Methadone detoxification is a process which must be overseen by substance abuse professionals within a drug rehab facility who understand how challenging and difficult methadone detox can be. Methadone detox is regarded to be far more serious in terms of symptoms and duration than even heroin detox, and individuals typically 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 should only be done under strict supervision at a drug rehab center which has experience in handling this type of detoxification, and where the person can receive additional recovery services to handle all addiction issues.
