Methadone detoxification is a process which must be overseen by substance abuse professionals within a drug rehab program who recognize how challenging and difficult methadone detox can be. Methadone detox is known to be far more severe in terms of symptoms and duration than even heroin detox, and individuals typically revert back to methadone to ease withdrawal symptoms or, worse yet, turn to heroin or prescription opioids to alleviate symptoms. This is why methadone detox should only be done under close supervision at a drug rehab facility which has experience in dealing with this type of detoxification, and where the individual can receive further recovery services to deal with all addiction issues.
