Aliskiren and Benazepril Interaction

Drug interaction information between Aliskiren and Benazepril.

Aliskiren and Benazepril have a documented major interaction in FDA labeling.

FDA drug labeling documents a major-severity interaction between Aliskiren and Benazepril. Major interactions are generally avoided, moderate ones may need monitoring or a dose adjustment, and minor ones are usually low-risk. This page shows the documented mechanism and guidance. Label-documented interactions are not a complete safety review, so always confirm your own medications with a pharmacist or doctor. Educational information, not medical advice.

Drug A

Aliskiren

Direct Renin Inhibitor

Drug B

Benazepril

ACE Inhibitor

How They Interact

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.

What To Do

This combination should not be used in patients with diabetes or kidney disease. Talk to your doctor about using only one of these medications to protect your kidneys.

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).

Frequently Asked Questions

Can I take Aliskiren and Benazepril together?

This is a major interaction. This combination should not be used in patients with diabetes or kidney disease. Talk to your doctor about using only one of these medications to protect your kidneys.

How serious is the interaction between Aliskiren and Benazepril?

This interaction is classified as "major" severity by the FDA. Major interactions may be life-threatening or cause serious side effects.

Why do Aliskiren and Benazepril interact?

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.

Understanding the Aliskiren and Benazepril Interaction

FDA-approved prescribing information for these two drugs flags their combination as a major-severity interaction. Aliskiren belongs to the Direct Renin Inhibitor class and Benazepril belongs to the ACE Inhibitor class - two categories that can collide when co-prescribed. The mechanism described in FDA labeling is: These medicines both target the same pathway for blood pressure control, which increases the risk of kidney failure and high potassium. Severity tiers matter: major flags generally advise avoidance, moderate flags often require monitoring or dose adjustment, and minor flags may only call for awareness.

Context around a specific patient determines real-world impact. Aliskiren has 28 total documented interactions on file in this dataset, and Benazepril has 5. Each additional medication compounds the interaction surface, which is why pharmacists run full-profile checks rather than evaluating one pair at a time. FDA-derived guidance for this pair is: This combination should not be used in patients with diabetes or kidney disease. Timing of doses, renal and hepatic function, age, and other concurrent prescriptions all shape whether a labeled interaction matters clinically.

An interaction flag is not a verdict. A large share of labeled interactions are managed routinely in clinical practice, the fix may be as simple as spacing doses or adding a monitoring test. Others require the prescriber to choose a different medication entirely. This page surfaces FDA-sourced labeling and openFDA data for educational purposes only; it is not medical advice and cannot account for your full clinical picture. Never start, stop, or adjust either Aliskiren or Benazepril based on a web page, speak with your prescriber or pharmacist before making any change.
