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 detoxification is known to be far more severe in terms of symptoms and duration than even heroin detox, and individuals 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 strict supervision at a drug rehab program which has experience in dealing with this type of detoxification, and where the person can receive further treatment services to handle all addiction issues.
