Methadone detoxification is a process which must be supervised by addiction professionals within a drug rehabilitation center who understand how challenging and difficult methadone detoxification can be. Methadone detoxification is known to be far more severe 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 ease symptoms. This is why methadone detoxification should only be done under close supervision at a drug rehab facility which has practical experience in dealing with this type of detoxification, and where the individual can receive further rehabilitation services to deal with all addiction issues.
