Oxycodone Drug Test Guide: Panels, Detection Windows & More
Evidence-based answer reviewed against SAMHSA cutoffs and FDA assay documentation · Updated August 2026
Quick answer: Semi-synthetic opioid agonist — not included on the federal 5-panel. Urine detects it roughly 1–3 days; hair archives ~90 days; saliva and blood track only recent use. Expanded urine: 100 ng/mL initial/confirm (oxycodone or noroxycodone).
Overview
This guide covers everything verifiable about how testing handles Oxycodone (oxycodone-acetaminophen tablets, extended-release oxycodone) (also searched as: oxycodone-acetaminophen tablets, extended-release oxycodone, oxycodone-acetaminophen tablets, roxicodone): which panels include it, detection windows across specimens, cutoff levels, false-positive risks, and legitimate prescription handling.
Panel membership
| Panel | Oxycodone status |
|---|---|
| 5-Panel | ❌ Not included |
| 10-Panel | ✅ Included |
| 12-Panel | ✅ Included |
| DOT 5-panel (safety-sensitive) | ❌ Not included |
Detection windows
| Test type | Typical Oxycodone detection window |
|---|---|
| Urine | occasional: 1–3 days · regular: 3–4 days |
| Saliva (Mouth Swab) | any: 1–2 days |
| Hair Follicles | up to 90 days |
| Blood | any: ~24 hours |
Cutoff levels
Expanded urine: 100 ng/mL initial/confirm (oxycodone or noroxycodone).
Cutoffs exist to separate real use from noise — dietary exposure, passive contact and legacy medications stay below them by design. Screen-above-cutoff results still require mass-spec confirmation before reporting.
Deep-dive facts
oxycodone-acetaminophen tablets contains oxycodone plus acetaminophen; the acetaminophen is irrelevant to testing. Oxycodone needs its own assay slot — legacy 5-panel opiate tests (morphine/codeine-focused at 2,000 ng/mL) often miss it, which is why 10/12-panel cups add an OXY strip.
A valid prescription verifies as negative through the MRO; keep the bottle or pharmacy record handy during hiring screenings.
Extended-release formulations (extended-release oxycodone) linger marginally longer than instant-release oxycodone-acetaminophen tablets.
False positives & cross-reactivity
- No significant oxycodone false positives documented on modern assays; poppy seeds affect morphine/codeine results, not oxycodone strips.
| Screen flagged | Documented cross-reactants (immunoassay tier only) |
|---|---|
| Amphetamines | Bupropion (bupropion), trazodone, phentermine, pseudoephedrine, labetalol, promethazine, methylphenidate |
| PCP | Dextromethorphan (dextromethorphan cough syrup), diphenhydramine (diphenhydramine), doxylamine (multi-symptom cold remedies), tramadol, venlafaxine (venlafaxine), ketamine |
| Opiates | Poppy seeds (true positive), quinine, dextromethorphan, ofloxacin/levofloxacin, rifampin |
| Benzodiazepines | Sertraline (sertraline), oxaprozin (case reports) |
| Methadone | Diphenhydramine, doxylamine, verapamil, quetiapine (quetiapine), clomipramine |
| Tricyclics (TCA) | Cyclobenzaprine (cyclobenzaprine), hydroxyzine, carbamazepine, diphenhydramine |
| Cannabinoids (THC) | Efavirenz, pantoprazole (isolated reports); dronabinol/dronabinol = true positive |
Legal status note
Schedule II by prescription.
