Trazodone and Linezolid Interaction

Drug interaction information between Trazodone and Linezolid.

Trazodone and Linezolid have a documented major interaction in FDA labeling.

FDA drug labeling documents a major-severity interaction between Trazodone and Linezolid. 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

Trazodone

Serotonin Antagonist and Reuptake Inhibitor (SARI)

Drug B

Linezolid

Oxazolidinone Antibiotic

How They Interact

Linezolid acts like a special type of medicine that can cause a dangerous buildup of a brain chemical called serotonin when mixed with trazodone. This can lead to a serious condition called serotonin syndrome.

What To Do

Do not take these two medications together. Your doctor will need to find an alternative treatment for you.

Understanding the Trazodone and Linezolid Interaction

FDA-approved prescribing information for these two drugs flags their combination as a major-severity interaction. Trazodone belongs to the Serotonin Antagonist and Reuptake Inhibitor (SARI) class and Linezolid belongs to the Oxazolidinone Antibiotic class - two categories that can collide when co-prescribed. The mechanism described in FDA labeling is: Linezolid acts like a special type of medicine that can cause a dangerous buildup of a brain chemical called serotonin when mixed with trazodone. 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. Trazodone has 40 total documented interactions on file in this dataset, and Linezolid has 29. 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. 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 Trazodone or Linezolid based on a web page, speak with your prescriber or pharmacist before making any change.
