not caused by a heart valve problem. for people with afib currently well managed on warfarin, there is limited information on how xarelto® and warfarin compare in reducing the risk of stroke. i tried warfarin before, but the blood testing routine and dietary restrictions had me off my game. not this time. not with xarelto®. i'll have another arnold palmer. make mine a kevin nealon. really, brian? 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® has been prescribed more than
