Prothrombin time (PT) is a blood test that measures how long it takes blood to clot, and can be used to check for bleeding problems. PT is also used to check whether medicine to prevent blood clots is working.
True or False: It may take longer than usual for people taking warfarin to stop bleeding if cut or injured.
If you're taking warfarin, it may take longer than usual for you to stop bleeding if you are cut or injured, so you should avoid activities or sports that have a high risk of causing injury. Call your doctor if bleeding is unusual or if you fall and get hurt, especially if you hit your head.
True of False: The best thing to do if you miss a dose of warfarin is to take the dose you missed the next day.
If you miss your dose of warfarin, take the missed dose as soon as you remember it if it is the same day that you were to take the dose. Do not take a double dose the next day to make up for a missed one, and always talk to your doctor if you miss a dose of warfarin.
True or False: People taking warfarin should avoid ALL foods containing Vitamin K.
People taking warfarin should eat a normal, healthy diet with the same amount of foods that contain vitamin K as they did before taking the drug. Be sure to talk to your doctor before you make any changes in your diet or try to gain or lose weight. Do not eat large amounts of leafy, green vegetables or certain vegetable oils, such as soybean or canola, that contain large amounts of vitamin K. Also, avoid juice or products that contain cranberries and ask your doctor about eating licorice while taking warfarin.
True or False: Taking NSAIDs or medications containing aspirin, such as ibuprofen, while taking warfarin can increase your risk of bleeding.
Tell your doctor and pharmacist what prescription and nonprescription medications, vitamins, and nutritional supplements you are taking or plan to take, especially antibiotics; aspirin or aspirin-containing products and other nonsteroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen (Advil, Motrin) and naproxen (Aleve, Naprosyn).
