geico. fifteen minutes could save you fifteen percent or more on car insurance. my dad has aor afib.brillation, he has the most common kind... ...it's not caused by a heart valve problem. dad, it says your afib puts you at 5 times greater risk of a stroke. that's why i take my warfarin every day. but it looks like maybe we should ask your doctor about pradaxa. in a clinical trial, pradaxa® (dabigatran etexilate mesylate)... ...was proven superior to warfarin at reducing the risk of stroke. and unlike warfarin, with no regular blood tests or dietary restrictions. hey thanks for calling my doctor. sure. pradaxa is not for people with artificial heart valves. don't stop taking pradaxa without talking to your doctor. stopping increases your risk of stroke. ask your doctor if you need to stop pradaxa before surgery or a medical or dental procedure. pradaxa can cause serious, sometimes fatal, bleeding. don't take pradaxa if you have abnormal bleeding or have had a heart valve replaced. seek immediate medical care for unexpected signs of bleeding, like unusual bruising. pradaxa may increase your bleeding risk if you're 75 or older, have a bleeding condition or stomach ulcer,
