Oxycodone typically stays in your system for up to 24 hours, but traces can remain longer depending on dosage, metabolism, and frequency of use. In urine, it’s detectable for 1–4 days; in blood for up to 24 hours; in saliva for 1–2 days; and in hair for up to 90 days. Factors like age, liver function, and hydration also affect how long it remains detectable. Always consult a medical professional for personalized information regarding detection and safety.
