Summary
Osmotic bowel preparations can cause fluid loss and shifts in potassium, magnesium and sodium. These disturbances in a patient taking dronedarone, which prolongs the QT interval, may precipitate serious arrhythmias.
What this interaction means in plain words
Dronedarone 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
Bowel-prep-induced electrolyte and fluid disturbances add to dronedarone's QT-prolonging effect.
What to do
Ensure adequate hydration, check electrolytes before the preparation when risk is high, and consider an ECG in patients with other arrhythmia risk factors.
