Methadone is an opioid agonist commonly used in medication-assisted treatment (MAT) to alleviate opioid withdrawal symptoms and reduce cravings by drug detoxification.
According to 2015 statistics, approximately 350,000 patients receive methadone treatment for Opioid Use Disorder (OUD) each day in the United States alone.
Understanding the duration of methadone in the body is of significant importance for individuals undergoing opioid addiction treatment programs.
SAMHSA mandates that individuals undergoing methadone treatment for opioid addiction must actively engage in a drug treatment program. Certified opioid treatment programs are the sole authorized sources for obtaining methadone.
Healthcare professionals can administer and supervise the administration of methadone based on each patient’s requirements and must be taken exactly as directed. Methadone can be habit-forming, which increases the risk of misuse or substance abuse.
As an opioid agonist, Methadone binds to opioid receptors in the brain, producing similar effects to other opioids while minimizing the euphoric high.
Methadone is absorbed through oral administration, with its bioavailability varying depending on several factors such as individual metabolism and the presence of other substances in the body. The liver metabolizes methadone, resulting in the formation of various metabolites. The elimination of methadone from the body primarily occurs through renal excretion and urinary elimination, with the half-life being a crucial indicator of methadone’s duration in the system.
The half-life of methadone is variable, ranging from 8 to 59 hours, depending on various factors such as individual metabolism and dose of methadone. The human body typically takes five half-lives to eliminate a drug, which means methadone can stay in your system for approximately 13 days at the latest.
Methadone’s half-life refers to the time it takes for half of the drug to be eliminated from the body. On average, methadone lasts between 24 and 36 hours in the human body. However, it’s important to note that this duration can vary significantly among individuals.
As methadone is used for opioid addiction treatment, its half-life also differs for opioid-tolerant and opioid-native people. For opioid-tolerant patients, methadone has a half-life of approximately 24 hours. Meanwhile, methadone’s half-life for opioid-naive patients is longer, at approximately 55 hours.
The actual amount of time methadone stays in your system may vary depending on the factors listed below.
The rate at which your body metabolizes methadone can vary depending on a number of factors, such as age. People with faster metabolisms will typically clear methadone from their systems more quickly than people with slower metabolisms.
The higher the dosage of methadone you take, the longer it will stay in your system. This is because it takes longer for your body to metabolize a larger amount of the drug. Tapering off methadone gradually under medical supervision can further affect the drug’s elimination.
The longer you have been taking methadone, the longer it will stay in your system. This is because methadone can build up in your body over time.
Some medications can interact with methadone and prolong its half-life. For example, cimetidine, an over-the-counter medication used to treat heartburn, can increase the half-life of methadone by up to 50%.
People with higher body weights tend to clear methadone from their systems more slowly than people with lower body weights.
If you have liver problems, it may take longer for your body to metabolize methadone.
The elimination of methadone from your body usually takes around two weeks; however, the detection of residual amounts can vary depending on the type of drug test employed.
Methadone drug tests may be required by employers, addiction treatment programs, athletic organizations, and law enforcement authorities. It is important to note that traces of methadone can be detected for an extended period beyond the initial two-week timeframe.
Various methods are used to detect methadone in biological samples. Urine tests are commonly used for methadone screening due to their effectiveness and wider detection period.
Urine tests are preferred due to their noninvasive nature, ease of administration, relatively low cost, and extended period of detection. The detection time for methadone in urine ranges from one hour to two weeks after ingestion.
Saliva tests provide a convenient and noninvasive alternative for methadone testing. Traces of methadone can be detected in saliva as early as 30 minutes after ingestion and can remain detectable for a few days following the last use.
Hair tests are particularly useful for assessing long-term methadone as traces of the drug accumulate in the hair over time. It may take up to a couple of weeks for methadone to appear in the hair of someone who has recently started taking it. Methadone can be detected in hair for several months after the last use.
Blood tests can detect methadone within 30 minutes of use and remain effective for a few days. While blood tests are highly accurate, they are costly, invasive, and have a relatively short detection window. Therefore, they are not commonly utilized for methadone testing purposes.
While methadone is an effective medication for opioid addiction treatment, it is not without risks. Some individuals may develop a dependence on methadone itself, leading to methadone addiction. Recognizing the signs of addiction and seeking help is crucial for recovery and overall well-being.
