Summary
Both drugs can lower serum potassium, and the effect may be additive. Significant hypokalemia increases the risk of cardiac arrhythmias, especially in patients with heart disease or those taking other QT-prolonging drugs.
What this interaction means in plain words
Dexamethasone and Indacaterol 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.
Dexamethasone belongs to Endocrine; Indacaterol belongs to Respiratory.
Why it happens
Beta-2 agonists shift potassium into cells while corticosteroids promote renal potassium loss, producing additive hypokalemia.
What to do
Monitor serum potassium, particularly with high-dose or prolonged corticosteroid therapy or in acute illness. Replace potassium as needed.
