Summary
Bowel preparations can cause fluid loss and electrolyte disturbances including low potassium, and isoproterenol further shifts potassium into cells. Hypokalemia could increase the risk of arrhythmias, particularly given isoproterenol's chronotropic effects.
What this interaction means in plain words
Isoproterenol 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
Additive hypokalemia from beta-2-mediated cellular uptake and gastrointestinal losses.
What to do
Check electrolytes (potassium, magnesium) before and during bowel preparation in patients receiving isoproterenol, and correct deficits promptly.
What to ask your pharmacist
