Precautions While Using This Medicine:

Tell all medical doctors, dentists,  and pharmacists  you go  to that  you are taking this medicine. 

Check with  your doctor right away  if you notice any unusual  bleeding or bruising. 

Check with  your health care professional before  you start or stop taking any other medicine, or change the amount you  are taking. This includes any nonprescription (over-the-counter OTC) medicine, even aspirin or acetaminophen. Many medicines change the way this medicine affects your body. You may not be able  to take the other medicine,  or the dose of your anticoagulant may need to be changed. 

It is important that you carry identification stating that you  are using this medicine.  If you have any questions about what kind of identification to carry, check with  your health care professional.

While  you are taking this medicine, it is very important  that you avoid sports and activities that may cause you to be injured. Report to your doctor any falls, blows to the body or head, or other injuries, since serious internal bleeding may occur without your knowing about it. 

Be careful to avoid cutting yourself. This includes  taking special care in brushing your teeth and in shaving. Use a soft toothbrush and floss gently. Also, it is best to use an electric shaver rather than a blade. 

Drinking too much alcohol may change the way this anticoagulant affects  your body. You should not drink regularly on a daily basis or take more than 1 or 2 drinks at any time. If you have any questions  about this, check with your doctor. 

The foods that you eat may also affect  the way this medicine affects your body. Eat a normal, balanced diet  while you are taking this medicine.  Do not go on a reducing diet, make other changes in  your eating habits, start taking vitamins, or begin using other nutrition supplements unless you have first checked with your health care professional.

Also, check  with your doctor  if you are unable to eat for several days or  if you have continuing stomach upset, diarrhea, or fever. These precautions are important because the effects of the anticoagulant depend on the amount of vitamin K in your body. Therefore,  it is best to have the same amount of vitamin K in  your body every day. Some multiple vitamins and some nutrition supplements contain vitamin K. Vitamin K is also present in green, leafy vegetables (such as broccoli, cabbage, collard greens, kale, lettuce, and spinach) and some vegetable oils. It is especially important that you do  not make large changes in  the amounts of these foods that you eat every day while you are taking an anticoagulant. 

Be careful if the weather is very hot for several days. This could increase the effects  of the medicine. 

After you stop taking this medicine,  your body will need time to recover before your  blood clotting ability returns to normal. Your health care professional can tell  you how long this will take depending on which anticoagulant you were taking. Use the same caution during this period of time as you did while you were taking the anticoagulant.
