Jantoven Side Effects Center

Jantoven (warfarin sodium) is used to prevent heart attacks, strokes, and blood clots in veins and arteries. It is an anticoagulant (blood thinner). This medication is available in generic form. Common side effects include nausea, loss of appetite, or stomach/abdominal pain.

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.
