Methadone detoxification is a process which must be supervised by substance abuse professionals within a drug rehabilitation facility who realize how difficult and challenging 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 frequently revert back to methadone to alleviate withdrawal symptoms or, worse yet, turn to heroin or prescription opioids to alleviate symptoms. This is why methadone detoxification must only be done under close supervision at a drug rehabilitation program which has practical experience in handling this type of detox, and where the individual can receive further recovery services to address all addiction issues.
