Methadone detoxification is a process which must be overseen by substance abuse professionals within a drug rehab program who realize how challenging and difficult methadone detox can be. Methadone detox is known 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 alleviate symptoms. This is why methadone detox should only be done under strict supervision at a drug rehabilitation facility which has practical experience in handling this type of detoxification, and where the person can receive additional rehabilitation services to deal with all addiction issues.
