Eight Pills That May Harm Your Kidneys (and What to Know)
The claim that certain pills “damage your kidneys” needs context. Many medications are safe and beneficial when used correctly, but some can affect kidney function—especially at high doses, with long-term use, during dehydration, or in people who already have kidney problems.
Never stop a prescribed medicine without speaking with a healthcare professional.
1. Nonsteroidal Anti-Inflammatory Drugs (NSAIDs)
Examples: ibuprofen, naproxen, and similar pain relievers
- Frequent or high-dose use can reduce blood flow to the kidneys and may contribute to kidney injury, especially in older adults or people with kidney disease, heart failure, or dehydration.
2. Certain Antibiotics
Some antibiotics can affect kidney function in susceptible people.
- Doctors may adjust doses or monitor kidney function depending on the medication and the patient’s health.
3. Proton Pump Inhibitors (PPIs)
Examples: medications used for acid reflux
- Long-term use has been associated in some studies with kidney problems, although the overall risk for an individual varies.
4. Certain Diuretics (“Water Pills”)
Used for blood pressure, heart failure, or fluid retention.
- They can affect kidney function if they cause dehydration or electrolyte changes, especially if not monitored.
5. Some Blood Pressure Medications (in Specific Situations)
Certain medicines that affect kidney blood flow can cause changes in kidney function, particularly after starting treatment, changing doses, or during illness.
- These medications can also be kidney-protective for many people, so they should only be adjusted by a clinician.
6. Some Antiviral Medications
Certain antiviral drugs can affect kidney function and may require dose adjustments or monitoring.
7. Some Chemotherapy and Immune-Suppressing Medications
Some specialized treatments can be toxic to the kidneys, which is why doctors often monitor kidney tests during treatment.
8. High-Dose or Unregulated Supplements
Some herbal products and high-dose supplements may contain substances that can stress or injure the kidneys
