Summary
Potassium iodide supplies potassium and NSAIDs can reduce renal potassium excretion, so serum potassium may rise, especially with renal impairment or other potassium-raising drugs. With short-course or low-dose use the effect is usually small.
What this interaction means in plain words
Naproxen and Potassium iodide have a small, usually unimportant interaction. Most people can take both; the pharmacist may still mention it so that any unexpected effect is recognised.
Naproxen belongs to Musculoskeletal; Potassium iodide belongs to Endocrine.
Why it happens
NSAIDs reduce renin and aldosterone-mediated renal potassium excretion, adding to the potassium load.
What to do
Check serum potassium if therapy is prolonged or in patients with renal impairment or on other potassium-raising drugs.
