My wife was found to have a blood clot in the lungs, as per cat scan. She is in the hospital with heparin sodium I V. We were asked to decide what medication to be given, Xarelto or Coumadin? She has hiatal hERNIA, gastritis, Acid Reflux, IBS-C, Extruding Disk, Hernieted Disk, Anxiety, High Blood Pressure. She has so many medicines already. Thank you for whatever advise you may provide.
