Summary
Corticosteroids promote potassium loss and may add to hydrochlorothiazide-induced hypokalemia. With inhaled mometasone, systemic exposure is low, so the effect is usually small.
What this interaction means in plain words
Hydrochlorothiazide-telmisartan and Mometasone inhaled have a small, usually unimportant interaction. Most people can take both; the pharmacist may still mention it so that any unexpected effect is recognised.
Why it happens
Mineralocorticoid-like potassium wasting from systemically absorbed corticosteroid adds to thiazide kaliuresis.
What to do
No routine action is needed at standard inhaled doses; check serum potassium if high doses are used or other potassium-lowering drugs are present.
