face, blood in urine, severe fatigue, confusion, or sudden nausea/vomiting after starting a medicine.
If you tell me your age, any kidney problems, and the names of the pills you take, I can help you check which ones may need caution.
