Warfarin and Coumadin precautions

Five things you need to know when taking anticoagulants

Anticoagulants like Coumadin or Jantoven are prescribed to prevent the formation of blood clots.

People taking anticoagulants like Coumadin or Jantoven need to stay in close contact with their healthcare providers.

Many things factor into an individual’s international normalized ratio or INR, which is a measurement of the time it takes for a person’s blood to clot. A patient’s INR must be closely monitored when taking warfarin, also known as Coumadin or Jantoven, so it’s important to stay in close contact with your healthcare provider to avoid dangers associated with taking anticoagulant meds.

5 important warfarin and Coumadin precautions you should take:

  1. Call your healthcare provider if you get sick (including diarrhea, nausea or vomiting).
  2. Call your healthcare provider if you start or stop taking any medications, including over-the-counter medications and supplements.
  3. Notify your healthcare provider if your diet has changed recently, especially if your consumption of green, leafy vegetables or alcohol has changed.
  4. Get all medications from the same pharmacy to avoid the possibility of harmful drug interactions.
  5. Notify your healthcare provider if you forget to take a dose of your warfarin.
