Coumadin (warfarin) is a prescription medication that prevents the formation of harmful blood clots.
In most cases, blood clots are beneficial and prevent or stop bleeding. However, when blood clots form in your blood vessels, they may lead to serious cardiac conditions such as:
Coumadin decreases your body’s ability to create blood clots by blocking the formation of vitamin K-dependent blood clotting factors. When prescribed Coumadin/warfarin, you may have to take the medication for the rest of your life.
You may refer to Coumadin as a blood-thinner. However, the anticoagulant doesn’t thin your blood. It slows down your blood’s ability to form a blood clot, which may cause excessive bleeding if you have a cut or wound.
The goal of Coumadin/warfarin treatment is to decrease your blood’s clotting tendency, not prevent blood clotting completely. You need Coumadin/warfarin checks to monitor your blood clotting abilities.
Getting too much or too little Coumadin or warfarin may lead to medication complications such as excessive bleeding or the formation of harmful blood clots.
Your weekly Coumadin/warfarin checks at the Heart Care Center of Northwest Houston monitor your blood clotting abilities to make sure you’re getting the right dose.
Your Coumadin/warfarin check is a blood test. Your provider draws a sample of blood from your arm and measures your:
PT (pro time test) measures how long it takes your blood to clot.
Your PT is reported as an INR, which is the standardized way of expressing the PT value. The INR ensures that your PT results are consistent no matter what lab you use to conduct your Coumadin/warfarin checks.
The Heart Care Center of Northwest Houston determines the frequency of your Coumadin/warfarin checks. Some patients only need checks once a month, while others need checks twice a week.
