Methadone detoxification is a process which should be supervised by substance abuse professionals within a drug rehabilitation program who understand how challenging and difficult methadone detox can be. Methadone detoxification is known to be far more severe in terms of symptoms and duration than even heroin detox, and individuals typically 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 person can receive further treatment services to handle all addiction issues.
