Methadone detoxification is a process which must be supervised by substance abuse professionals within a drug rehabilitation facility who realize how challenging and difficult methadone detoxification can be. Methadone detox is regarded to be far more serious in terms of symptoms and duration than even heroin detox, and individuals 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 detoxification should only be done under close supervision at a drug rehabilitation program which has experience in dealing with this type of detox, and where the individual can receive further rehabilitation services to deal with all addiction issues.
