Methadone detoxification is a course of action which should be supervised by drug addiction professionals within a drug rehab program who realize how challenging and difficult methadone detoxification can be. Methadone detox is known 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 alleviate symptoms. This is why methadone detoxification must only be done under close supervision at a drug rehab program which has experience in dealing with this type of detoxification, and where the individual can receive further recovery services to handle all addiction issues.
