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