- Get regular blood tests to ensure that you are taking the right amount of medication.
- Eat a balanced diet.
- Do not suddenly change your intake of vitamin K–rich foods, such as broccoli, brussels sprouts, cabbage, asparagus, lettuce, spinach, and some vegetable juices. It is most important to maintain a consistent level of vitamin K foods in your diet. Vitamin K can interfere with the action of warfarin, making it more likely that your blood will clot.
- Avoid excessive use of alcohol. If you drink, do so only in moderation. Alcohol may increase the effect of warfarin.
- Don't use tobacco of any kind.
- Talk to your doctor before taking any vitamins or supplements. Do not take ginkgo biloba or garlic while using warfarin.
- Avoid activities that have a high risk for injury, such as skiing, football, or other contact sports. If you are taking warfarin, an injury could result in excessive bleeding.
- Wear a seat belt anytime you are traveling in a car.
