FAQs About Deep Vein Thrombosis

If I have mild symptoms of a deep vein thrombosis, can I wait and see if the clot will go away on its own?

No. Not treating a deep vein thrombosis can cause very serious complications. If you think you have the symptoms or are unsure if you have the symptoms, see a doctor right away.

Are there any foods that change the way my medications work?

Yes, foods that contain Vitamin K can change how well warfarin (coumadin) will work. This vitamin is found in green leafy vegetables and in some oils like canola and soybean oil. It is best if you eat a well-balanced healthy diet that doesn't vary. For example, you should not make up for having no vegetables one week by eating extra helpings of vegetables the next week.

I hear that alcohol can thin my blood. Can I drink alcohol while taking anticoagulants?

It is important that you discuss with your doctor what amount of alcohol is safe for you to drink.

Do I need to restrict my activities while I am being treated for a deep vein thrombosis?

You should discuss your activities with your doctor. In general, your activities do not need to be restricted.

Can I take over-the-counter medications while taking anticoagulants (blood thinners)?

Some over-the-counter medications, such as vitamin K in multivitamins, may change the way your medications work. Aspirin can also thin your blood. Taking two medications (even if one is over-the-counter) that thins your blood may increase your risk for excessive bleeding. Always check with your health care team before taking any other medications while taking anticoagulants.

Why do I need to have blood testing?

While you are taking anticoagulants, your doctor will need to carefully monitor your clotting ability. Blood tests will measure how quickly your blood clots or if your blood is clotting too slowly. If your lab tests show that your blood is clotting too slowly or too quickly, your medications may be changed or adjusted.
