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