COUMADIN
Patient Instruction Sheet
The Do’s and Don’ts
Coumadin® is an oral anticoagulant. It is a medication that will help thin your blood in order to prevent clots from forming in your blood vessels. It is very important to maintain an adequate level of Coumadin® in your blood. If the level of Coumadin® is too low, your blood may clot in your blood vessels. If the level of Coumadin® is too high, bleeding may occur.
DO
- Take Coumadin® at the same time every day or as recommended by your doctor or nurse. It is usually taken in the early evening or at bedtime. You may take it with or without food. If you forgot to take your medication and remember it on the same day, take the dose as soon as you remember.
- Keep your appointments for your blood tests. These blood tests are important to help your doctor adjust the dose of your medication that is best suited to you. You may eat the day of your blood test; you do not need to fast before these tests.
