Methadone detoxification is a process which should be overseen by substance abuse professionals within a drug rehabilitation facility who realize 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 often 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 center which has experience in dealing with this type of detox, and where the person can receive further treatment services to address all addiction issues.
