Summary
Metaproterenol, a beta-agonist, can lower serum potassium by shifting it into cells. This effect is generally modest with this combination, since telmisartan tends to raise potassium, but it can be relevant at high doses of the beta-agonist.
What this interaction means in plain words
Metaproterenol and Telmisartan-amlodipine 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
Beta-2 agonist stimulation of cellular potassium uptake; the antihypertensive combination has little direct opposing effect.
What to do
No routine action is needed. Check serum potassium if high or frequent doses of metaproterenol are used or other hypokalemia risk factors are present.
