Summary
Sulfate-based bowel preparations cause fluid loss and electrolyte changes that can reduce renal perfusion. NSAIDs such as naproxen further compromise renal blood flow, which raises the risk of acute kidney injury and the consequences of electrolyte disturbance.
What this interaction means in plain words
Naproxen and Sodium sulfate / ?magnesium sulfate / potassium chloride can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken.
Why it happens
Volume depletion and electrolyte shifts from the preparation add to NSAID inhibition of renal prostaglandins.
What to do
Avoid naproxen on the day of bowel preparation when possible and ensure adequate hydration. Check serum electrolytes and creatinine in patients with kidney disease, older adults or those on diuretics or RAAS inhibitors.
What to ask your pharmacist
