...including this little girl. and what if this happened again? i was given warfarin in the hospital, but wondered, was this the best treatment for me? so i asked my doctor. and he recommended eliquis. eliquis treats dvt and pe blood clots and reduces the risk of them happening again. yes, eliquis treats dvt and pe blood clots. eliquis also had significantly less major bleeding than the standard treatment. both made me turn around my thinking. don't stop eliquis unless your 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. eliquis may increase your bleeding risk if you take certain medicines. tell your doctor about all planned ures. eliquis treats dvt and pe blood clots. plus had less major bleeding. both made eliquis the right treatment for me. ask your doctor if switching to eliquis is right for you. finally tonight, two oscar-winning actresses playing two hollywood actresses whose real-life feud is legendary. >> are you threatening me?
