Methadone detoxification is a process which should be supervised by substance abuse professionals within a drug rehabilitation center who recognize how challenging and difficult methadone detox can be. Methadone detoxification is regarded to be far more serious 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 ease symptoms. This is why methadone detoxification must only be done under close supervision at a drug rehab center which has experience in dealing with this type of detoxification, and where the person can receive additional treatment services to address all addiction issues.
