Oxycodone stays in the body for around four to five days after use. It is all dependent on the metabolic rate. If it is high, the oxydocone will be out of the body in the form of urine in around two to three days. If you drink many liquids, the oxydocone is bound to be eliminated from your body soon.
Oxycodone can be detected in our urine for up to 4 days if you are not a heavy user. If you have used heavily or taking a high dosage, it can take up to six weeks for it be undetectable in your urine. Look here for more information: http://www.drugs.com/oxycontin.html.
