Summary
NSAIDs can reduce renal potassium excretion by suppressing renin and aldosterone via prostaglandin inhibition. Together with potassium phosphate supplementation this may cause hyperkalemia, especially in renal impairment or with other potassium-raising drugs.
What this interaction means in plain words
Naproxen 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 hyporeninemic hypoaldosteronism and reduced renal potassium excretion add to potassium load.
What to do
Monitor serum potassium and renal function, especially in the elderly or patients with kidney disease or on ACE inhibitors. Adjust the potassium dose accordingly.
What to ask your pharmacist
- Should I take them at different times of day?
- Does the dose of either medicine need to change?
- Is there anything I should avoid, such as alcohol or certain foods, while on both?
