These medicines both target the same pathway for blood pressure control, which increases the risk of kidney failure and high potassium. Using them together can cause your blood pressure to fall to unsafe levels.
FDA Label Information
7.4 Dual Blockade of the Renin-Angiotensin System (RAS) Dual Blockade of the RAS with angiotensin receptor blockers, ACE inhibitors, or aliskiren is associated with increased risks of hypotension, hyperkalemia, and changes in renal function (including acute renal failure) compared to monotherapy. Do not coadminister aliskiren with benazepril hydrochloride in patients with diabetes. Avoid use of aliskiren with benazepril hydrochloride in patients with renal impairment (GFR < 60 ml/min).
