Methadone detoxification is a course of action which should be supervised by drug addiction professionals within a drug rehab program who understand 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 often 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 should only be done under strict supervision at a drug rehab facility which has experience in dealing with this type of detox, and where the person can receive further recovery services to address all addiction issues.
