Summary
NSAIDs can blunt the antihypertensive and diuretic effects of thiazides and increase the risk of renal impairment, particularly with volume depletion. The potassium effects oppose each other, so the key concern is reduced efficacy and kidney injury.
What this interaction means in plain words
Etodolac 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 reduced renal perfusion, antagonizing the diuretic effect.
What to do
Monitor blood pressure, fluid status and serum creatinine and electrolytes, and ensure adequate hydration. Use the lowest effective NSAID dose for the shortest time.
What to ask your pharmacist
