Summary
Prolonged NSAID use can blunt the antihypertensive effect of beta-blockers, so blood pressure control may worsen.
What this interaction means in plain words
Betaxolol and Mefenamic acid 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.
Betaxolol belongs to Cardiovascular; Mefenamic acid belongs to Musculoskeletal.
Why it happens
NSAID-mediated prostaglandin inhibition causes sodium and fluid retention and vasoconstriction, opposing beta-blocker effect.
What to do
Monitor blood pressure if NSAID therapy exceeds a week and adjust the antihypertensive regimen as needed. Use the lowest effective NSAID dose.
