Important Safety Information

WARNING: SPINAL/EPIDURAL HEMATOMAS

Epidural or spinal hematomas may occur in patients who are anticoagulated with low molecular weight heparins (LMWH), heparinoids,
or fondaparinux sodium and are receiving neuraxial anesthesia or undergoing spinal puncture.

These hematomas may result in long-term or permanent paralysis. Consider these risks when scheduling patients for spinal procedures. Factors that can increase the risk of developing epidural or spinal hematomas in these patients include:

  • use of indwelling epidural catheters
  • concomitant use of other drugs that affect hemostasis, such as nonsteroidal anti-inflammatory drugs (NSAIDs), platelet inhibitors,
    or other anticoagulants
  • a history of traumatic or repeated epidural or spinal puncture
  • a history of spinal deformity or spinal surgery

Monitor patients frequently for signs and symptoms of neurologic impairment. If neurologic compromise is noted, urgent treatment is necessary. Consider the benefit and risks before neuraxial intervention in patients anticoagulated or to be anticoagulated for thromboprophylaxis.

ARIXTRA indications for the prophylaxis of venous thromboembolism (VTE) after abdominal surgery in high-risk patients*

ARIXTRA helped protect most patients from venous thromboembolism (VTE) following abdominal surgery [12]

Rate of VTE at Day 10 in Abdominal Surgery

*Surgery was high risk if patients were >60 years of age, or >40 and <60 with 1 or more additional risk factors for VTE or who were undergoing abdominal surgery with general anesthesia expected to last >45 minutes. [12]

... With a low incidence of major bleeding [12]

97.2% of patients who received ARIXTRA following abdominal surgery were free from major bleeding when the dose was administered 6 hours after surgery. [12]

Incidence of Major Bleeding

Major bleeding was defined as fatal bleeding, bleeding that was retroperitoneal, intracranial, intraspinal, or involved in any other critical organ, bleeding leading to reoperation or intervention, or a BI >2.0. BI=number of units of transfused packed RBC or whole blood + difference between prebleeding and postbleeding hemoglobin in g/dL.

Study summary for VTE prophylaxis after abdominal surgery [12,13]

PEGASUS was a randomized, double-blind, double-dummy trial of abdominal surgery patients at risk for thromboembolic complications. Patients received ARIXTRA 2.5 mg once-daily or dalteparin 5,000 IU SC once-daily, with one 2,500 IU SC preoperative injection and one 2,500 IU SC first postoperative injection.

INDICATIONS AND USAGE
Prophylaxis of Deep Vein Thrombosis
ARIXTRA is indicated for the prophylaxis of deep vein thrombosis (DVT), which may lead to pulmonary embolism (PE) in patients undergoing:

  • hip fracture surgery, including extended prophylaxis;
  • hip replacement surgery;
  • knee replacement surgery;
  • abdominal surgery who are at risk for thromboembolic complications.

Treatment of Acute Deep Vein Thrombosis
ARIXTRA is indicated for the treatment of acute deep vein thrombosis when administered in conjunction with warfarin sodium.

Treatment of Acute Pulmonary Embolism
ARIXTRA is indicated for the treatment of acute pulmonary embolism when administered in conjunction with warfarin sodium when initial therapy is administered in the hospital.

CONTRAINDICATIONS
ARIXTRA is contraindicated in the following conditions:

  • Severe renal impairment (creatinine clearance <30 mL/min) in prophylaxis or treatment of venous thromboembolism.
  • Active major bleeding.
  • Bacterial endocarditis.
  • Thrombocytopenia associated with a positive in vitro test for anti-platelet antibody in the presence of fondaparinux sodium.
  • Body weight <50 kg (venous thromboembolism prophylaxis only).

WARNINGS AND PRECAUTIONS

  • Use with caution in patients who have conditions or who are taking concomitant medications that increase risk of hemorrhage.
  • Bleeding risk is increased in renal impairment and in patients with low body weight <50 kg.
  • Thrombocytopenia can occur with administration of ARIXTRA.
  • Periodic routine complete blood counts (including platelet counts), serum creatinine level, and stool occult blood tests are recommended.
  • The packaging (needle guard) contains dry natural rubber and may cause allergic reactions in latex sensitive individuals.
