warfarin in the hospital, but wondered, was this the best treatment for me? i spoke to my doctor and she told me about eliquis. eliquis treats dvt and pe blood clots and reduces the risk of them happening again. not only does eliquis treat dvt and pe blood clots. but eliquis also had significantly less major bleeding than knowing eliquis had both... ...turned around my thinking. don't stop eliquis unless you doctor tells you to. eliquis can cause serious, and in rare cases, fatal bleeding. don't take eliquis if you have an artificial heart valve or abnormal bleeding. if you had a spinal injection while on eliquis call your doctor right away if you have tingling, numbness, or muscle weakness. while taking eliquis, you may bruise more easily... and it may take longer than usual for bleeding to stop. seek immediate medical care for sudden signs of bleeding, like unusual bruising. tell your doctor about all planned medical or dental procedures. eliquis treats dvt & pe blood clots. plus had less major bleeding. both made switching to eliquis right for me. ask your doctor if it's right for you. a leading consumer testing publication recently tested the top laundry detergents. the
