Brief Answer: Depends on how much the patient has been taking Detailed Answer: Hi It all depends upon how often you take Oxycontin or Oxycodone. If you just tried your first time,normal results would say it's out of your urine within 2-4 days, blood about 3 days (upto 5) , depending upon the dosage and the size,weight of the person. For people prescribed Oxycontin daily,esp. in high milligram amounts, the drug would be present from 6 days up to 2 weeks. The number of hours after a mother's last dose when oxycodone could still be measured in milk depends on the number of doses taken. Oxycodone can be detected for upto 36 hours in breast milk in chronic users. I hope this helps. Vinay
