Methadone detoxification is a process which should be overseen by substance abuse professionals within a drug rehab center who realize how challenging and difficult methadone detox can be. Methadone detoxification is known to be far more serious in terms of symptoms and duration than even heroin detox, and individuals often revert back to methadone to relieve withdrawal symptoms or, worse yet, turn to heroin or prescription opioids to relieve symptoms. This is why methadone detoxification must only be done under close supervision at a drug rehabilitation program which has experience in dealing with this type of detox, and where the person can receive additional treatment services to deal with all addiction issues.
