Methadone detoxification is a process which should be supervised by addiction professionals within a drug rehab program who understand how challenging and difficult methadone detoxification can be. Methadone detox is known to be far more severe in terms of symptoms and duration than even heroin detox, and individuals 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 detox must only be done under strict supervision at a drug rehab facility which has practical experience in dealing with this type of detoxification, and where the person can receive additional recovery services to deal with all addiction issues.
