Methadone detoxification is a course of action which must be supervised by substance abuse professionals within a drug rehabilitation facility who understand 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 frequently revert back to methadone to relieve withdrawal symptoms or, worse yet, turn to heroin or prescription opioids to relieve symptoms. This is why methadone detoxification should only be done under close supervision at a drug rehab program which has experience in handling this type of detoxification, and where the person can receive further recovery services to handle all addiction issues.
