Especially now that i live with a higher risk of stroke due to afib, a type of irregular heartbeat, not caused by a heart valve problem. I was taking warfarin, but wondered if i kept digging, could i come up with something better. My doctor told me about eliquis. For three Important Reasons. One, in a clinical trial, eliquis was proven to reduce the risk of stroke better than warfarin. Two, eliquis had less major bleeding than warfarin. And three, unlike warfarin, theres no routine blood testing. Dont 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. Dont 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. Those three Important Reasons are why eliquis is a better find for me. Ask your doctor today if eliquis is right for you. Know that chasing performance and fewer choices in retirement.
