blood testing routine. i couldn't have a healthy salad whenever i wanted. i found another way. yeah, treatment with xarelto®. hey, safety first. like all blood thinners, don't stop taking xarelto® without talking to your doctor, as this may increase your risk of a blood clot or stroke. while taking, you may bruise more easily and it may take longer for bleeding to stop. xarelto® may increase your risk of bleeding if you 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. ask your doctor about xarelto®.
