Coumadin Tablets

Coumadin® (
 warfarin sodium) is a prescription anticoagulant, often described as a "blood thinner" (although it does not actually thin the blood). The medication is used to prevent and treat blood clots due to various causes. It comes in tablet form and is available in nine different strengths.
 
Coumadin tablets are typically taken once a day. Although it does not matter what time of day you take this medication, it is important that you take it at the same time each day. If you do not take your Coumadin as scheduled, take your missed dose as soon as possible on the same day. However, you should never take two doses on the same day or take a double dose, as an overdose could potentially cause life-threatening problems as the result of dangerous internal bleeding.
 
Just like any medicine, Coumadin can cause side effects, which can be dangerous. The risk of most dangerous side effects can be reduced by careful monitoring. Possible side effects of Coumadin include but are not limited to:
 
  • Bleeding, including dangerous internal bleeding
  • Easy bruising
  • "Purple toe syndrome"
  • Hair loss.
