Summary
There is no well-established clinically meaningful interaction between indomethacin and formoterol. NSAID effects on potassium mainly arise in renal impairment.
What this interaction means in plain words
Formoterol and Indomethacin have a small, usually unimportant interaction. Most people can take both; the pharmacist may still mention it so that any unexpected effect is recognised.
Formoterol belongs to Respiratory; Indomethacin belongs to Musculoskeletal.
Why it happens
No established mechanism; NSAIDs may rarely raise potassium through reduced renal prostaglandin and renin effects.
What to do
No specific action is needed beyond routine monitoring of potassium in patients with renal impairment or on other potassium-altering drugs.
What to ask your pharmacist
- Is there anything I should notice while taking both?
