Summary
Thiazide diuretics cause potassium loss, and beta-2 agonists can further lower serum potassium. The additive hypokalemia may provoke arrhythmias, especially with high-dose formoterol or heart disease.
What this interaction means in plain words
Bendroflumethiazide and Formoterol-mometasone 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 through renal potassium loss and beta-2-mediated cellular potassium uptake.
What to do
Monitor serum potassium and replace if low. Use extra care in patients with cardiac disease or on digoxin.
