Summary

Potassium phosphate supplements add a potassium load, and NSAIDs can reduce renal potassium excretion by suppressing renin and aldosterone. This may cause hyperkalemia, especially in renal impairment or with other potassium-raising drugs.

What this interaction means in plain words

Ketoprofen and Potassium 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.

Evidence level: Moderate

Why it happens

NSAID-induced hyporeninemic hypoaldosteronism and reduced renal function decrease potassium excretion on top of added potassium intake.

What to do

Monitor serum potassium and renal function, particularly in elderly patients or those with kidney disease; adjust the potassium dose as needed.

What to ask your pharmacist

  • Should I take them at different times of day?
  • Does the dose of either medicine need to change?
