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