Methadone has its own drug test but may show up as an opioid on a general drug test. Methadone hydrochloride can also be detected on a drug test for longer than most other drugs. The detection window is based on what’s being tested:

- Blood: A blood test might show positive results for methadone for up to5–130 hoursafter its last use. The variable detection window with blood tests is one reason they’re not the preferred drug testing method.

Is Methadone Hydrochloride Safe?
When methadone is used as part of a treatment plan and is taken as prescribed, it’s considered a safe medication. However, methadone works similarly to other opioids, so there is a potential for misuse and addiction. A physician has to prescribe methadone, and it must be provided under a specific program that’s carefully supervised.
After some time, people may be able to take methadone on their own within certain programs or states. At first, however, patients can only receive methadone in a clinical setting. Methadone can only be dispensed through anopioid treatment program (OTP)certified by the Substance Abuse and Mental Health Services Administration (SAMHSA). Some people may require methadone treatment for a year or more, sometimes indefinitely.

Using methadone without a prescription is illegal. Professionals who are licensed to prescribe methadone have to undergo specific training and receive certifications through SAMHSA’s Division of Pharmacologic Therapies.

When someone uses methadone hydrochloride (whether it’s prescribed for pain, addiction, or they’re using it illegally), it affects opioid receptors in the brain. Methadone is aCNS depressant.
Methadone exerts its action by being an opioid agonist, which means it activates opioid receptors. The effects of methadone areslowerthan other opioids, however. When someone uses it as prescribed, it works more slowly than other opiates, and while it can provide pain relief, it doesn’t create euphoria.
At high doses, individuals who use methadone can experience euphoria. The physical and psychological effects of methadone are similar to other opioids. For example, methadone hydrochloridecan causedrowsiness, dry mouth and gastrointestinal symptoms.
