Patients & Caregivers

Whether you’re helping out a friend or a family member, there are a few important things you should know about the patient’s COUMADIN® (Warfarin Sodium Tablets, USP) therapy.

COUMADIN® is an anticoagulant. Anti means against, and coagulant refers to blood clotting. An anticoagulant helps reduce clots from forming in the blood.

The patient’s PT/INR must be measured regularly

It is important that patients have their blood tested regularly with a test known as an INR (International Normalized Ratio), sometimes referred to as a PT (Protime) test. The PT/INR allows the doctor to monitor the therapeutic effect of COUMADIN® and make dosage adjustments as needed.

Report any problems

If any of the following occur, call the patient’s doctor or nurse immediately:

  • Patient becomes pregnant or plans to become pregnant
  • Fever or illness, including vomiting, diarrhea, or infection
  • Pain, swelling, discomfort, or any other unusual symptoms
  • Prolonged bleeding from cuts or nosebleeds
  • Unusual bleeding from gums when brushing teeth
  • Increased menstrual flow or vaginal bleeding
  • Red or dark brown urine
  • Red or black stools
  • Unusual bruising for unknown reasons
  • Do not allow patient to start, discontinue or change other medicine without doctor’s advice.
  • Always tell other doctors, dentists, pharmacists, or nurses that the patient is on COUMADIN® (Warfarin Sodium Tablets, USP).
  • Patient should keep the same general diet from day to day.
  • Patient should avoid alcohol.
  • If patient forgets to take a tablet, let the doctor know immediately. The patient should take the missed dose as soon as possible on the same day, but should NOT take a double dose of COUMADIN® the next day.
  • Be aware that COUMADIN® and all generic warfarin tablets represent the same medication and should not be taken together as overdosage may result.

  • If you have had a heart attack, COUMADIN may be used to lower the risk of death, another heart attack, stroke, and blood clots moving to other parts of the body.

IMPORTANT SAFETY INFORMATION:

  • The PT/INR test checks to see how fast your blood clots. Your healthcare provider will decide what PT/INR numbers are best for you. Your dose of COUMADIN will be adjusted to keep your PT/INR in a target range for you.
  • Tell your healthcare provider right away if you have any signs or symptoms of bleeding problems such as the following: pain, swelling or discomfort, headache, dizziness, or weakness, unusual bruising, nosebleeds, bleeding of gums, bleeding from cuts that take a long time to stop, menstrual flow or vaginal bleeding that is heavier than normal, pink or brown urine, red or black stools, coughing up blood, or vomiting blood or material that looks like coffee grinds.
