Summary
Osmotic bowel preparations cause fluid loss and electrolyte shifts. With an ARB and a thiazide, this raises the risk of dehydration, acute kidney injury, and electrolyte-related arrhythmias or seizures.
What this interaction means in plain words
Candesartan-hydrochlorothiazide 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 volume depletion and electrolyte shifts combine with diuretic and ARB effects on renal perfusion and electrolytes.
What to do
Ensure good hydration, consider holding the diuretic and ARB on the day of preparation, and check electrolytes and creatinine in higher-risk patients.
