Methadone detoxification is a process which must be supervised by substance abuse professionals within a drug rehabilitation center who recognize how difficult and challenging methadone detox can be. Methadone detox is known to be far more serious in terms of symptoms and duration than even heroin detox, and individuals frequently revert back to methadone to relieve withdrawal symptoms or, worse yet, turn to heroin or prescription opioids to relieve symptoms. This is why methadone detox should only be done under strict supervision at a drug rehab center which has practical experience in dealing with this type of detox, and where the individual can receive additional recovery services to deal with all addiction issues.
