Oxycodone may be prescribed following an injury, trauma, or major surgery.
It may also be prescribed to treat other types of severe pain, like cancer pain. Oxycodone is derived from the poppy plant. It binds to the mu opioid receptor and blocks the feeling of pain. Since oxycodone works in the pleasure centers of the brain, it has a high potential for abuse and addiction. For this reason, oxycodone is classified as a federal controlled substance C-II. Abruptly stopping the medication can lead to withdrawal symptoms. The amount of oxycodone needed for analgesia pain relief varies widely between people.
Usually, a doctor will start you on a low dose and then increase the dose slowly until your pain is well controlled. People who have taken an opioid medication before may need to take a higher dose in order to experience pain relief. Oxycodone is taken by mouth oral and should be taken with food.
You should start feeling the effects of oxycodone in just 20 to 30 minutes. Oxycodone reaches peak concentrations in the bloodstream in roughly one to two hours following ingestion. Extended- and controlled-release formulations can take three to four hours to reach peak concentration in the bloodstream.
Over time, you may build up a tolerance to oxycodone. This means it may take longer to feel the pain relief or the relief may not feel as strong. When this happens, your doctor may want to increase your dose or switch you to a different type of pain medication.
One way to find out how long a drug will last in your body is to measure its half-life. The half-life is the time it takes for half of the drug to be eliminated from the body.
Immediate-release formulations of oxycodone have average half-life of 3. In other words, it takes 3. It takes several half-lives to fully eliminate a drug. Since everyone metabolizes medications differently, the half-life will vary from person to person. For most people, oxycodone will fully clear the blood within 24 hours, but it can still be detected in the saliva, urine, or hair for longer than that. Controlled or extended-release formulations last longer, so they are usually taken every 12 hours.
A of factors can influence the time it takes for oxycodone to clear the body. These include:. The blood concentrations of oxycodone have been shown to be 15 percent higher in the elderly over age 65 compared to younger adults. It may take longer for elderly people to clear oxycodone from their system. According to the package insert for OxyContin, oxycodone concentration for healthy female subjects was up to 25 percent higher than in males. The same was seen in studies for Xtampza ER. The reason for this is unclear. The average half-life of oxycodone increases by 2.
This means it will take longer to clear oxycodone from the body. One study found that the average half-life of oxycodone increases by one hour in people with kidney problems. If you take oxycodone regularly, it can accumulate in fatty tissues in your body.
The effects of oxycodone are increased if you consume alcohol. Not only will it take longer to clear oxycodone from your body, but it can also lead to dangerous side effects, including a potentially fatal overdose. Drugs that inhibit CYP3A4 make it more difficult for your body to break down oxycodone.
Taking oxycodone with the following medications could result in serious problems, including respiratory depression:. Withdrawal symptoms occur when the body has become dependent on a drug. Dependence is different from addiction. In drug dependence, the body has become used to the presence of a drug, so if you stop taking that drug suddenly, you will experience predictable symptoms known as a withdrawal symptoms.
Your doctor may reduce your dosage gradually over time to prevent withdrawal. This is called tapering. If you do experience withdrawal symptoms, they can be classified as mild, moderate, or severe. Everyone experiences withdrawal differently, but in general symptoms begin to improve within 72 hours and decrease ificantly within a week.
Your doctor can help you manage your symptoms. The pain relief effect of immediate-release oxycodone will wear off within four to six hours, but the drug may still be detected in the saliva and urine for up to four days hours and in the hair for 90 days after the last dose.
There are also a of factors that could alter the time it takes for oxycodone to clear the body, including:. Never take more than your prescribed dose of oxycodone, even if you feel that the medicine is not working. Opioids such as oxycodone have been associated with serious health issues, including addiction and overdose. Inmore than 20, people died from opioid prescription-related overdoses in the United States, according to the American Society of Addiction Medicine.
