Methadone detoxification is a process which must be overseen by substance abuse professionals within a drug rehabilitation facility who realize how challenging and difficult methadone detox can be. Methadone detoxification is regarded 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 close supervision at a drug rehabilitation program which has practical experience in handling this type of detox, and where the person can receive additional treatment services to handle all addiction issues.
