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