Recommended Dose: The recommended dose of Apixaban for most patients is 5 mg taken orally twice daily.

Dosage Adjustments: The recommended dose of Apixaban is 2.5 mg twice daily in patients with any 2 of the following characteristics: age ≥80 years, body weight ≤60 kg, serum creatinine ≥1.5mg/dl.

CYP3A4 and P-gp inhibitors: When Apixaban is coadministered with drugs that are strong dual inhibitors of cytochrome P450 3A4 (CYP3A4) and P-glycoprotein (P-gp) (e.g. ketoconazole, itraconazole, ritonavir, clarithromycin) the recommended dose is 2.5 mg twice daily.

Missed Dose: If a dose of Apixaban is not taken at the scheduled time, the dose should be taken as soon as possible on the same day and twice-daily administration should be resumed. The dose should not be doubled to make up for a missed dose.

Discontinuation for Surgery and Other Interventions: Apixaban should be discontinued at least 48 hours prior to elective surgery or invasive procedures with a moderate or high risk of unacceptable or clinically significant bleeding. Apixaban should be discontinued at least 24 hours prior to elective surgery or invasive procedures with a low risk of bleeding or where the bleeding would be non-critical in location and easily controlled.

Switching from or to Apixaban: Switching from warfarin to Apixaban: Warfarin should be discontinued and Apixaban started when the international normalized ratio (INR) is below 2.0.

Switching from Apixaban to warfarin: Apixaban affects INR, so that INR measurements during co-administration with warfarin may not be useful for determining the appropriate dose of warfarin. If continuous anticoagulation is necessary, discontinue Apixaban and begin both a parenteral anticoagulant and warfarin at the time the next dose of Apixaban would have been taken, discontinuing the parenteral anticoagulant when INR reaches an acceptable range.

Switching between Apixaban and anticoagulants other than warfarin: Discontinue one being taken and begin the other at the next scheduled dose.

Apixaban can cause a skin rash or severe allergic reaction.

There is no antidote to Apixaban. Overdose of Apixaban increases the risk of bleeding. Activated charcoal may be useful in the management of Apixaban overdose.

Apixaban acts by inhibiting coagulation, and thus prevents development of blood clots. As a result of FXa inhibition, apixaban prolongs clotting tests such as prothrombin time (PT), INR, and activated partial thromboplastin time (aPTT). Changes observed in these clotting tests at the expected therapeutic dose, however, are small, subject to a high degree of variability, and not useful in monitoring the anticoagulation effect of apixaban.

Increased Risk of Stroke with Discontinuation of Apixaban Discontinuing Apixaban in the absence of adequate alternative anticoagulation increases the risk of thrombotic events. An increased rate of stroke was observed during the transition from Apixaban to warfarin in clinical trials in patients with nonvalvular atrial fibrillation. If Apixaban must be discontinued for a reason other than pathological bleeding, consider coverage with another anticoagulant.
