Amlodipine and benazepril and Candesartan: both prescribing labels flag this combination with the strongest language, such as a contraindication, a boxed warning, or an instruction to avoid it.
Do not combine without a prescriber's guidance. The label language below is the strongest FDA uses.
What the FDA labels say
From the Amlodipine and benazepril (Amlodipine and Benazepril Hydrochloride) label · effective 2026-01-29
Do not coadminister aliskiren with angiotensin receptor blockers (ARBs), angiotensin-converting enzyme (ACE) inhibitors, including amlodipine and benazepril hydrochloride capsules in patients with diabetes.
Patients whose renal function may depend in part on the activity of the RAS (e.g., patients with renal artery stenosis, severe heart failure, post-myocardial infarction or volume depletion) or who are on Nonsteroidal Anti-Inflammatory Drugs (NSAIDs) or ARBs may be at particular risk of developing acute renal failure on amlodipine and benazepril hydrochloride.
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.
From the Candesartan (Candesartan cilexetil) label · effective 2026-01-15
Triple combination of candesartan cilexetil with an ACE-inhibitor and a mineralocorticoid receptor antagonist is generally not recommended.
In the CHARM-Added program, where candesartan or placebo was given in addition to ACE inhibitors, hypotension was reported in 22.6% of patients treated with candesartan cilexetil versus 13.8% treated with placebo [see Drug Interactions (7.3) ] .
In the CHARM-Added program, where candesartan or placebo was given in addition to ACE inhibitors, the incidence of abnormal renal function (e.g., creatinine increase) was 15% in patients treated with candesartan cilexetil versus 9% in patients treated with placebo [see Drug Interactions (7.3) ] .
In the CHARM-Added program where candesartan or placebo was given in addition to ACE inhibitors, the incidence of hyperkalemia was 9.5% in patients treated with candesartan cilexetil versus 3.5% in patients treated with placebo [see Drug Interactions (7.1) ] .
Combination 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.
