Summary
Potassium acid phosphate supplies potassium, and NSAIDs reduce renal potassium excretion by suppressing renin and aldosterone. Hyperkalemia is more likely in renal impairment, diabetes or with other potassium-raising drugs.
What this interaction means in plain words
Flurbiprofen 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
Additive potassium load with NSAID-induced hyporeninemic hypoaldosteronism and reduced renal potassium excretion.
What to do
Monitor serum potassium and renal function, especially in at-risk patients, and adjust the potassium dose accordingly.
