Warfarin Sodium, tablet

Indications and Usage, quoted from the label by Upsher-Smith Laboratories, LLC (ANDA040416). Cross-references to other label sections are left out.

JANTOVEN ®is indicated for:

  • Prophylaxis and treatment of venous thrombosis and its extension, pulmonary embolism (PE).
  • Prophylaxis and treatment of thromboembolic complications associated with atrial fibrillation (AF) and/or cardiac valve replacement.
  • Reduction in the risk of death, recurrent myocardial infarction (MI), and thromboembolic events such as stroke or systemic embolization after myocardial infarction.

Limitations of Use

Warfarin Sodium has no direct effect on an established thrombus, nor does it reverse ischemic tissue damage. Once a thrombus has occurred, however, the goals of anticoagulant treatment are to prevent further extension of the formed clot and to prevent secondary thromboembolic complications that may result in serious and possibly fatal sequelae.
