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