Methadone detoxification is a process which should be overseen by substance abuse professionals within a drug treatment facility who realize 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 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 detox must only be done under close supervision at a drug rehab center which has practical experience in dealing with this type of detox, and where the individual can receive further treatment services to handle all addiction issues.
