Treatment of Costochondritis in Patients with Chronic Kidney Disease

First-Line Treatment Approach

• The American College of Physicians recommends acetaminophen as the first-line analgesic for costochondritis in CKD patients, avoiding NSAIDs entirely due to nephrotoxicity risk, with physical therapy and reassurance as essential non-pharmacologic components 1, 2
• Acetaminophen should be initiated at conservative doses (maximum 2-3 grams daily with dose reduction in advanced CKD) as the primary analgesic, following the adapted WHO analgesic ladder for CKD patients 2

Critical Medication Avoidance

• The KDIGO guidelines explicitly state that NSAIDs should never be prescribed in CKD due to nephrotoxicity risk, posing significant risks including acute kidney injury, progressive GFR loss, electrolyte derangements, hypervolemia, and worsening of heart failure and hypertension 1

Monitoring and Follow-Up

• The American Heart Association recommends monitoring blood pressure in CKD patients as hypertension is common and stress from pain can exacerbate it 3, 4
