Let's take a minute to talk about your medication. This is warfarin, and you should take your dose as directed by your doctor. Warfarin prevents and treats blood clots. This is important, because blood clots can cause a stroke, heart attack, and other serious conditions. Your doctor will order a blood test, called an 'INR,' regularly. This shows if the amount of medicine in your body is effective and safe. To keep your INR steady, you should eat a balanced and consistent diet. Specifically, eat the same amount of leafy, green vegetables, from week to week. This includes broccoli, spinach, cabbage, and lettuce, to name a few. Many people take warfarin without problems, but, side effects could occur, like bleeding. So, avoid activities with a risk of injury or falling. Let your doctor know right away if you have unusual bleeding, pink or brown urine, or bowel movements that look like black tar. If concerns about bleeding, or other side effects, make you want to stop taking this medicine, please, talk to your doctor or pharmacist. Tell your doctor and pharmacist all of the medicines you take, and check with them before beginning any new ones, especially aspirin or pain relievers. Women should let their doctor know right away if menstrual bleeding is heavier than normal. Also, notify your doctor immediately if you think you may be pregnant. For best results, continue taking warfarin, because it is helping protect you from problems blood clots can cause.
