Coumadin Therapy


Taking coumadin is a very important part of your treatment.

Your doctor, nurse and pharmacist will do all they can to ensure coumadin works well for you, but you must take charge of your coumadin therapy.

What you need to do

  • Take coumadin as prescribed for you. Know what common problems might arise and how to respond.

  • Report for all scheduled clinic and laboratory appointments. 

How to take coumadin

  • Make sure you have the correct tablets. Check the color and number printed on the tablet.

  • Take coumadin at the same time each day. A good time to take it is with your evening meal.

  • If you forget to take coumadin, do not take another tablet to catch up.

  • Talk with your doctor, nurse or pharmacist about any concerns you may have while you are taking coumadin.

  • Be sure to have your blood work done on time. 

Negative signs to watch for

  • Blood in the urine or stools.

  • Bleeding cuts that do not heal.

  • Bleeding from the nose.

  • Unexplained bleeding or bruising under the skin.
If you experience any bleeding that does not stop quickly, immediately call the clinic nurse or your doctor.

About Vitamin K

Vitamin K blocks the action of coumadin. Some foods such as green vegetables have a lot of vitamin K in them, so you need to be careful about what you eat or your coumadin level may need to be adjusted.
If you have any questions or concerns, talk to your doctor or a nurse at the Anticoagulation Clinic.
