Learn more about the effects and uses of oxycodone here. Most people take oxycodone every 6 or 12 hours , depending on the version of the drug they use.
When it is time to take the next dose, most people no longer feel the effects of the drug from the previous dose. The half life of oxycodone is 4. This is the amount of time it takes for the blood concentration of the drug to decrease by half. By the 24 hour mark, blood concentrations of the drug are either very low or nonexistent. This means that most people will get a negative blood test within a day or two of their last dose.
On average, oxycodone stays in the urine for 2—4 days following the last dose. One study found an average duration of 30 hours following a single dose. Hair tests for oxycodone are the most sensitive. This is because it is possible for oxycodone to contaminate the hair even if a person does not use it. Also, oxycodone may remain on the ends of the hair for months or even years after a person stops using it.
Tests of the root of the hair may get a positive result for weeks or months. For example, a newborn drinking only colostrum — that is, the milk produced by the maternal mammary glands during the first few days after giving birth — would get less oxycodone than an infant whose sole source of nutrition is breast milk and who nurses many times each day.
One small study suggests that oxycodone levels in breast milk peak 1—2 hours after the last dose. The same study found detectable levels of oxycodone in breast milk 4, 12, and 36 hours after the last dose, though the concentration in the milk varied.
These data suggest a significant variation in the amount of oxycodone present in breast milk. Most guides suggest that women can still breastfeed if they use oxycodone, but that the dosage should not exceed 30—40 milligrams in a 24 hour period. Oxycodone peaks in the bloodstream 1—2 hours after taking an oral dose. Blood concentrations remain steady for about 6 hours , then they fall rapidly.
This means that most people who depend on oxycodone will begin experiencing withdrawal at around 6 hours. Percocet and Percodan both contain oxycodone and are immediate-release drugs.
OxyContin is an extended-release form of oxycodone. Although oxycodone has valid medical purposes and is prescribed by doctors, it can also be dangerous if abused. Oxycodone has a high propensity for dependence, so people often need formal oxycodone addiction treatment to safely stop misuse once they become addicted to the drug. In some cases, traces of oxycodone may even be found months after it was last taken.
Just how long oxycodone stays in the body and its detection time will depend on a variety of factors and could be different for everyone. Generally, people who use oxycodone long-term or in heavier doses are more likely to have traces of this drug in their bodies for an extended time.
Because traces of the drug can remain in the body long after the effects wear off, oxycodone can be detected by drug tests after the immediate high passes. The exact detection time of oxycodone can vary from person to person and will change based on several factors. Arguably the biggest factor impacting the detection time of oxycodone is the type of drug test used. Different drug tests have different windows of detection and some are more accurate than others.
Because they are noninvasive and easy to execute, urine tests are the most popular way to test for the presence of oxycodone in the body. Generally, the oxycodone detection time of urine is around two to four days. While highly accurate, the oxycodone detection time for blood tests is shorter. Generally, oxycodone can only be detected in blood for about 24 hours after the last dose. Plasma levels may also be higher in the elderly and people with renal or liver impairment.
Your body breaks down oxycodone hydrochloride into noroxycodone, oxymorphone, and noroxymorphone. It is then excreted by the kidneys into the urine. OxyContin can be detected by screening tests used in employment, forensic, and medical settings. OxyContin can be detected by a urine test for up to four days after the last dose. However, standard drug screenings often do not test for this drug, so additional tests may be used to detect the presence of OxyContin.
The detection window by blood is much shorter and the test is more costly and invasive. For these reasons, blood tests are not used to screen for the presence of OxyContin as frequently as urine tests. However, these tests can detect the substance in the body for up to 24 hours.
OxyContin shows up quickly on saliva screening tests, usually within three hours of taking a dose, and its presence can be detected for up to 48 hours after the last dose.
As with other substances, OxyContin can be detected by a hair follicle test for a much longer period of time, up to 90 days. If you take OxyContin by prescription, it will be detected on typical pre-employment or forensic drug tests.
You should disclose that you are taking this drug by prescription when you are required to take such tests. There are a number of different factors that can influence how long OxyContin is detectable in your body.
For unknown reasons, women have higher plasma levels when taking OxyContin. Other factors, such as how long you've been taking your medication, your individual metabolism, alcohol use, and taking other medications, can also play a role in how quickly OxyContin clears from your body. The dosage schedule and how the substance is taken can also have an impact on detection times. The normal detection windows for OxyContin assume that the medication is taken as prescribed, in whole-tablet form, and on the recommended dosage schedule.
However, when misused, OxyContin tablets may be crushed and snorted or injected. Research has found that when crushed and snorted, OxyContin can be detected within five minutes of administration. The drug is also more bioavailable when taken intranasally, which may affect peak blood plasma levels and duration of detectability.
The type of OxyContin tablet that is crushed may also play a role in how quickly the drug begins to take effect and how it affects the body. One study found that crushing and snorting the controlled-release tablets was associated with lower and delayed peak blood plasma levels. The misuse of prescription opioids such as OxyContin can also result in significant health consequences.
When taken in large doses, these drugs can have serious side effects and can even be fatal. There are a few different steps you can take if you want to speed up how quickly OxyContin is eliminated from your body. The most important is to stop taking the drug, but you should always talk to your doctor before taking this step.
OxyContin can lead to physical dependence, so suddenly stopping your medication can result in withdrawal symptoms. Your doctor may slowly taper you off your medication in order to minimize these symptoms. Once you have safely stopped taking OxyContin, you may be able to slightly increase the drug's metabolism and elimination by making sure that you stay well-hydrated, following a healthy diet, and getting regular physical activity. OxyContin works by altering the way the brain and nervous system respond to pain.
But it also has significant effects on depressing breathing and the cough reflex. An overdose can result in death. To avoid a potentially fatal overdose, you must always take the pill whole and never cut, crush, chew, or inject OxyContin as it's specifically formulated for extended not immediate release into the body. You should also stick to your prescribed dosing schedule to avoid taking too much. Never take two pills together because you missed a dose and never take more than one pill in 12 hours.
The following are some of the symptoms of an OxyContin overdose:. If you suspect someone has taken too much OxyContin and is showing symptoms of overdose, call immediately.
