Methadone detoxification is a process which must be supervised by substance abuse professionals within a drug rehab center who recognize how difficult and challenging methadone detox can be. Methadone detoxification is known to be far more severe in terms of symptoms and duration than even heroin detox, and users frequently revert back to methadone to ease 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 rehabilitation center which has experience in dealing with this type of detox, and where the person can receive further treatment services to handle all addiction issues.
