Methadone detoxification is a process which must be supervised by addiction professionals within a drug rehabilitation facility who understand how challenging and difficult methadone detox 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 alleviate withdrawal symptoms or, worse yet, turn to heroin or prescription opioids to relieve symptoms. This is why methadone detoxification must only be done under close supervision at a drug rehab program which has experience in handling this type of detoxification, and where the individual can receive further rehabilitation services to deal with all addiction issues.
