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