Methadone detoxification is a process which must be overseen by substance abuse professionals within a drug rehab center who recognize how challenging and difficult methadone detox can be. Methadone detox is regarded to be far more severe in terms of symptoms and duration than even heroin detox, and individuals frequently revert back to methadone to ease withdrawal symptoms or, worse yet, turn to heroin or prescription opioids to alleviate symptoms. This is why methadone detoxification must only be done under close supervision at a drug rehab facility which has practical experience in handling this type of detox, and where the person can receive further treatment services to handle all addiction issues.
