Summary
Potassium iodide contains potassium, which can add to the hyperkalemic tendency of olmesartan. Risk is mainly relevant with prolonged or high-dose iodide use or reduced kidney function.
What this interaction means in plain words
Olmesartan and Potassium iodide 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.
Olmesartan belongs to Cardiovascular; Potassium iodide belongs to Endocrine.
Why it happens
Reduced aldosterone-dependent potassium excretion from angiotensin receptor blockade combined with additional potassium intake.
What to do
Monitor serum potassium if potassium iodide is used for more than a short course, especially in renal impairment. Reduce or stop the iodide if hyperkalemia occurs.
