Methadone detoxification is a process which must be supervised by addiction professionals within a drug rehabilitation center who recognize how difficult and challenging methadone detoxification can be. Methadone detoxification 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 ease symptoms. This is why methadone detox should only be done under close supervision at a drug rehabilitation center which has experience in dealing with this type of detoxification, and where the person can receive further rehabilitation services to deal with all addiction issues.
