It is used for the prophylaxis and/or treatment of venous thrombosis, and for pulmonary embolism. Prophylaxis and/or treatment of thromboembolic complications associated with atrial fibrillation and/or cardiac valve replacement. It is also indicated for reducing the risk of death from recurrent myocardial infarction and from thromboembolic events such as stroke or systemic embolization.

Pregnancy and breastfeeding
Pregnancy:
Oral anticoagulants derived from coumarin, such as warfarin, cross the placenta and are not recommended for use during pregnancy. Congenital malformations and other adverse effects on fetal development have been described in children born to mothers who took this medication during the first trimester. Oral anticoagulants cross the placenta with a risk of fetal or placental bleeding when administered weeks before delivery. In cases where anticoagulant therapy is essential, the use of heparin is recommended, especially during the first trimester, as it does not cross the placenta.
Tell your doctor as soon as you suspect you may be pregnant or if you wish to become pregnant. Consult your doctor or pharmacist before taking any medication.
Breastfeeding:
Warfarin is not detected in breast milk, so no adverse effects are expected in the breastfed infant.
