Benazepril and Aliskiren Interaction

Understanding the Benazepril and Aliskiren Interaction

FDA-approved prescribing information for these two drugs flags their combination as a major-severity interaction. Benazepril belongs to the ACE Inhibitor class and Aliskiren belongs to the Direct Renin 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. Benazepril has 5 total documented interactions on file in this dataset, and Aliskiren has 28. 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.

Never start, stop, or adjust either Benazepril or Aliskiren based on a web page, speak with your prescriber or pharmacist before making any change.
