Check with MD. You should not stop this medication without discussing this with your presscribing doctor. You could suffer harm coming off this anti-coagulant. You are on it for a reason and should stay on it until other arrangements or advise is given. See your prescribing doctor very soon to discuss the pros and cons of this medication and the alternatives.
Talk to your doctor. I am not sure which commercial you are referring to. If you are concerned about side effects such as heart burn talk to your doctor about alternative options. If you have any bleeding call your doctor right away.
