Methadone detoxification is a process which should be supervised by drug addiction professionals within a drug rehab center who realize how challenging and difficult methadone detox can be. Methadone detoxification is regarded to be far more severe 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 close supervision at a drug rehab program which has practical experience in dealing with this type of detox, and where the person can receive additional treatment services to deal with all addiction issues.
