Which analgesic is generally preferred in CKD for mild pain, with NSAIDs avoided and dosing adjustments may be needed for some opioids?

• A. Acetaminophen
• B. Nonsteroidal Anti-Inflammatory Drugs
• C. Ibuprofen
• D. Morphine

Answer: (A)

Starting with the idea that kidney-friendly pain relief is the goal for CKD, acetaminophen is the best option for mild pain because it provides analgesia without affecting kidney function. NSAIDs harm kidney perfusion and can worsen CKD by reducing glomerular filtration, so they’re avoided. Acetaminophen avoids that nephrotoxic risk, making it the safer first-line choice for mild pain. Just be mindful of liver health and watch for liver toxicity with higher or chronic doses. If pain isn’t controlled with acetaminophen, opioids may be used, but many require dose adjustments because renal clearance of metabolites can lead to buildup and adverse effects. This makes acetaminophen the favored initial analgesic in CKD for mild pain.
