Jantoven (warfarin sodium) is an anticoagulant (blood thinner) used to prevent heart attacks, strokes, and blood clots in veins and arteries. Jantoven is available in generic form. Common side effects of Jantoven include:

Tell your doctor if you have serious side effects of Jantoven including:

  • pain, swelling, hot or cold feeling, skin changes, or discoloration anywhere on your body;
  • sudden and severe leg or foot pain, foot ulcer, purple toes or fingers;
  • sudden headache, dizziness, or weakness;
  • unusual bleeding, bleeding from wounds or needle injections, any bleeding that will not stop;
  • easy bruising, purple or red pinpoint spots under your skin;
  • blood in your urine, black or bloody stools, coughing up blood or vomit that looks like coffee grounds;

  • urinating less than usual or not at all;
  • numbness or muscle weakness; or
  • any illness with diarrhea, fever, chills, body aches, or flu symptoms.

The dose of Jantoven is individualized, and is based on clinical findings. Jantoven can interact with herbal (botanical) products including: bromelains, coenzyme Q10, danshen, dong quai, garlic, ginkgo biloba, ginseng, or St. John's wort. Jantoven interacts with many other drugs, and these interactions can be dangerous, even fatal. Tell your doctor all prescription and over-the-counter medications and supplements you use. Jantoven is not recommended for use during pregnancy because of serious (possibly fatal) harm to a fetus. Discuss birth control with your doctor. If you become pregnant or think you may be pregnant, tell your doctor. Consult your doctor if you plan to become pregnant. Your doctor may switch the type of medication you use during pregnancy. Very small amounts of this medication may pass into breast milk but it is unlikely to harm a nursing infant. Consult your doctor before breastfeeding.

  • bleeding from wounds or needle injections that will not stop;
  • heavy menstrual periods or abnormal vaginal bleeding;

Clots formed by warfarin may block normal blood flow, which could lead to tissue death or amputation of the affected body part. Get medical help at once if you have:

  • pain, swelling, hot or cold feeling, skin changes, or discoloration anywhere on your body; or
  • sudden and severe leg or foot pain, foot ulcer, purple toes or fingers.
