Routine potassium supplementation should be avoided. Ensure regular serum potassium monitoring. Educate patients to recognize hyperkalemia symptoms such as muscle weakness, palpitations, and fatigue.
Why this interaction occurs
Benazepril suppresses the renin-angiotensin-aldosterone system, reducing renal potassium elimination. Concurrent use of potassium supplements can rapidly elevate potassium to dangerous levels, particularly in patients with underlying chronic kidney disease, who are already predisposed to impaired potassium clearance.
Evidence
Evidence level: strong.
