How long does OxyContin last?

OxyContin (main ingredient oxycodone) effects usually occur within 15-30 minutes of taking OxyContin and can last for up to 12 hours. Because OxyContin used for round-the-clock pain relief has been formulated to slowly release a continuous supply of oxycodone to the system, OxyContin shouldn’t be taken more than twice a day. More here on the effects of Oxys, including what happens when you get high on OxyContin, and a section for your questions about OxyContin at the end.

OxyContin effects on the body and brain

How does OxyContin affect the brain and body?  OxyContin is an opioid painkiller that helps manage moderate and severe pain around the clock. Oxycodone, the main ingredient in OxyContin, is a pure opioid agonist analgesic. Oxycodone acts by binding to receptors found on the surfaces of certain cells, mostly in the brain. As oxycodone interacts with specific opioid receptors in the central nervous system both analgesic and euphoric effect occur. The feeling of intense well being that occurs when you take OxyContin is why after long-term use or abuse, OxyContin can become addictive, and why you must have a prescription for OxyContin to use it legally in the U.S.

Because OxyContin depresses the central nervous system, it can cause a variety of side effects, including:

  • drowsiness
  • lightheadedness
  • loss of consciousness
  • difficulty with coordination
  • impaired breathing
  • nausea and vomiting
  • slowed heart rate

OxyContin duration of action

OxyContin generally takes action within 20 minutes, providing quick pain relief, OxyContin’s main ingredient, oxycodone has a short half-life – only about 3.2 hours, so the medication is formulated to slowly release a continuous supply of oxycodone into the blood. While other form of oxycodone only last about 6 hours, OxyContin remains active for 12 hours at a time.

OxyContin time in the body

Traces of oxycodone will remain in the blood for at least a couple of days after the last OxyContin pill, due to the slow release of the drug in the body. In fact, oxycodone can show up on urine screens for around 2 days after the last dose of OxyContin was taken. Hair samples may still retain traces of OxyContin 3 months or more after your last dose.

How long do OxyContin effects last

OxyContin’s effects last 12 hours. How much OxyContin to overdose? It depends on your opiate tolerance.  But to avoid overdose, OxyContin should never be taken more frequently than once every 12 hours.

How long does a OxyContin high last

While OxyContin helps relieve pain around the clock, the high from abusing it won’t last a full 12 hours. If it’s being crushed and snorted, the high won’t last very long – typically only the 6 hours it takes for oxycodone to leave the body. If it’s abused by ingesting the pills, the high will last longer, around 8 hours. However, snorting OxyContin or taking it in large amounts to get high is incredibly dangerous because it’s so easy to overdose on this medication. OxyContin is not safe to take except under a doctor’s direction for a specific medical condition.

OxyContin high effects

One reason that OxyContin is so frequently abused is the euphoric high it can create. Users of OxyContin have reported the following effects:

  • relaxation, stress relief
  • feelings of numbness
  • lightheadedness
  • sense of well-being

Keep in mind that taking OxyContin to get high does carry a number of risks, including addiction, withdrawal symptoms, and overdose. If you have any questions about OxyContin use or abuse, feel free to ask them below.

My girlfriend is addicted to oxycotin and has had multiple nights staying up, puking everywhere, getting angry at me when I try to help or stop her, and can’t stop taking it. I have no idea how she gets them but I’ve done all I know to keep her away from it but she always seems to get it. Is there any ways that I can help her with her addiction or anything? I don’t know what else to do.

Hello Hannah. Look into Narc-Anon and get help and support for yourself. You may need to address enabling behavior, or possible co-dependence. Have you thought about staging an intervention? It sounds like the situation has gotten pretty bad.

Hello, I was wondering how long Oxycontin stay in your system if you need to take a urine test.

10:28 am November 18th, 2014

Hi Keisha. Determining exactly how long oxycodone is detectable in the urine depends on many variables, including which kind drug test is being used. But, 3-4 days after the last dose was administered is a generally safe time-range.

Hello Wanda. Speak with your pharmacist for precise information about extended release medications; you’ll need an expert opinion/input about metabolism in order to understand the medication further.

Hi Neli. What were you taking the OxyContin for? Mention to your doctor that you want proper detox and withdrawal treatment and care after you are out of your medication. You don’t have to suffer and s/he should not be forcing you to go cold turkey.

For the past 4 months I have been taking a single 20mg tablet every 24 hours to help me sleep due to arthritic hip pain. What bothers me is an empty feeling in my upper and lower body, and drowsiness that kicks in after lunch time the day after I take it. If I didn’t use OxyContin one night would the drowsiness disappear as quickly or does it stick around for a few days? Also, is the empty feeling a withdrawal symptom, even though I seem to be taking much less than others who have these problems?
