Methadone is a prescription medication commonly used to manage pain and as part of medication-assisted treatment (MAT) programs for individuals with opioid dependence, such as those recovering from heroin or prescription painkillers. While it’s often taken just once a day, methadone can stay in your system for a much longer period, depending on several factors. Understanding how long methadone remains in your body is crucial if you are prescribed this medication.
How Long Does Methadone Last?
The duration of methadone’s effects depends on its purpose. When prescribed for pain management, methadone typically provides relief for four to eight hours. However, when used in MAT programs for opioid use disorder, the drug’s effects last significantly longer, typically 24 to 48 hours.
Methadone’s Half-Life
A drug’s half-life refers to how long it takes for the body to eliminate half of the medication. Methadone’s half-life is highly variable, ranging from 8 to 59 hours or even longer, depending on individual factors. Because it takes about five half-lives for a drug to be completely eliminated from the body, methadone can linger in your system for an extended period.
With prolonged use, methadone metabolism changes, potentially causing the drug to accumulate in the body and extend its presence. This means that even after stopping methadone, it can take days or weeks for the substance and its metabolites to fully clear.

Detection of Methadone in Drug Tests
Methadone and its metabolite, EDDP (2-Ethylidene-1,5-dimethyl-3,3-diphenylpyrrolidine), can be detected in various drug tests:
- Urine: Methadone and EDDP can be detected for up to 14 days after the last dose.
- Hair: A 1.5-inch sample of hair can reveal methadone use for up to 90 days.
- Blood: Methadone remains detectable in the bloodstream for up to 55 hours after the last dose.
- Saliva: While rarely used due to unreliability, methadone can sometimes be detected in saliva for up to two days.
Does Methadone Appear on a Drug Test?
Methadone is commonly included in drug testing, especially in cases involving legal, employment, or medical compliance requirements. On drug tests, methadone is often abbreviated as MTD. These tests are used to monitor adherence to prescribed methadone regimens or to detect misuse.
False Positives for Methadone
Although rare, false positives can occur. Non-opioid medications are usually responsible for such results, including:
- Verapamil (used for blood pressure)
- Diphenhydramine (antihistamine)
- Doxylamine (antihistamine)
- Quetiapine (antipsychotic)
If a drug test erroneously shows methadone use, confirmatory testing can clarify the results and rule out false positives.
Factors That Influence How Long Methadone Stays in Your System
Several variables can affect how long methadone remains detectable in your body:
- Frequency of Use
Methadone accumulates with repeated use. Regular doses can cause the drug to build up, prolonging the time it takes to leave the body. - Age and Health
Younger individuals with better overall health often process and eliminate drugs like methadone more quickly than older or less healthy individuals. - Dosage
Higher doses of methadone take longer to be metabolized and excreted compared to smaller doses. - Medical Conditions
Certain conditions, such as pregnancy, can alter methadone metabolism. For instance, pregnant women in their second and third trimesters may eliminate methadone more quickly. - Drug Interactions
Some medications can interact with methadone, either speeding up or slowing down its metabolism and affecting how long it stays in the system.
Quitting Methadone: Overcoming Addiction
For individuals struggling with methadone dependence, the thought of stopping the medication can feel overwhelming. However, recovery is possible with the right support system and treatment plan.
