Standard therapy for thrombosis commonly consists of intravenous heparin followed by warfarin. Treatment of a pregnant patient with a history of recurrent fetal loss is controversial but generally includes subcutaneous heparin and aspirin.

Warfarin (Coumadin)

Interferes with hepatic synthesis of vitamin K–dependent coagulation factors. Long-term warfarin is DOC for APS in patients with recurrent thrombotic events. Titrated dose suggested to maintain INR in therapeutic range (see above).

Enoxaparin (Lovenox)

LMWH. Most experience; other LMWH preparations available.


Used in inpatient settings as continuous infusion during conversion to warfarin therapy until a therapeutic INR is achieved. May be administered SC as substitute for warfarin during attempted pregnancy or for temporary anticoagulation during warfarin loading in outpatient setting.

Aspirin (Anacin 81, Ascriptin, Bayer Aspirin)

Although not proven effective when used alone, most clinicians use aspirin with SC heparin in pregnant patients with APS. Begin aspirin as soon as conception is attempted.
