Summary
Phosphate and potassium-containing supplements can raise serum potassium, and NSAIDs such as ketorolac can reduce renal potassium excretion. Together this may produce hyperkalemia, especially in patients with renal impairment.
What this interaction means in plain words
Ketorolac 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.
Why it happens
NSAID-induced suppression of renin-aldosterone axis and reduced renal potassium excretion adds to potassium load.
What to do
Monitor serum potassium and renal function, especially in patients with kidney disease or on other potassium-raising drugs.
What to ask your pharmacist
