and help reduce the risk of dvt and pe blood clots. xarelto is also proven to reduce the risk of stroke in people with afib, 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. you know, taking warfarin, i had to deal with that blood testing routine. i couldn't have a healthy salad whenever i wanted. i found another way. 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.
