How long does oxycodone take to work?
Immediate-release oxycodone starts to work quickly, within 10 to 30 minutes, but it may take up to 1 hour for it to be fully absorbed, and the full effects reached. Food can delay how quickly oxycodone takes to work, but not how much is absorbed.
Controlled or extended-release Oxycontin, which also contains oxycodone, releases oxycodone more slowly, and it can take up to 1 hour to start working.

How long does oxycodone stay in your system?
Immediate-release oxycodone has a half-life of just under 4 hours which means the pain-relieving effects of one dose will be gone within 6 to 24 hours, but it can remain detectable in saliva, urine, and hair for much longer. In saliva, oxycodone is detectable within minutes of taking it and lasts for up to 48 hours (2 days). Oxycodone is detectable in urine within 1 to 3 hours and will stay detectable for 1 to 4 days. Like most other opioids, oxycodone is detectable in hair for up to 90 days. Continue reading
