Methadone detoxification is a process which must be supervised by drug addiction professionals within a drug rehabilitation 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 frequently revert back to methadone to relieve 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 center which has practical experience in handling this type of detox, and where the individual can receive further rehabilitation services to deal with all addiction issues.
