Summary
Non-acetylated salicylates have weaker prostaglandin inhibition than other NSAIDs, so interference with metoprolol's antihypertensive effect is likely small. Blood pressure control may be slightly affected with regular high doses.
What this interaction means in plain words
Metoprolol and Salicylates 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
Prostaglandin inhibition causing mild sodium and fluid retention that can oppose the antihypertensive effect.
What to do
Monitor blood pressure if high-dose salicylates are used regularly. No routine dose change is needed.
