Summary
Bowel preparations cause fluid loss and electrolyte shifts, and NSAIDs reduce renal prostaglandin-mediated perfusion. Together they may raise the risk of acute kidney injury in volume-depleted patients.
What this interaction means in plain words
Naproxen and Sodium picosulfate / magnesium oxide / anhydrous citric acid 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
Bowel-prep-induced volume depletion and electrolyte disturbance combined with NSAID-mediated renal vasoconstriction.
What to do
Hold naproxen around the bowel preparation where practical, particularly in older patients or those with renal impairment, and keep the patient well hydrated. Check renal function and electrolytes if risk factors are present.
