Summary
Parecoxib, through its active metabolite valdecoxib, can reduce the antihypertensive effect of beta-blockers and cause fluid retention and renal impairment. Blood pressure may rise with continued use.
What this interaction means in plain words
Nadolol and Parecoxib can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken.
Why it happens
COX-2 inhibition reduces renal prostaglandins, causing sodium and water retention that opposes blood pressure lowering.
What to do
Monitor blood pressure and renal function if used beyond a short perioperative course. Use the lowest effective dose for the shortest duration.
