Does Temazepam Show Up on a Drug Test?
Evidence-based answer reviewed against SAMHSA cutoffs and FDA assay documentation · Updated September 2026
Quick answer: No — not on any standard panel. Temazepam is absent from routine 5-, 10-, and 12-panel employment drug tests. Expanded-panel urine screens commonly at 300 ng/mL (oxazepam equivalent) with 200 ng/mL confirmation.
Which panels screen for it
| Panel | Temazepam status |
|---|---|
| 5-Panel | ❌ Not included |
| 10-Panel | ✅ Included |
| 12-Panel | ✅ Included |
| DOT 5-panel (safety-sensitive) | ❌ Not included |
The details that matter
Temazepam is an intermediate-acting benzodiazepine (half-life ~8–20 hours) that metabolizes to oxazepam — the very compound most benzo immunoassays are calibrated against. It is reliably detected on 10/12-panel benzo strips.
Detection is typical for the class: a few days in urine for occasional use. A valid prescription verifies as negative through the MRO.
Because tolerance builds with regular use, stopping abruptly before a test can be medically risky — medical advice beats test strategy.
If it IS detected, how long does it last?
| Test type | Typical Temazepam detection window |
|---|---|
| Urine | short_acting: 2–4 days |
| Saliva (Mouth Swab) | any: 1–3 days |
| Hair Follicles | up to 90 days |
| Blood | any: 1–2 days |
False-positive notes
- Sertraline and oxaprozin have documented case-report false positives for benzodiazepine immunoassays (class-wide).
Remember: immunoassay screens produce artifacts; mass-spec confirmation and the MRO review are where legitimate explanations win.

Does Temazepam Show up on a Drug Test?
No — standard employment panels don't include Temazepam. Only specialized orders reach it.
How accurate are drug tests?
Lab-based immunoassay screens agree with confirmation testing ~97% of the time; confirmed GC–MS results are considered definitive. Home kits trade legal defensibility for convenience.
Do prescriptions count against me?
No — verified prescriptions report as negative through the Medical Review Officer. Declare medications at collection and answer the follow-up call.
