Summary
Dichlorphenamide promotes urinary potassium loss and can cause hypokalemia and metabolic acidosis. Bowel-cleansing PEG-electrolyte solutions cause fluid and electrolyte shifts and may add to potassium depletion. Combined use may worsen hypokalemia and dehydration.
What this interaction means in plain words
Dichlorphenamide and Polyethylene glycol and electrolytes 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 potassium loss through carbonic anhydrase inhibition (renal kaliuresis) and bowel-prep fluid and electrolyte shifts.
What to do
Check serum potassium and bicarbonate before and after bowel preparation in patients taking dichlorphenamide. Correct hypokalemia and ensure adequate hydration.
