Summary
Large-volume bowel preparations can cause fluid shifts and hyponatremia, and NSAIDs promote water retention and reduce renal perfusion. Together they raise the risk of electrolyte imbalance and kidney injury.
What this interaction means in plain words
Diflunisal 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 effects on renal prostaglandins and water handling add to fluid and electrolyte disturbances caused by the preparation.
What to do
Withhold diflunisal during bowel preparation when practical and encourage appropriate fluid intake. Check sodium and renal function if symptoms or risk factors are present.
