How Long Does Methadone Stay in the Body System?

Oct. 09, 2021

Methadone is a drug that is sometimes used to treat opioid dependence or pain. In the United States, the most common use of methadone is in medication-assisted treatment (MAT) programmes for drug addiction. It is fairly safe if used properly, however, people who abuse methadone may be concerned about passing an eddp drug test.


What is methadone?

Methadone is an opioid that helps treat pain and reduce opioid and heroin withdrawal symptoms. As an anaesthetic, the drug works by reducing the nervous system's response to pain.

Methadone helps with opioid recovery treatment because it effectively blocks the high levels produced by addictive drugs such as heroin, hydrocodone and morphine. On the other hand, some drug users get high by squeezing and snorting or injecting methadone. These individuals may also become addicted to the drug and suffer methadone withdrawal until the drug is eliminated from the system.


What determines length of stay?

Age, weight and gender

Metabolism plays an important role in how quickly the drug leaves your system. Younger people, people of a healthy weight and men tend to take drugs more quickly. Therefore, people who are older, overweight or female may take longer to eliminate methadone from their system.

Dosing schedule

How often and how much a person uses a drug affects how long it stays in the system. For example, someone who takes a high dose of methadone every day for four years in a row will take longer to remove it from their system than someone who only takes a low dose of methadone for a week.

Kidneys and liver

The liver and kidneys work hand in hand to eliminate substances from the body. Therefore, people with poor kidney or liver function may take longer to process methadone and get it out of their system.

Ultimately, there is no fixed answer to how long methadone stays in your system. There are too many factors at play and each person is different.



How long does it stay?

There are four different types of drug tests that can be used to detect methadone in your system. While urine tests are the most common, others include blood, hair follicle and saliva tests. To know more details, you can come to visit WELLBIOSCIENCE.

Urinalysis 

The urine test is the most widely used type of drug test. It can be detected in the urine between 1 hour after initial consumption and 2 weeks after the last dose.

Blood tests 

Blood tests are rarely used as they are considered invasive as far as drug testing is concerned. However, it can be detected in your blood between 30 minutes after consumption and 4 days after your last use.

Hair follicle test

Hair tests have the longest detection window of any drug test. Methadone may be detected in their hair follicles within a few months of taking the drug.

Saliva tests

Saliva tests are rarely used as they have a very short detection window. Methadone can only be detected in your saliva within three or four days of your last use.
