Methadone detoxification is a process which should be supervised by drug addiction professionals within a drug rehab facility who recognize how challenging and difficult methadone detox can be. Methadone detoxification is regarded 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 alleviate symptoms. This is why methadone detoxification must only be done under strict supervision at a drug rehab facility which has practical experience in dealing with this type of detox, and where the person can receive further rehabilitation services to address all addiction issues.
