take certain medicines. xarelto can cause serious and in rare cases, fatal bleeding. get help right away for unexpected bleeding, unusual bruising, or tingling. if you have had spinal anesthesia while on xarelto , watch for back pain or any nerve or muscle related signs or symptoms. do not take xarelto if you have an artificial heart valve or abnormal bleeding. tell your doctor before all planned medical or dental procedures. before starting xarelto , tell your doctor about any kidney, liver, or bleeding problems. xarelto is the number one prescribed blood thinner in its class. well that calls for a round of kevin nealons. make mine an arnold palmer. same here. with xarelto there is no regular blood monitoring and no known dietary restrictions. treatment with xarelto was the right move for us.
