Summary
NSAIDs can promote water retention and impair free water excretion, and large-volume bowel preparations cause fluid and electrolyte shifts. Together they may increase the risk of hyponatremia and renal injury.
What this interaction means in plain words
Naproxen and Sodium sulfate / potassium chloride / magnesium sulfate / polyethylene glycol 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
NSAID-related reduction of renal prostaglandins and enhanced ADH effect, together with preparation-induced fluid and electrolyte shifts.
What to do
Avoid naproxen during bowel preparation when possible and encourage balanced hydration. Check sodium and renal function if symptoms such as nausea, confusion or reduced urine output develop.
