Summary
Corticosteroids and loop diuretics can both lower serum potassium. With inhaled mometasone the systemic effect is small, so significant hypokalemia is unlikely except at high doses or with other risk factors.
What this interaction means in plain words
Furosemide and Mometasone have a small, usually unimportant interaction. Most people can take both; the pharmacist may still mention it so that any unexpected effect is recognised.
Furosemide belongs to Cardiovascular; Mometasone belongs to Respiratory.
Why it happens
Additive renal potassium wasting; limited by low systemic exposure from inhaled mometasone.
What to do
Monitor serum potassium in patients with additional risk factors such as high steroid doses or digoxin use. No routine adjustment is needed.

- Is there anything I should notice while taking both?
