This case involves a 60-year-old woman who suffered from atrial fibrillation for which her cardiologist had prescribed her Xarelto. She planned to undergo an outpatient colonoscopy procedure after experiencing lower abdominal pain, and the gastroenterologist informed patient that she should stop using Xarelto two days prior to the procedure. This instruction was given to the patient without consulting with her cardiologist. After the colonoscopy procedure was performed, she went back on Xarelto later that night. However, early the next morning she suffered a stroke and was taken to the emergency room. She recovered, but subsequently suffered paralysis on the left side of her body. It is alleged that the patient’s cardiologist should have been consulted which would have promoted him to inform the gastroenterologist that patient should have only been taken off the Xarelto for no more than one day.
