Methadone detoxification is a process which should be overseen by drug addiction professionals within a drug rehabilitation program who recognize how challenging and difficult methadone detox can be. Methadone detox is known to be far more serious in terms of symptoms and duration than even heroin detox, and users typically revert back to methadone to ease withdrawal symptoms or, worse yet, turn to heroin or prescription opioids to ease symptoms. This is why methadone detoxification 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 person can receive further rehabilitation services to handle all addiction issues.
