Summary
Non-acetylated salicylates have weaker prostaglandin effects than NSAIDs but may still reduce the antihypertensive effect of atenolol at high doses. The clinical impact is usually small.
What this interaction means in plain words
Atenolol 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
Possible inhibition of renal prostaglandin synthesis leading to sodium retention, which is weaker with non-acetylated salicylates.
What to do
Monitor blood pressure if high-dose salicylates are used for prolonged periods, and adjust antihypertensive therapy if control worsens.
What to ask your pharmacist
- Is there anything I should notice while taking both?
- Do I need to tell my doctor at the next visit?
