Medications to Avoid or Adjust If You Have Chronic Kidney Disease

When your kidneys don’t function the way they should, prescription and over-the-counter medications can build up in your blood and may cause additional damage to your kidneys or other parts of your body. That’s why it’s important for people with chronic kidney disease (CKD) to understand which medications make sense for them and which do not.

What medications to avoid with kidney disease

Here are some common over-the-counter and prescription medications that your doctor may tell you to avoid or adjust if you have kidney disease. We recommend that you talk to your doctor if you are taking any of these medications. Tell your doctor about all of your medications. Do not stop taking any medication without talking to your doctor first.

  • Pain medications also known as nonsteroidal anti-inflammatory drugs (NSAIDs)
    These medications reduce blood flow to the kidneys and should be avoided. NSAIDs can also be found in many medications marketed for fevers, colds, coughs, and sleeping problems. Always check the active ingredient labeling for NSAIDs to be sure.
  • Proton pump inhibitors (PPIs)
    These medications are used to treat acid reflux and heartburn, and some studies suggest that they can increase the risk for kidney disease, osteoporosis, or other nutritional deficiencies. If you’re on dialysis, you may have limitations on taking these medications. Always talk to your healthcare provider before taking PPIs or other acid reflux medications.
  • Cholesterol medications (statins)
    These medications are often prescribed to help lower cholesterol levels in the blood. Your doctor may need to adjust your dosage of these medications to protect your kidneys.
  • Antibiotic medications
    Antibiotics, antiviral, and antifungal medications may harm your kidneys, so your doctor will need to be aware of your level of kidney function before prescribing these treatments.
  • Diabetes medications
    Diabetes is the leading cause of kidney disease. It’s important that people living with diabetes control their blood sugar levels, which may involve the use of medication. If you have diabetes and are diagnosed with kidney disease, your doctor may need to adjust your medication dosage.
  • Antacids
    Over-the-counter medications for heartburn and upset stomach can interfere with your body’s electrolyte balance, which can be problematic for people with chronic kidney disease. Always check with your doctor before self-medicating. 
  • Herbal supplements and vitamins
    Many herbal supplements contain minerals such as potassium or phosphorus that can be damaging for people with kidney disease. In general, herbal and vitamin supplements may need to be avoided if you have kidney disease.
  • Contrast dye 
    Contrast dyes used in diagnostic tests such as MRIs, CT scans, or angiograms may increase your risk for kidney problems or acute kidney injury (AKI). If you're scheduled to have one of these tests, talk to the doctor ordering the test or your radiologist. Tell all health care professionals responsible for your care about your glomerular filtration rate (GFR) and CKD.

Talk to your doctor or pharmacist before taking over-the-counter medications and supplements

Chronic kidney disease can change the way your body processes certain substances, so it’s important that you talk to your doctor or pharmacist about all over-the-counter and prescription medications, as well as supplements or vitamins you take. When prescribed new medications, ask your doctor or pharmacist if the medication is safe to take with CKD, and tell them your current GFR. Open communication between you and your doctor can help ensure you’re protecting your kidney health.
