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