When you are taking anticoagulants, you need to be careful about foods and other medications that may interact with them. Be sure to do the following:

  • Check with your doctor before starting or stopping any other medications, including prescriptions, over-the-counter medications, or supplements.
  • If you are taking anticoagulant medications, do not take aspirin, medications that contain aspirin, or pain relievers known as nonsteroidal anti-inflammatory drugs (NSAIDs) (ibuprofen, Advil, or Aleve). You may take acetaminophen (Tylenol).
  • If you are taking Coumadin, be very consistent about the amount of foods containing vitamin K that you eat. Ask your doctor or nurse for more information.
  • Tell all your healthcare providers, including your dentist, that you're taking anticoagulants. They need to know this before prescribing anything else.
