What Is OxyContin?

OxyContin, is a sustained, controlled-release formulation of oxycodone. It’s a painkiller available by prescription only. OxyContin is legitimately prescribed for relief of moderate to severe pain resulting from injuries, arthritis, and cancer. Individuals abuse OxyContin for the euphoric effect it produces, an effect similar to that associated with heroin use.

The main ingredient in OxyContin, oxycodone, is a pure opioid whose main purpose is pain relief. OxyContin is prescribed in daily doses of 10-80mg, and is to be taken orally as a tablet. It is available as a 10mg, 20mg, 40mg, or 80mg tablet which varies in color and size according to dosage. The tablets are imprinted with the letters OC on one side and the number of milligrams on the opposite side.

Ways People Take OxyContin

People who abuse OxyContin cut, break, chew, crush, or dissolve OxyContin. But this type of use leads to rapid immediate release of oxycodone in the body and can lead to overdose or death. The potency of OxyContin is about equal to morphine.

Peak Levels of OxyContin

The peak level of a drug is the highest level of a medicine in the body. Peak levels are compared with trough levels, which are the lowest concentration of the medicine in the body. These two indicators help doctors monitor drug use and adjust prescriptions accordingly.

OxyContin tablets achieve maximal blood level peak concentrations at about three hours after dosing, compared with 1-1.5 hours for immediate release oral oxycodone. Dose proportionality has been established for the 10mg, 15mg, 20mg, 30mg, 40mg, 60mg and 80mg tablet strengths for both peak plasma concentrations and extent of absorption.

Half Life Of OxyContin

A medicine’s half-life is how long it takes for half of the dose to be eliminated from the bloodstream. In medical terms, the half-life of a drug is the time it takes for the plasma concentration of a drug to reach half of its original concentration.

The mean apparent half-life of OxyContin tablets is 6.5 hours and steady state is achieved in about one day. As a comparison, oxycodone has an elimination half-life of approximately three hours and is metabolized in the liver.From this comparison, we can see how OxyContin is truly an extended release version of oxycodone, as it take the body nearly twice as long to eliminate half of the drug from the system.

OxyContin Drug Testing & Detection Windows

Typically, drug screens for OxyContin are urine based. Initial screening uses an immunoassay method to identify the presence of oxycodone. Then, a second confirmatory test is required unless a positive result has been expected or drug use is disclosed. Confirmatory drug tests additional testing methods to verify a presumptive positive result.The recommended cutoff level for oxycodone is 100ng/ml, below the standard opioid assay cutoff level of 300ng/ml.

Blood Tests For OxyContin

In the blood, oxycodone can be detected within 15 to 20 minutes from the time of ingestion. The concentration reaches its peak within 1 hour but remains detectable at a constant concentration for up to 1 day.

During a blood test, the blood sample is obtained by inserting a needle into a vein in the arm and drawing blood into a tube.This test will identify the level of drug that is present in the blood. Oxycodone is detected for a shorter amount of time in blood compared to urine.

Hair Tests For OxyContin

Oxycodone can also be detected in hair follicles around 1 month, sometimes up to 3 months depending on the length of the hair sample.Hair tests have an extended detection window of approximately 1 month per half inch of hair. Thus, a 1.5 inch section of hair captures a 90-day window of drug use.

Hair is tested and usually collected from the crown of the head, although hair may also be collected from other locations, such as the chest or underarm.The average detection window may vary based on an individual’s hair growth rate and other factors and detection is quite expensive and reliable for routine drug testing.

Oral Fluid Test For OxyContin

Oxycodone appears in oral fluid within 15-30 minutes after oral administration. During an oral drug test, saliva is collected in an absorbent pad or swab placed between the lower cheek and gums for a few minutes. If your saliva is to be collected for testing, you typically should not put anything in your mouth for the 10 minutes prior to the collection of the sample.

Urine Tests For OxyContin

Urine is the most frequently tested sample for opioids like Oxy. Oxycodone is initially detected within 2 hours of drug administration. The oxycodone contained in OxyContin can be detected in urine for 1-3 days.Oxymorphone, a metabolite of oxycodone, is also present in the urine of users.

During a test, urine is collected in a clean container. It cannot be used to determine when or how much drug was consumed.

False Positives

False-positive screens are the result of cross-reactivity to antibodies found in drug tests. This occurs because specific medications directly bind to the antibody due. Other cases of false positive occur because of inadvertent ingestion of oxycodone. Medications that commonly produce a false positive for OxyContin include:

  • Diphenhydramine
  • Doxylamine
  • Quetiapine
  • Quinolone antibiotics
  • Rifampin
  • Verapamil

Poppy seeds can readily result in a positive finding in standard urine testing.A careful history for medications or food that can induce a false-positive result should be performed and, if present, chromatography–mass spectroscopy testing should be used to distinguish between the presence of true opiates and false-positive results.

In situations in which a patient is taking a prescribed opiate, like oxycodone, as well as an illicit opiate, physicians must be especially careful when interpreting test results. Opiate abuse by opiate-treated chronic pain patients is common and can complicate interpretation of opiate testing.

What If I Test Positive?

If you had a test to detect OxyContin, and the result is positive, you may be able to oppose it as mistaken or wrong. The truth is that drug tests can sometimes be unreliable and give a false positive, as we explain above, or labs can make mistakes.

The main goal of drug testing is not punishment. It isprevention of addiction and/or early detection of people who have started to use drugs. The goal is to identify the problem early so that you can get the help you need to become drug-free.

You do need to know that in cases of severe addiction and signs of domestic abuse due to substance use, a doctor can call in social services. In fact, they must report you to social services if you have custody of children. You may be facing time in jail, or state or federal prison, OR lose your privileges in a probation setting.

However, if you failed the test, you can do some things that can help you to prove that you are innocent. Here are some of the rights that you have when you’ve tested positive for OxyContin in your system.

Failed a WORKPLACE drug test?

  • Your employer might allow you to retake the test.
  • You can require the laboratory to test your sample again.
  • Your employer can require an additional test with only one hour notice.
  • You can ask for a hair drug tests to be done.

Failed a CLINICAL drug test?

  • Talk with your practitioner about other prescription medicines you use.
  • Talk with your doctors about over-the-counter medications you use.
  • If a laboratory confirmatory test it’s not already a part of the testing process, you can ask for it.

Failed a STUDENT drug test…

  • Your parents or legal guardians will be informed, but the school may allow you to retake the drug test.
  • Your parents and school can require the laboratory to retest your sample or collect a new sample in a short window of time.
  • You and your parents can ask for a hair sample to be sent to the lab for testing.

Home Tests

Home drug tests for OxyContin typically indicate if oxycodone or its metabolite, oxymorphone is present in urine. This testing is fairly sensitive to the presence of oxycodone in the urine. This means that if drugs are present, you will usually get a preliminary positive test result. After a positive test, it is very important to send the urine sample to the laboratory to confirm a positive at home result because certain medicines can affect the results of home tests. Laboratory tests are the most reliable way to confirm drugs of abuse.

Home drug tests are usually qualitative tests. You’ll be able find out if OxyContin is present in the urine, but not how much is present.An OxyContin home drug test usually contains:

  • A sample collection cup.
  • A test strip, a test card, a test cassette, or other method for testing.
  • An instruction leaflet or booklet.

Accurate testing is done in two steps:

STEP 1: You do a quick at home test. It is very important that the person doing the test reads and understands the instructions first, before even collecting the sample, because with most test kits, the result must be visually read within a certain number of minutes after the test is started.

STEP 2: If the test suggests that drugs may be present, you send the sample to a laboratory for additional testing. Take no serious actions until you get the laboratory’s result. As you may know now, many factors may cause a false positive result in the home test.

If you have questions about using these tests, or the results that you are getting, you should contact your healthcare provider.

OxyContin And Addiction Liability

People who take OxyContin to get high are most likely to become addicted to OxyContin. Anyone who takes OxyContin in ways other than prescribed – cut, broken, chewed, crushed, or dissolved – or people who take OxyContin without a prescription is at risk of becoming addicted to the drug.

Under the Controlled Substances Act, OxyContin is classified as a Schedule II drug. This means that there is a medical use for OxyContin, but that it has a high potential for abuse that may lead to a severe psychological or physical dependence.

  1. took 80mg of oxy in doses up till 9pm saturday… had blood test on monday about 2:30pm.. will it still show up… i hoping it does

  2. I have to take a hair follicle test for a job but I’ve been taking 15 mg of oxy a day for like a month for back pain is there any way to rid my hair of the drug?

  3. I have used Oxycontin for many years. First 80 mg, when my spinal pain & arthritis, & other severe pain, then when it was at a level, I thought I could handle, using a lower dose, I started taking 40mg 2x per day. In all that time, I have never taken an extra pill, nor ever felt high…, just able to function like a normal perso, with some pain, but manageable. There were 3 days, that my Dr. Said I could take 3 tabs, 1 every 8 hours, when I broke my leg. Now I am finding myself, after 20 years being a model patient, 5 days with no prescription…, it was written, but when trying to fill, it stated waiting for prior approval… I am in such extreme pain I don’t know what to do??? I was told by my pharmacist, that I could pay cash for it, but it is $700. If I pay this amount, will insurance, reimburse this amount, once prior authorization is reinstated??? Signed, Helpless & in pain Thank you for listening… Any suggestions, greatly appreciated… I need my life back… 😞💝😌

  4. Oxycontin has such bad PR. It is a life saving drug for people that truly are living in chronic pain. It’s a shame people & politicians don’t educate themselves. If people want to abuse it and end up dying from an overdose, that is fine. Cleaning the population. I am sick and tired of the Govt punishing us because dumbasses choose to abuse it. Those of you that depend on it to function, make your voice heard with your elected officials or don’t open your mouth when they take it away. Your silence now is telling them it is okay.

  5. I’ve been on 60mg extended for 3xdly and 30 mg ir 2 pills 3-4 daily. My chronic pain seems endless. 4 back surgeries, neck fusion, 6 shoulder operations, parathyroid surgery, endless sciatica pain and weakness in my left leg and low back pain whenever I even try to move the trash. A bullet would be cheaper. I continually talk with doctor and psychologist about addiction and they say dependence. After 8 years I’m constantly concerned

  6. Thanks for the info. I am trying to learn all I can so I can have no problems with this drug. I was taking only 2/3rds of what I was prescribed until recently when my pain got alot worse. So I figured I better learn all that I can just to be safe. Thanks very much for your help!

  7. hi I took a oxycotin 20 mg on a mon a week ago, I’m 215lbs only one will it be out of my system a week later,? can it still get detected if it gets sent to a lab a week later?

  8. I have been on opiate pain meds for many years (, prescribed ) Right now my dose is 4 15 mg per day, to taper off what is the best time table, and would Suboxin help, or how does Suboxin help with tapering off the opiates. Thanks

  9. I am taking Oxycontin for about 4 months about 2 30mlg a day sat morining waS my last one it is now monday will it be out of my system n how long till i feel normal

  10. I was just wondering, i have been taking oxycontin for a few yrs, un perscribed. I dont take it to be high, i have deteriorated disc in my back and some bad knees i dont take it every day. Often i will miss a few days.i use between 40-60 mg when is do take it.doctors wo t give me pain meds. I dnt knw why.

An anyo e tell me how i can taper down enuff to where i wo t feel like death or am i in this for life?

    1. Hi Rob. Of course you are not stuck for life. In general, the best way to withdrawal from OxyContin is to have your OxyContin dose tapered over time with the help of a physician. Generally, OxyContin doses are decreased by about 20%-25% from your current dose every week (but you can decrease doses every other week). The slower and more gradual the tapering, the better and safer for you. You can use medications treat OxyContin withdrawal symptoms, such as: antidepressants, clonidine (for regulating blood pressure), insomnia medications, NSAIDs (medications like Advil or ibuprofen can help with aches and pains). Speak with your pharmacist about any additional over-the-counter medications and herbal remedies that can help you lessen withdrawal symptoms.

    1. Hello Ashlee. Well, experts claim that OxyContin can be detected in the urine 1-3 days after its use. However, it all depends on the drug dosage, time of use, frequency, metabolism, etc. I think you should tell your doctor that you took half pill, and the reason why you took it, so s/he will understand.

  11. Just wanted to know how long it will it take my body to feel better again since I went off 120mg I feel so tried and want to sleep alot just need an answer please

    1. Hello Ida. Everything depends on how the drug affects your body. It needs time for your body to adapt the new environment, the environment without OxyContin. Be patient in your recovery, and if you can’t used to it, talk with a doctor to plan you a tapering schedule.

  12. I have taken OxyContin a few times 5 – 6 days ago, and I have taken a home test to prescreen myself for an upcoming job which requires a drug test.

    The results show basically negative but the line is very faint.

    I have been drinking plenty of water and detoxing with organic green juice. Why does the test kit still faintly look positive for OXY?

  13. this is for anyone asking how long it takes oxycodone to leave your body for a urine test. its been answered already just read. 24-72 hours. done. again, 24-72 hours, 1-3 days, 24-72 hours,
    1440-4320 minutes, 24-72 hours, 1-3 days, 1440-4320 minutes, 86400-259200 seconds. one more time… 24-72 hours. it’s everywhere… and here I even created a formula for u.

    d x 200 x 2^-(n/h)

    where d = the dose in milligrams you took, n = hours since your last dose, and h = the biological half-life of said substance. since there is a range with half-life do the math with the minimum and the maximum half-life to give you your range. if you use everyday double the dose to be safe. if you use twice a day triple the dose. if you use three or more times a day quadruple the dose to be safe. your answer is in nanograms per milliliter. even if you do 10 30’s at a time 3 times a day your last dose would be 300mg. quadrupled is 1200mg and when plugged in with a maximum half-life of 5 hours, after 60 hours your level is 58.6 n/ml which passes most of the time.

  14. How long does it stay in your system if you were properly prescribed by dr. And it’s been 2 years???? Because I’m detoxing & wanna be done with this evil drug, it’s day 4!

  15. I took 5 oxy 20 on Saturday i have taken any i a mounth or 2and got to take drug test Tuesday morning pee and mouth swab will I pass

  16. Hi Chris. As stated in the article above, OxyContin can be detected in urine for 1-3 days after the last dose was taken. Best of luck with the job!

  17. how long doaes oxy stay in your system ive been takin like 60mg a day for a month n I have a drug screen n 5 days will I b alright I really need this job

  18. Scotty Smith, when the time comes look into some herbal alternatives. The Kratom Tree indigenous to south east Asia, is the best thing for opiate withdraws. Only nature can truly be your solution to the torture that nature has bestowed upon the dependence to opiates. Any man made or engineered derivatives will poison your body and mind further. So good health and god-speed.

  19. Hello Scotty… I have been addicted to Oxycodone, Oxycontin, Heroin and Methadone and have had to come off of all of them at one time or another. I recently kicked methadone after a 4 month taper process from 80ml/day to 6ml/day and had horrible withdrawl symptoms. But I had found that the more i focused and worried about the withdrawl, the worse it was to go through.

    Basically, dont worry about it. Concentrate on staying healthy and beating the cancer. You will be in such a great state of mind when you beat it, that a tapered withdrawl will be nothing at all to handle.

    Good Wishes,
    Jay

  20. Hello scotty. We wish you a full and healthy body – one that is cancer and pain free! When the time comes to get off OxyContin and oxycodone, you can work out a tapering schedule with your prescribing doctor. Tapering dosages over the course of 4-6 weeks is an effective way of decreasing the intensity and severity of withdrawal symptoms. Additionally, you can ask for more information about medications like clonidine which target specific withdrawal symptoms. Lastly, there are over-the-counter and home remedies like NSAIDs, warm bath/shower and hot pads which can help ease discomfort caused by withdrawal. In the end, withdrawal is an uncomfortable phase…but one that will pass.

    Does this help?

  21. i been on oxycontin 40 mg and oxycodone 10 mg now for 4 years. i have cancer and constantly in severe pain. im scared if and when i do get better if ill be haveing those auful withdraws . and if so what can i do about it. right now if i dont take it i end up back in the er. i no at times i shake really bad. well ty
