Summary
NSAIDs such as parecoxib can reduce the blood pressure lowering effect of beta-blockers like atenolol. The effect is more relevant with sustained use and in patients with hypertension or renal impairment.
What this interaction means in plain words
Atenolol 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
Inhibition of renal prostaglandin synthesis causes sodium and fluid retention and counteracts the antihypertensive effect.
What to do
Monitor blood pressure when parecoxib is given for more than a few days, and use the lowest effective dose for the shortest time. Consider adjusting antihypertensive therapy or using a non-NSAID analgesic.
What to ask your pharmacist

- Is there anything I should avoid, such as alcohol or certain foods, while on both?
