What medications can damage your kidneys?

Medically reviewed by Sally Chao, MD. Last updated on March 15, 2022.

Official answer


Lots of medications can harm the kidneys and interfere with their function. Your kidneys filter blood and remove wastes and extra water to make urine.

This list of medications that may damage kidneys includes:

Pain relievers

Both over-the-counter and prescription nonsteroidal anti-inflammatory drugs (NSAIDs) can reduce blood flow to the kidneys, which is dangerous for people who already have decreased kidney function. In addition, long-term use of pain medicines such as acetaminophen, aspirin and NSAIDs can cause damage within the internal structures of the kidney (analgesic nephropathy).

Antibiotics and antivirals

Various classes of antibiotics have different effects on kidney function. Some may cause more damage than others. There are different antibacterial, antifungal and antiviral medicines that rely less on the kidneys to filter and are safer for your kidneys.


Laxatives called sodium phosphate (OSP) products that are used before a colonoscopy to clean out the colon can harm the kidneys. They can cause loss of kidney function or acute kidney injury and other issues linked to the deposit of phosphate crystals in the kidneys.

Cholesterol medications

Statins, a common medication taken to lower cholesterol, may worsen chronic kidney disease.

Antacid medications

Antacids that contain aluminum or magnesium can disrupt the body's electrolyte balance in people with chronic kidney disease.

Proton pump inhibitors (PPIs)

These drugs are used to treat heartburn, but may result in chronic kidney damage.

Diabetes medications

Diabetes and kidney disease can travel together, and some diabetes medications are cleared by the kidneys. Doses may need adjusting based on kidney function.

Blood pressure-lowering drugs

Angiotensin-converting enzyme (ACE) inhibitors and other drugs that treat high blood pressure may contribute to kidney damage when used over the long term.
