Darunavir and Triazolam Interaction

Drug interaction information between Darunavir and Triazolam.

Darunavir and Triazolam have a documented major interaction in FDA labeling.

FDA drug labeling documents a major-severity interaction between Darunavir and Triazolam. 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

Darunavir

HIV Protease Inhibitor

Drug B

Triazolam

Benzodiazepine (Hypnotic)

How They Interact

Darunavir blocks the body from breaking down triazolam, which can cause the sedative to build up to dangerous levels. This can lead to extreme sleepiness or trouble breathing.

What To Do

Do not take these two medications together because the combination can be life-threatening.

FDA Label Information

Sedatives/hypnotics: orally administered midazolam, triazolam ↑ midazolam ↑ triazolam Co-administration is contraindicated due to potential for serious and/or life-threatening reactions such as prolonged or increased sedation or respiratory depression. Triazolam and orally administered midazolam are extensively metabolized by CYP3A. Co-administration of triazolam or orally administered midazolam with darunavir may cause large increases in the concentrations of these benzodiazepines.

Frequently Asked Questions

Can I take Darunavir and Triazolam together?

This is a major interaction. Do not take these two medications together because the combination can be life-threatening.

How serious is the interaction between Darunavir and Triazolam?

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

Why do Darunavir and Triazolam interact?

Darunavir blocks the body from breaking down triazolam, which can cause the sedative to build up to dangerous levels. This can lead to extreme sleepiness or trouble breathing.

Understanding the Darunavir and Triazolam Interaction

FDA-approved prescribing information for these two drugs flags their combination as a major-severity interaction. Darunavir belongs to the HIV Protease Inhibitor class and Triazolam belongs to the Benzodiazepine (Hypnotic) class - two categories that can collide when co-prescribed. The mechanism described in FDA labeling is: Darunavir blocks the body from breaking down triazolam, which can cause the sedative to build up to dangerous levels. 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. Darunavir has 101 total documented interactions on file in this dataset, and Triazolam has 10. 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: Do not take these two medications together because the combination can be life-threatening. 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 Darunavir or Triazolam based on a web page, speak with your prescriber or pharmacist before making any change.
