Methadone detoxification is a course of action which must be overseen by substance abuse professionals within a drug rehab facility who understand how difficult and challenging methadone detox can be. Methadone detoxification is regarded to be far more serious 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 ease symptoms. This is why methadone detox should only be done under close supervision at a drug rehab facility which has experience in dealing with this type of detoxification, and where the individual can receive additional recovery services to deal with all addiction issues.
