Oxycodone is a powerful prescription opioid commonly sold under brand names like OxyContin and Percocet, used to treat moderate to severe pain. It is one of the most widely misused prescription drugs in the United States, and like all opioids, it remains detectable in the body for some time after its effects have worn off. The detection times for oxycodone depends on which testing method is used and a range of personal factors.
Blood testing has the shortest detection window of all drug test types, capable of identifying oxycodone use for up to 24 hours after the last dose. For a longer detection window, urine testing can detect oxycodone for up to four days, while hair follicle testing has the broadest reach at up to 90 days after last use.
How Long Can Oxycodone Be Detected In Blood?
On average, oxycodone use can be detected in a blood sample for up to 24 hours after the last dose. Because of this short window, blood tests are most commonly used in emergency or clinical settings where very recent oxycodone use needs to be confirmed quickly, such as following a suspected overdose, a motor vehicle accident, or when a person is showing signs of acute intoxication.
Blood tests detect oxycodone itself rather than just its metabolites, which is one reason the detection window is shorter than with urine or hair testing. As the body metabolizes and eliminates the drug, blood concentration levels drop rapidly often falling below detectable thresholds within a day for most people.
Factors That Can Affect Oxycodone Detection Times
Although oxycodone will generally stay in your blood for no more than 24 hours, some factors may affect this. The actual timeline can vary according to a variety of factors.
Factors that can affect how long oxycodone stays in blood:
- amount taken
- formulation (i.e. immediate release vs. extended-release)
- duration of use
- frequency of use
- method of use (e.g. snorting vs. swallowing)
- metabolic rate
- body fat percentage
- impaired liver and kidney function
These factors can help explain why detection times vary from person to person even when the same dose is taken under similar conditions.
Getting Oxycodone Out Of Your Blood
Oxycodone is a common drug of abuse. If you or a loved one is misusing oxycodone, it may be difficult to stop taking it long enough to get a negative drug test result.
Quitting oxycodone cold-turkey carries a high risk for relapse and accidental overdose. The safest way to get off oxycodone and get help for drug abuse is to begin a drug treatment program.
Find Treatment For Oxycodone Addiction
Oxycodone addiction is a serious medical condition, and attempting to stop without professional support increases the risk of dangerous withdrawal symptoms and relapse. Because tolerance drops quickly after stopping, relapse following a period of abstinence increases the risk of accidental overdose, making medically supervised detox the recommended first step for anyone who has been using oxycodone for an extended period.
Following detoxification, opioid addiction treatment options may include medication-assisted treatment using buprenorphine or methadone to manage cravings and stabilize brain chemistry, residential or outpatient programs, behavioral therapies, dual diagnosis treatment, 12-step meetings, and aftercare.
