Methadone detoxification is a course of action which must be overseen by substance abuse professionals within a drug rehab program who recognize 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 users often revert back to methadone to alleviate withdrawal symptoms or, worse yet, turn to heroin or prescription opioids to alleviate symptoms. This is why methadone detoxification should 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 individual can receive further recovery services to handle all addiction issues.
