Summary

NSAIDs can blunt the antihypertensive and diuretic effects of thiazides and, together with diuretics, increase the risk of acute kidney injury, especially in dehydrated or elderly patients.

What this interaction means in plain words

Ketoprofen 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.

Evidence level: High

Why it happens

NSAID inhibition of renal prostaglandins causes sodium and water retention and reduced renal perfusion, opposing the thiazide.

What to do

Monitor blood pressure, renal function and electrolytes, and ensure adequate hydration; adjust antihypertensive therapy or limit NSAID use if control worsens.

What to ask your pharmacist

  • Should I take them at different times of day?
