Aliskiren and Amlodipine/Benazepril Interaction

Drug interaction information between Aliskiren and Amlodipine/Benazepril.

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

FDA drug labeling documents a major-severity interaction between Aliskiren and Amlodipine/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

Amlodipine/Benazepril

Calcium Channel Blocker / ACE Inhibitor Combination

How They Interact

Both of these drugs target the same system that controls blood pressure, which can cause your blood pressure to drop too low. This combination also increases the risk of kidney damage and high potassium levels.

What To Do

Avoid taking these drugs together, especially if you have diabetes or kidney disease. Your doctor will likely choose a different treatment to protect your kidneys.

FDA Label Information

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 Lotrel in patients with diabetes. Avoid use of aliskiren with Lotrel in patients with renal impairment [glomerular filtration rate (GFR) < 60 mL/min].

Frequently Asked Questions

Can I take Aliskiren and Amlodipine/Benazepril together?

This is a major interaction. Avoid taking these drugs together, especially if you have diabetes or kidney disease. Your doctor will likely choose a different treatment to protect your kidneys.

How serious is the interaction between Aliskiren and Amlodipine/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 Amlodipine/Benazepril interact?

Both of these drugs target the same system that controls blood pressure, which can cause your blood pressure to drop too low. This combination also increases the risk of kidney damage and high potassium levels.

Understanding the Aliskiren and Amlodipine/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 Amlodipine/Benazepril belongs to the Calcium Channel Blocker / ACE Inhibitor Combination class - two categories that can collide when co-prescribed. The mechanism described in FDA labeling is: Both of these drugs target the same system that controls blood pressure, which can cause your blood pressure to drop too low. 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 Amlodipine/Benazepril has 7. 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: Avoid taking these drugs together, especially if you have 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 Amlodipine/Benazepril based on a web page, speak with your prescriber or pharmacist before making any change.
