Warfarin: How to use, Side Effects ,Dosage

What is Warfarin?

Warfarin belongs to a class of drugs called anticoagulants. This medication is used to treat blood clots (such as in deep vein thrombosis-DVT or pulmonary embolus-PE) and/or to prevent new clots from forming in your body.  Beneficial blood clots prevent or stop bleeding, but harmful blood clots can cause a heart attack, stroke, deep vein thrombosis or pulmonary embolism. Because warfarin interferes with the formation of blood clots, it is called an anticoagulant. Preventing harmful blood clots helps to reduce the risk of a stroke or heart attack. Conditions that increase your risk of developing blood clots include a certain type of irregular heart rhythm (atrial fibrillation), heartvalve replacement, recent heart attack, and certain surgeries (such as hip/knee replacement).  Many people refer to anticoagulants as “blood thinners”; however, warfarin does not thin the blood but instead causes the blood to take longer to form a clot.  It helps to keep blood flowing smoothly in your body by decreasing the amount of certain substances (clotting proteins) in your blood.

How to use Warfarin?

Take warfarin as directed.

Take your dose every day at the same time.

If you miss a dose, take it as soon as you can. Do not add it to your next dose. Instead, call your doctor, who may want to adjust your next dose.

If you have an INR/CFX test scheduled in the next few days, call your doctor or clinic to see if you should re-schedule.

Do not stop taking warfarin without talking to your doctor.

Do not take warfarin if you are pregnant, may become pregnant or if you are breastfeeding. Warfarin may be harmful to unborn babies and infants.

Take this medication by mouth with or without food as directed by your doctor or other health care professional, usually once a day. It is very important to take it exactly as directed. Do not increase the dose, take it more frequently, or stop using it unless directed by your doctor.

Use this medication regularly to get the most benefit from it. To help you remember, take it at the same time each day.

It is important to eat a balanced, consistent diet while taking warfarin. Some foods can affect how warfarin works in your body and may affect your treatment and dose. Avoid sudden large increases or decreases in your intake of foods high in vitamin K (such as broccoli, cauliflower, cabbage, brussels sprouts, kale, spinach, and other green leafy vegetables, liver, green tea, certain vitamin supplements).
