Methadone detoxification is a process which must be supervised by addiction professionals within a drug rehabilitation program who understand how challenging and difficult methadone detox can be. Methadone detoxification is regarded to be far more serious in terms of symptoms and duration than even heroin detox, and individuals typically revert back to methadone to ease withdrawal symptoms or, worse yet, turn to heroin or prescription opioids to relieve symptoms. This is why methadone detox must only be done under close supervision at a drug rehab facility which has practical experience in dealing with this type of detox, and where the individual can receive further treatment services to address all addiction issues.
