Methadone detoxification is a process which must be overseen by substance abuse professionals within a drug rehab facility 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 users frequently revert back to methadone to alleviate withdrawal symptoms or, worse yet, turn to heroin or prescription opioids to relieve symptoms. This is why methadone detox should only be done under close supervision at a drug treatment center which has experience in dealing with this type of detox, and where the person can receive further treatment services to deal with all addiction issues.
