Methadone detoxification is a course of action which should be supervised by substance abuse professionals within a drug rehab facility who recognize how challenging and difficult methadone detoxification can be. Methadone detox is known to be far more serious in terms of symptoms and duration than even heroin detox, and users often revert back to methadone to ease withdrawal symptoms or, worse yet, turn to heroin or prescription opioids to alleviate symptoms. This is why methadone detox must only be done under strict supervision at a drug rehab program which has practical experience in handling this type of detoxification, and where the person can receive additional treatment services to address all addiction issues.
