Summary
Sulfate-based bowel preparations cause fluid loss and electrolyte shifts. With telmisartan, the risk of acute kidney injury and electrolyte problems increases, particularly with dehydration.
What this interaction means in plain words
Sodium sulfate / potassium sulfate / magnesium sulfate and Telmisartan 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
Preparation-induced volume depletion lowers renal perfusion, and angiotensin receptor blockade impairs compensatory glomerular filtration.
What to do
Maintain good hydration and consider holding telmisartan on the day of bowel preparation. Check creatinine and electrolytes in older patients or those with kidney disease.
What to ask your pharmacist
