Answer

Admitted patients may be treated with a LMWH, fondaparinux, or unfractionated heparin (UFH). Warfarin 5 mg PO daily is initiated and overlapped for about 5 days until the international normalized ratio (INR) is therapeutic >2 for at least 24 hours.

For admitted patients treated with UFH, the activated partial thromboplastin time (aPTT) or heparin activity level must be monitored every 6 hours while the patient is taking intravenous (IV) heparin until the dose is stabilized in the therapeutic range. Patients treated with LMWH or fondaparinux do not require monitoring of the aPTT.

Platelets should be monitored. Heparin or LMWH should be discontinued if the platelet count falls below 75,000. Fondaparinux is not associated with hepatin-induced thrombocytopenia (HIT).
