Summary
Non-acetylated salicylates have weaker prostaglandin inhibition than other NSAIDs but may still modestly reduce the antihypertensive effect of labetalol with prolonged use. The effect is usually small and variable.
What this interaction means in plain words
Labetalol 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
Inhibition of renal prostaglandin synthesis may cause sodium and fluid retention that opposes beta-blocker antihypertensive action.
What to do
Check blood pressure periodically during long-term salicylate use and adjust the antihypertensive regimen 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?
