Apixaban Preoperative Discontinuation
Hold apixaban for 1 day (24 hours) before low-to-moderate bleeding risk procedures and 2 days (48 hours) before high bleeding risk procedures in patients with normal renal function. 1, 2
Discontinuation Based on Bleeding Risk
Low-to-Moderate Bleeding Risk Procedures
- Stop apixaban 1 day (24 hours) before surgery, corresponding to 2-3 half-lives and achieving minimal residual anticoagulant effect 1, 2
- Examples include arthroscopy, laparoscopic cholecystectomy, abdominal hernia repair, colonoscopy with biopsy, and coronary angiography 1, 2
- This timing allows for approximately 3-6% residual anticoagulant effect at the time of procedure 3
High Bleeding Risk Procedures
- Stop apixaban 2 days (48 hours) before surgery, corresponding to 4-5 half-lives and achieving minimal residual anticoagulant effect 1, 2
- Examples include cardiac surgery, intracranial/spinal surgery, major abdominal surgery, and surgery in highly vascular organs 1, 3
- This extended interruption ensures minimal anticoagulant activity at the time of the procedure 1
Neuraxial Procedures (Special Consideration)
- Stop apixaban 3 days (72 hours) before spinal or epidural anesthesia, even in patients with normal renal function 4, 2
- This longer discontinuation period is mandatory due to the catastrophic risk of epidural hematoma and associated lower limb paralysis 1, 4
Renal Function Considerations
Renal function assessment is mandatory before determining the discontinuation timeline, as apixaban has 25-27% renal clearance 4, 3
Patients with Moderate Renal Impairment (CrCl 30-50 mL/min)
- Stop apixaban 3 days before low-to-moderate bleeding risk procedures 3
- Stop apixaban 4 days before high bleeding risk procedures 3
- Extended interruption is essential because impaired renal function significantly prolongs apixaban elimination 4, 3
Patients with Severe Renal Impairment (CrCl <30 mL/min)
- Consider 3+ days of preoperative cessation, as these patients can accumulate apixaban and experience catastrophic bleeding 2, 3
FDA-Approved Guidance
The FDA label states: "Apixaban tablets 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" and "at least 24 hours prior to elective surgery or invasive procedures with a low risk of bleeding" 5
Bridging Anticoagulation
Do not use bridging anticoagulation during the interruption period 2, 3
- Bridging with heparin or low molecular weight heparin increases major bleeding risk without reducing stroke or systemic embolism 3
- The rapid offset and rapid onset of action of apixaban obviates the need for heparin bridging 1
Postoperative Resumption
Low Bleeding Risk Surgery
- Resume apixaban at least 24 hours after surgery once adequate hemostasis is established 1, 2
- Full therapeutic dose (5 mg twice daily) can be resumed at this time 2
High Bleeding Risk Surgery
- Resume apixaban 48-72 hours after surgery once adequate hemostasis is established 1, 2
- Consider reduced dose (2.5 mg twice daily) for the first 2-3 days in high thrombotic risk patients before advancing to full therapeutic dosing 2, 3
Critical Pitfalls to Avoid
- Do not use INR or aPTT to guide timing, as apixaban's effect on these tests is inconsistent and unreliable for surgical clearance 4, 2
- Do not resume therapeutic-dose apixaban in the presence of an epidural catheter 2
- Avoid premature resumption after high-risk surgery, as apixaban has rapid onset of action (peak effect 1-3 hours) and can precipitate major bleeding if hemostasis is incomplete 1, 3
- Account for factors affecting drug absorption after major abdominal surgery, such as postoperative bowel dysmotility and acid-suppressive therapy 3
Real-World Evidence
A prospective observational study of 111 patients demonstrated that apixaban discontinuation for at least 48 hours before a procedure resulted in clinically insignificant anticoagulation (94% had concentrations ≤30 ng/mL), with only one clinically significant nonmajor bleeding event reported 6
