Does Methadone Show Up On A Drug Test?
Yes, methadone can show up on a drug test, but not all drug tests are designed to detect it.
Standard drug panels, such as a five-panel test, typically screen for commonly abused substances like marijuana, cocaine, amphetamines, opiates, and PCP, but they do not specifically test for methadone. However, extended drug panels or specialized tests, such as a 10-panel drug test, may include methadone as one of the detectable substances.
Methadone does not metabolize in the same way as other opioids, so it requires specific testing to identify its presence. Most laboratories utilize urine, blood, or hair follicle tests to detect methadone and its metabolites.

Types of Opioids Detectable in Drug Tests
Drug tests can detect a range of opioids, depending on their scope. Common opioids tested include:
Unlike some opioids that show up on standard tests, methadone requires a specific assay to ensure accurate detection.
Why Is Methadone Drug Testing Done?
Testing for methadone is often conducted for:
- Monitoring Recovery Programs: Methadone is used in medication-assisted treatment (MAT) programs, and regular testing ensures adherence to prescribed treatment plans.
- Safety in the Workplace: Certain industries, particularly those involving heavy machinery may test for methadone to ensure an employee’s ability to perform safely.
- Legal and Court-Mandated Testing: Individuals under probation or parole, or those involved in custody disputes, may be tested for methadone to confirm compliance with medical or legal requirements.
Will My Employer Drug Test for Methadone?
Employers generally do not test for methadone in standard workplace drug screenings unless specifically required for the role. For example, transportation, healthcare, and law enforcement industries might implement more comprehensive testing protocols that include methadone.
If you are prescribed methadone, informing your employer ahead of testing may help avoid confusion. Providing a valid prescription ensures that a positive methadone result is not treated as a violation of workplace policies.
Side Effects of Methadone Use
Methadone is effective for pain relief and opioid withdrawal management but can cause side effects. These include:
- Drowsiness
- Nausea
- Constipation
- Dizziness
- Sweating
- Respiratory depression (in higher doses)
If misused or combined with other substances, methadone use can lead to serious health risks, including overdose.
What Drug Tests Are Used to Test For Methadone?
Methadone can be identified through various drug testing methods, including:
- Urine Tests: The most common method, detecting methadone metabolites up to 10 days after use.
- Blood Tests: Used less frequently, detecting methadone within 24–36 hours of use.
- Hair Follicle Tests: Detects methadone use over a longer timeframe, up to 90 days.
Specialized testing is often required to specifically identify methadone, as standard panels may not include it.
