Methadone detoxification is a process which should be overseen by addiction professionals within a drug rehab facility who recognize how difficult and challenging methadone detox can be. Methadone detox is regarded to be far more serious in terms of symptoms and duration than even heroin detox, and users frequently 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 should only be done under close supervision at a drug rehab facility which has experience in handling this type of detoxification, and where the individual can receive additional rehabilitation services to address all addiction issues.
