stroke. that'd be devastating. i took warfarin for over 15 years until i learned more about once-daily xarelto... a latest generation blood thinner. then i made the switch. xarelto® significantly lowers the risk of stroke in people with afib not caused by a heart valve problem. it has similar effectiveness to warfarin. warfarin interferes with vitamin k and at least six blood clotting factors. xarelto® is selective targeting one critical factor of your body's natural clotting function. 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. 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 conditions, such as kidney, liver or bleeding problems. to help protect yourself from a stroke, ask your doctor about xarelto. there's more to know. xarelto. more breaking news. sky 7 hd is
