3. Proton Pump Inhibitors (PPIs)
Used for acid reflux and heartburn:
-
Omeprazole
-
Esomeprazole
Potential Risk
Long-term use has been linked in some studies to:
-
Acute interstitial nephritis
-
Increased risk of chronic kidney disease
If you’ve been taking these daily for years, it’s worth reviewing with your doctor whether continued use is necessary.
4. Certain Blood Pressure Medications (When Dehydrated)
ACE inhibitors and ARBs protect kidneys long-term — but in cases of severe dehydration or sudden illness, they can temporarily strain kidney function.
Examples:
-
Lisinopril
-
Losartan
These are often beneficial overall — but monitoring is key.
5. Diuretics (“Water Pills”)
Examples:
-
Furosemide
-
Hydrochlorothiazide
Why Caution Is Needed
They increase urine output. When combined with dehydration or NSAIDs, they can increase risk of kidney injury.
Hydration and monitoring electrolyte levels are important.
6. Lithium
Lithium is commonly prescribed for bipolar disorder.
Long-Term Risk
Extended use may cause chronic kidney changes in some individuals. Regular blood level monitoring is essential to reduce risk.
7. Some Antiviral Medications
Examples include:
-
Acyclovir
-
Tenofovir
High doses or dehydration can increase kidney strain. Doctors often adjust doses based on kidney function tests.
8. Contrast Dyes Used in Imaging
While not a “pill,” contrast agents used in CT scans can temporarily impact kidney function — especially in people with diabetes or existing kidney disease.
If you’re scheduled for imaging, your provider may check kidney labs beforehand.
