Summary
NSAIDs can reduce renal potassium excretion and cause hyperkalemia, and potassium phosphate supplements add a potassium load. The risk is greater with renal impairment, diabetes or other potassium-raising drugs.
What this interaction means in plain words
Potassium acid and Sulindac 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 prostaglandin-mediated renin and aldosterone release reduces renal potassium excretion, adding to the supplemental potassium.
What to do
Monitor serum potassium and renal function, especially at initiation and in patients with kidney disease. Adjust the potassium dose as needed.
What to ask your pharmacist
