What Is Methadone?
Methadone is a synthetic opioid medication that is used to treat pain and opioid addiction. It is a long-acting medication that works by binding to the same receptors in the brain that opioids such as heroin and fentanyl bind to, but it does not produce the same intense high. Methadone is typically taken orally in the form of a tablet or liquid.
How Long Does Methadone Stay in Your System?
The length of time that methadone stays in your system depends on a variety of factors, including your age, weight, metabolism, and overall health. On average, methadone can be detected in your urine for up to 4-7 days after your last dose. However, it can remain in your system for longer periods of time depending on your individual circumstances.
How Is Methadone Metabolized?
After you take methadone, it is metabolized in your liver and converted into several metabolites, including EDDP and EMDP.

The amount of time it takes for methadone and its metabolites to be cleared from your system depends on a variety of factors, including your metabolism and the dose you took.
