Eight pills you shouldn’t take because they damage your kidneys

That kind of headline is usually exaggerated. There aren’t “eight specific pills everyone should avoid,” but it is true that certain medications can damage the kidneys if misused, overused, or taken without medical supervision—especially in high doses or in people with existing kidney problems.

Here are common medication groups that can affect kidney health:

1. Painkillers (NSAIDs)

Examples: Ibuprofen, Diclofenac, Naproxen

Can reduce blood flow to the kidneys
Risk increases with long-term or high-dose use
More dangerous if dehydrated or elderly

2. Some antibiotics

Examples: Gentamicin, Amikacin, Vancomycin

Used for serious infections
Can be toxic to kidney tissue if not closely monitored

3. Contrast dyes (used in scans)

Used in CT scans or angiography
Can temporarily stress kidneys, especially in at-risk patients

4. Diuretics (“water pills”)

Examples: Furosemide, Hydrochlorothiazide

Can cause dehydration or electrolyte imbalance if misused

5. Certain blood pressure medicines

Examples: ACE inhibitors (like Enalapril), ARBs (like Losartan)

Usually kidney-protective long-term, but can worsen kidney function in some conditions or dehydration

6. Proton pump inhibitors (acid reducers)

Examples: Omeprazole, Pantoprazole

Long-term heavy use has been linked in some studies to kidney inflammation (rare but possible)

7. Lithium (for mood disorders)

Requires regular blood monitoring
Can accumulate and damage kidneys over time

8. Herbal / “natural” remedies (often overlooked)

Some traditional or herbal products may contain hidden toxins or heavy metals
Examples vary widely and are unpredictable in quality

Important reality check

Most of these drugs are safe when used correctly and prescribed properly
Kidney damage risk usually comes from:
- long-term overuse
- dehydration
- self-medication
- ignoring dosage instructions
