Methadone detoxification is a process which must be supervised by substance abuse professionals within a drug rehab program who recognize how difficult and challenging methadone detoxification can be. Methadone detox is regarded to be far more severe in terms of symptoms and duration than even heroin detox, and users typically revert back to methadone to alleviate withdrawal symptoms or, worse yet, turn to heroin or prescription opioids to relieve symptoms. This is why methadone detox should only be done under close supervision at a drug rehab center which has experience in handling this type of detox, and where the individual can receive additional treatment services to handle all addiction issues.
