Oxycodone can be detected in urine typically for about 1 to 4 days after the last dose. Most sources agree that the common detection window in urine ranges from approximately 2 to 4 days, though it can sometimes be shorter or longer depending on several factors. Details on detection time in urine:
- A study found oxycodone and its metabolites generally detectable in urine within 0–2 hours after dosing, with metabolites peaking within 3–9 hours and detectable for over 24 hours; detection times at common cutoffs (50–150 ng/mL) were 24 hours or more
- On average, oxycodone stays in urine for 2–4 days after the last dose, with some studies noting an average detection time around 30 hours following a single dose
- Other sources state detection in urine can be as short as a few hours up to 3–4 days, depending on dose, metabolism, hydration, and test sensitivity
- The half-life of oxycodone is about 3 to 5 hours, but metabolites like noroxycodone and oxymorphone may extend the detection window in urine
Factors influencing detection time:
- Dosage and frequency of use (higher and repeated doses stay longer)
- Individual metabolism and organ function
- Hydration level (dilution can shorten detection)
- Sensitivity and cutoff levels of the urine test
In summary, oxycodone is usually detectable in urine for about 1 to 4 days after use, with variability based on individual and testing factors. Monitoring both oxycodone and its metabolites improves detection accuracy
