Methadone detoxification is a process which should be supervised by substance abuse professionals within a drug rehabilitation facility who recognize how difficult and challenging methadone detoxification can be. Methadone detox 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 ease 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 handling this type of detox, and where the individual can receive further treatment services to handle all addiction issues.
