Summary
Systemic dexamethasone can cause potassium loss, and olodaterol can further lower serum potassium by shifting it into cells. Together they may produce hypokalemia that predisposes to arrhythmias.
What this interaction means in plain words
Dexamethasone and Tiotropium-olodaterol 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 mineralocorticoid-related renal loss and beta2-mediated intracellular shift.
