How Long Does Oxycodone Stay in Your system (all test types)?
Evidence-based answer reviewed against SAMHSA cutoffs and FDA assay documentation · Updated August 2026
Quick answer: Most people clear Oxycodone from your system (all test types) within varies by usage pattern of last use — heavy or daily use stretches that window substantially. Expanded urine: 100 ng/mL initial/confirm (oxycodone or noroxycodone).
Oxycodone detection windows by test type
Each specimen tells a different story because each samples different biology:
| 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 |
('Detection windows differ dramatically by specimen type because each matrix captures different biology: urine accumulates EXCRETED metabolites for days, saliva traps recent parent-drug residue for hours-to-days, hair archives bloodstream exposure for months, and blood measures active circulation almost in real-time.',)
Why detection works this way
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.
Testing cutoffs in plain language
Expanded urine: 100 ng/mL initial/confirm (oxycodone or noroxycodone). A specimen under the initial cutoff reports negative without further work; a screen above cutoff gets confirmed by mass spectrometry before anyone sees a positive.
