Summary
NSAIDs can blunt the antihypertensive and diuretic effects of thiazides and, with volume depletion, raise the risk of acute kidney injury.
What this interaction means in plain words
Fenoprofen and Methyclothiazide 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
NSAID inhibition of renal prostaglandins causes sodium and water retention and decreased renal perfusion, opposing thiazide effects.
What to do
Monitor blood pressure, renal function and electrolytes, keep patients hydrated, and adjust antihypertensive therapy if control worsens.
What to ask your pharmacist
- Should I take them at different times of day?
- Does the dose of either medicine need to change?
