what do a nascar® driver... a comedian... and a professional golfer have in common? we talked to our doctors about treatment with xarelto®. xarelto® is proven to treat and help reduce the risk of dvt and pe blood clots. xarelto® has also been 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. 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 ea sily and it may take longer for bleeding to stop.
