Lisinopril and Aliskiren Interaction

Drug interaction information between Lisinopril and Aliskiren.

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

FDA drug labeling documents a major-severity interaction between Lisinopril and Aliskiren. 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

Lisinopril

ACE Inhibitor

Drug B

Aliskiren

Direct Renin Inhibitor

How They Interact

Both medicines target the same body system to lower blood pressure, which can lead to dangerously low blood pressure or kidney damage.

What To Do

This combination should be avoided, especially if you have diabetes or kidney issues, to prevent serious health risks.

FDA Label Information

Dual Blockade of the Renin-Angiotensin System (RAS): Dual blockade of the RAS with angiotensin receptor blockers, ACE inhibitors, or direct renin inhibitors (such as aliskiren) is associated with increased risk of hypotension, syncope, hyperkalemia, and changes in renal function (including acute renal failure) compared to monotherapy. Do not coadminister aliskiren with lisinopril and hydrochlorothiazide tablets in patients with diabetes. Avoid use of aliskiren with PRINZIDE in patients with renal impairment (GFR <60 ml/min).

Frequently Asked Questions

Can I take Lisinopril and Aliskiren together?

This is a major interaction. This combination should be avoided, especially if you have diabetes or kidney issues, to prevent serious health risks.

How serious is the interaction between Lisinopril and Aliskiren?

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

Why do Lisinopril and Aliskiren interact?

Both medicines target the same body system to lower blood pressure, which can lead to dangerously low blood pressure or kidney damage.

Understanding the Lisinopril and Aliskiren Interaction

FDA-approved prescribing information for these two drugs flags their combination as a major-severity interaction. Lisinopril 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: Both medicines target the same body system to lower blood pressure, which can lead to dangerously low blood pressure or kidney damage. 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. Lisinopril has 15 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 be avoided, especially if you have diabetes or kidney issues, to prevent serious health risks. 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 Lisinopril or Aliskiren based on a web page, speak with your prescriber or pharmacist before making any change.
