Frequently Asked Questions
Can ibuprofen damage my kidneys?
Yes. Ibuprofen and other NSAIDs reduce blood flow to the kidneys and can cause acute kidney injury, especially in people with existing kidney disease. Acetaminophen (Tylenol) is a safer alternative for pain.
What medications should I avoid with kidney disease?
NSAIDs (ibuprofen, naproxen), certain antibiotics (gentamicin), potassium supplements, aluminum-containing antacids, and high-dose vitamin C. Always check with your doctor or pharmacist before starting any new medication.
Are supplements safe for CKD?
Many supplements can be harmful with CKD. Potassium supplements can be dangerous, high-dose vitamin C increases kidney stone risk, and herbal supplements are often untested for kidney safety. Only take supplements approved by your doctor.
