Does Trazodone Show Up on a Drug Test?

Evidence-based answer reviewed against SAMHSA cutoffs and FDA assay documentation · Updated August 2026

Quick answer: Sometimes. Trazodone isn't on every standard panel — coverage depends on panel width and assay configuration. Not directly screened; cross-reacts on some amphetamine immunoassays.

The details that matter

Trazodone doesn't get tested FOR — it can cause amphetamine-strip screen positives in documented case reports. Confirmation testing (GC–MS) shows no amphetamine and closes the loop.

If you take trazodone nightly and receive an unexpected amphetamine screen flag, invoke the MRO review immediately and list trazodone.

If it IS detected, how long does it last?

Ranges reflect occasional-to-heavy use patterns from FDA device inserts and SAMHSA-certified lab conventions.

False-positive notes

  • Amphetamine-screen false positives: case-documented (Francisco & Mehta; Roberge reports).

Remember: immunoassay screens produce artifacts; mass-spec confirmation and the MRO review are where legitimate explanations win.
