Oxycontin 1 day only: doesn't stay in the blood long-term. The average "half-life" of Oxycontin, which means the time it takes the blood to eliminate half of the drug is 4.5 hours. It takes approximately 6 half lives for a drug to be eliminated from your system 4.5*6/24= 1.12 day. It is important to recognize the signs and symptoms of Oxycontin abuse as early as possible.
