Liver Dose Adjustments
Mild liver impairment (Child-Pugh A): No adjustment recommended
Moderate liver impairment (Child-Pugh B): These patients may have intrinsic coagulation abnormalities and there is limited experience with apixaban in these patients; therefore, data is not available.
Severe liver impairment (Child-Pugh C): Not recommended
Dose Adjustments
Coadministration with strong dual CYP450 3A4 and P-gp inhibitors:
- Patients receiving over 2.5 mg orally 2 times a day: Reduce dose by 50%

Precautions
The US FDA requires a Risk Evaluation and Mitigation Strategy (REMS) for apixaban. It includes a communication plan. For additional information: www.fda.gov/REMS
US BOXED WARNINGS:
PREMATURE DISCONTINUATION INCREASES THE RISK OF THROMBOTIC EVENTS:
- Premature discontinuation of any anticoagulant increases the risk of thrombotic events.
- To reduce this risk, consider coverage with another anticoagulant if apixaban is discontinued for a reason other than pathological bleeding or completion of therapy.
SPINAL/EPIDURAL HEMATOMA:
- Epidural or spinal hematomas may occur in patients treated with apixaban who 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.
Safety and efficacy have not been established in patients younger than 18 years.
Consult WARNINGS section for additional precautions.
Dialysis
Hemodialysis:
Nonvalvular atrial fibrillation patients with end stage renal disease: 5 mg orally 2 times a day
Reduce dose to 2.5 mg orally 2 times a day if patient is 80 years or older OR body weight is 60 kg or less.
Deep vein thrombosis prophylaxis after hip or knee replacement: No adjustment required.
Deep vein thrombosis (DVT) and pulmonary embolism (PE) treatment: No adjustment required.
Recurrent DVT and PE risk reduction: No adjustment required.
Other Comments
Administration advice:
- May take with or without food.
- Missed dose: Take as soon as possible on the same day then resume twice daily administration. Do not double up to make up for a missed dose.
- Stop medication 48 hours prior to surgery or invasive procedures with moderate to high risk of unacceptable or clinically significant bleeding.
- Stop medication 24 hours prior to surgery or invasive procedures with low bleeding risk or where bleeding would be in a non-critical location and easily controlled.
- Bridging anticoagulation is generally not required.
- Restart after surgery/procedure as soon as adequate hemostasis has been established.
- Patients unable to swallow whole tablets: The manufacturer product information should be consulted.
