Summary
Potassium acid phosphate supplies potassium, and NSAIDs can reduce renal potassium excretion. The combination can cause hyperkalemia, especially in patients with renal impairment, diabetes or those on other potassium-raising drugs.
What this interaction means in plain words
Oxaprozin 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 and reduced renal potassium excretion add to an exogenous potassium load.
What to do
Monitor serum potassium and renal function, particularly at the start of therapy. Adjust potassium dose if potassium rises.
