Summary

NSAIDs can reduce the diuretic and antihypertensive effect of thiazide-like diuretics such as metolazone. Concurrent use may also raise the risk of renal impairment in volume-depleted patients.

What this interaction means in plain words

Meclofenamic acid and Metolazone 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.

Meclofenamic acid belongs to Musculoskeletal; Metolazone belongs to Cardiovascular.

Evidence level: Moderate

Why it happens

NSAID inhibition of renal prostaglandins causes sodium and water retention and reduced renal blood flow, opposing diuretic action.

What to do

Monitor blood pressure, weight or edema, and renal function, and maintain hydration. Adjust the diuretic dose or choose a non-NSAID analgesic if response is lost.

What to ask your pharmacist

  • Should I take them at different times of day?
  • Does the dose of either medicine need to change?
  • Is there anything I should avoid, such as alcohol or certain foods, while on both?
