Methadone detoxification is a course of action which should be supervised by addiction professionals within a drug rehab center who realize how challenging and difficult methadone detox can be. Methadone detox is regarded to be far more severe in terms of symptoms and duration than even heroin detox, and users typically revert back to methadone to relieve withdrawal symptoms or, worse yet, turn to heroin or prescription opioids to relieve symptoms. This is why methadone detox must only be done under close supervision at a drug rehab center which has experience in handling this type of detoxification, and where the individual can receive additional rehabilitation services to deal with all addiction issues.
