Methadone detoxification is a process which should be supervised by substance abuse professionals within a drug rehabilitation facility who recognize 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 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 detox should only be done under strict supervision at a drug rehab program which has practical experience in dealing with this type of detox, and where the person can receive further rehabilitation services to address all addiction issues.
