Methadone detoxification is a process which must be overseen by substance abuse professionals within a drug rehabilitation program who understand how challenging and difficult methadone detox can be. Methadone detox is regarded to be far more serious in terms of symptoms and duration than even heroin detox, and users frequently revert back to methadone to ease withdrawal symptoms or, worse yet, turn to heroin or prescription opioids to relieve symptoms. This is why methadone detoxification should only be done under strict supervision at a drug rehab facility which has practical experience in handling this type of detox, and where the person can receive additional treatment services to deal with all addiction issues.
