Summary
Bowel-preparation products can cause fluid loss and electrolyte shifts, and etidronate can also lower serum calcium and phosphate balance. Together they may add to electrolyte disturbance and strain renal function. Magnesium in the preparation may also bind oral etidronate.
What this interaction means in plain words
Etidronate 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
Additive electrolyte and volume disturbance, with possible chelation of etidronate by magnesium in the gut.
What to do
Hold etidronate on the day of bowel preparation and restart after the procedure once the patient is hydrated and eating. Check electrolytes and renal function in patients at risk.
