Summary

Potassium iodide contains potassium that can add to the potassium retention caused by benazepril. Hyperkalemia is possible, especially with prolonged use or reduced kidney function.

What this interaction means in plain words

Benazepril 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.

Benazepril belongs to Cardiovascular; Potassium iodide belongs to Endocrine.

Evidence level: Low

Why it happens

ACE inhibitor-induced aldosterone suppression reduces potassium excretion, adding to the potassium delivered by the iodide salt.

What to do

For short courses the risk is small, but monitor serum potassium if potassium iodide is used repeatedly or in patients with renal impairment.
