Are there any risks in taking Coumadin?

Taking Coumadin may cause some people to have internal bleeding. In some cases, this bleeding can become severe and even fatal if not treated in time. The risk for internal bleeding is greatest in people who have certain medical conditions or use some other medications. Tell your pharmacist about all major illnesses you have and any other medications you take, including vitamin supplements and medicinal herbs. Tell your doctor immediately if you have any of the following symptoms while taking Coumadin:
  • pain, swelling or any unexplained discomfort
  • bleeding from a cut that does not stop in the usual amount of time
  • nosebleeds, bleeding gums or any unusual bleeding
  • coughing up or vomiting blood or material that resembles coffee grounds
  • bruising
  • increased menstrual flow or vaginal bleeding
  • changes in urine color, especially if it turns pink, red or dark brown
  • black, tar-like bowel movements
  • headaches, dizziness or weakness
