Methadone detoxification is a process which should be overseen by substance abuse professionals within a drug rehab center who realize 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 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 strict supervision at a drug rehab facility which has practical experience in handling this type of detox, and where the individual can receive additional recovery services to handle all addiction issues.
