When you’re at risk for blood clots, Coumadin can be the most powerful line of defense in your doctor’s arsenal. It can also come with equally powerful side effects. If you’ve been prescribed this medication, also called warfarin, it’s important to know what symptoms indicate an urgent need for medical attention.

Potentially Serious Side Effects of Coumadin

Coumadin is a potentially life-saving drug for those at risk for blood clots, because it actively inhibits clotting. Making the body less effective at clotting blood means you’re also at risk for very serious bleeding events if you are cut or otherwise injured. Other serious side effects, which require immediate medical attention include:

  • Black or bloody stool
  • Severe headache or stomach pain
  • Red or brown urine
  • Severe bleeding, including abnormally heavy menstrual bleeding
  • Changes in vision
  • Weakness or dizziness
  • Coughing up blood
  • Vomiting blood, or vomit resembling coffee grounds
  • Joint pain, discomfort or swelling after an injury

Less serious side effects can occur, like bleeding gums after you brush your teeth, bleeding between menstrual periods, vomiting, diarrhea, and fever. These symptoms and similar ones should be reported to your doctor at your next appointment but are not a medical emergency.
