not caused by a heart valve problem. but i won't accept giving it less than my best. so if i can go for something better than warfarin, ...i will. eliquis. eliquis... reduced the risk of stroke better than warfarin, plus it had less major bleeding than warfarin... eliquis had both. that really mattered to me. don't stop taking eliquis unless your doctor tells you to, as stopping increases your risk of having a stroke. eliquis can cause serious and in rare cases fatal bleeding. don't take eliquis if you have an artificial heart valve or abnormal bleeding. while taking eliquis, you may bruise more easily and it may take longer than usual for any bleeding to stop. seek immediate medical care for sudden signs of bleeding, like unusual bruising. eliquis may increase your bleeding risk if you take certain medicines. tell your doctor about all planned medical or dental procedures. i accept that i'm not as fast, but i'm still going for my personal best... and for eliquis. reduced risk of stroke... plus less major bleeding. ask your doctor... if eliquis is right for you.
