Methadone detoxification is a course of action which must be supervised by drug addiction professionals within a drug rehabilitation facility who recognize how difficult and challenging methadone detox can be. Methadone detoxification 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 ease 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 person can receive additional treatment services to handle all addiction issues.
