What the FDA labels say
From the Amlodipine and benazepril (Amlodipine and Benazepril Hydrochloride) label · effective 2026-01-29
Symptomatic hypotension is most likely to occur in patients who have heart failure, severe aortic or mitral stenosis, obstructive hypertrophic cardiomyopathy or have been volume or salt depleted as a result of diuretic therapy, dietary salt restriction, dialysis, diarrhea, or vomiting.
In patients with congestive heart failure, start amlodipine and benazepril hydrochloride therapy under close medical supervision; follow closely for the first 2 weeks of treatment and whenever the dose of the benazepril component is increased or a diuretic is added or its dose increased.
Risk factors for the development of hyperkalemia include renal insufficiency, diabetes mellitus, and the concomitant use of potassium-sparing diuretics, potassium supplements, and/or potassium-containing salt substitutes.
Potassium supplements/potassium-sparing diuretics: hyperkalemia ( 7.1 )
Potassium-sparing diuretics (spironolactone, amiloride, triamterene, and others) or potassium supplements can increase the risk of hyperkalemia.
From the Furosemide label · effective 2026-05-13
Angiotensin converting enzyme inhibitors or angiotensin II receptor blockers May lead to severe hypotension and deterioration in renal function, including renal failure.
Monitor for changes in blood pressure and renal function and interrupt or reduce the dosage of furosemide, angiotensin converting enzyme inhibitors, or angiotensin receptor blockers if needed.
Monitor for changes in blood pressure and adjust the dose of other antihypertensive drugs if needed.
