Apixaban Discontinuation Before Surgery
For elective surgery, stop apixaban 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
Bleeding Risk Classification
High bleeding risk procedures include: 1
- Cardiac surgery
- Intracranial or spinal surgery
- Major abdominal surgery (e.g., liver resection, pancreatic surgery)
- Major orthopedic surgery (hip/knee replacement)
- Procedures with duration >45 minutes in highly vascular organs
- Neuraxial anesthesia (spinal/epidural)
Low-to-moderate bleeding risk procedures include: 1
- Arthroscopy
- Colonoscopy with biopsy
- Laparoscopic cholecystectomy
- Abdominal hernia repair
- Coronary angiography (radial approach)
- Abdominal hysterectomy
Minimal bleeding risk procedures (can continue apixaban or hold morning dose only): 1
- Cataract surgery
- Minor dental procedures (extractions, fillings)
- Minor dermatologic procedures
- Pacemaker/ICD implantation
Standard Discontinuation Protocol
For patients with normal renal function (CrCl ≥80 mL/min): 1
- Low-to-moderate bleeding risk: Stop 1 day (24 hours) before surgery—this achieves 2-3 half-lives with 3-6% residual anticoagulant effect
- High bleeding risk: Stop 2 days (48 hours) before surgery—this achieves 4 half-lives with minimal residual effect
The PAUSE trial validated this approach in 1,257 apixaban patients, demonstrating arterial thromboembolism rates of 0.16% and major bleeding rates of 1.35%, confirming safety and efficacy. 1
Renal Impairment Adjustments
Apixaban elimination is 27% renal, requiring extended interruption in renal dysfunction: 2, 3
For CrCl 50-79 mL/min: 1
- Low-to-moderate bleeding risk: Stop 24 hours before (same as normal function)
- High bleeding risk: Stop 48 hours before (same as normal function)
For CrCl 30-49 mL/min: 1
- Low-to-moderate bleeding risk: Stop 24 hours before
- High bleeding risk: Stop 48 hours before
For CrCl 15-29 mL/min: 1
- Low-to-moderate bleeding risk: Stop 36 hours before
- High bleeding risk: Stop 48 hours before
Critical warning: Patients with severe chronic kidney disease can accumulate apixaban and experience catastrophic bleeding including pleural, pericardial, and intracranial hemorrhage. 2 Extended preoperative interruption is essential even if baseline renal function was acceptable, as declining function increases bleeding risk. 2
Special Considerations for Neuraxial Procedures
For spinal or epidural anesthesia, stop apixaban for a full 72 hours (3 days) regardless of renal function. 3 This extended duration accounts for the catastrophic consequences of epidural hematoma and associated lower limb paralysis, even though the absolute bleeding risk may be low. 1
Drug Interactions Requiring Extended Interruption
For patients taking concomitant P-gp inhibitors (dronedarone, amiodarone, verapamil): 1
- Consider adding an extra 24 hours of interruption, especially if thromboembolic risk is not very high (CHA2DS2-VASc <2-3)
- These medications reduce apixaban clearance and prolong its effect
FDA-Approved Discontinuation Guidance
The FDA label states apixaban should be discontinued: 4
- At least 48 hours prior to elective surgery with moderate or high bleeding risk
- At least 24 hours prior to elective surgery with low bleeding risk or where bleeding would be non-critical and easily controlled
This FDA guidance is more conservative than the ACCP guidelines but provides a safe default approach. 4
Bridging Anticoagulation
Do NOT use bridging with heparin or low molecular weight heparin during the interruption period. 1, 2, 4 The rapid offset and onset of apixaban obviates the need for bridging, and mixing two anticoagulants increases bleeding risk without reducing thromboembolism. 1 The PAUSE trial demonstrated this approach is safe without bridging. 1
Laboratory Monitoring Pitfalls
Standard coagulation tests (INR, aPTT) are unreliable for assessing apixaban effect and should NOT guide surgical timing. 2, 3 If measurement is needed, use DOAC-calibrated anti-factor Xa levels, though clinical utility remains uncertain. 1 A real-world study showed that 94% of patients achieved apixaban concentrations ≤30 ng/mL after discontinuation for at least 48 hours. 5
Postoperative Resumption
Resume apixaban at least 24 hours after low-to-moderate bleeding risk surgery once adequate hemostasis is established. 1, 2, 4
For high bleeding risk surgery, resume 48-72 hours postoperatively. 1, 2 Apixaban's rapid onset of action (peak effect 1-3 hours after intake) requires cautious administration to avoid bleeding if hemostasis is incomplete. 1, 2
Common Pitfalls to Avoid
- Never double the dose to compensate for a missed preoperative dose—this increases bleeding risk 4
- Avoid premature resumption after high-risk surgery—apixaban's rapid onset can precipitate major bleeding 2
- Do not rely on INR or aPTT for surgical clearance—these tests are inconsistent with apixaban 3
- Account for postoperative factors affecting absorption (bowel dysmotility, acid-suppressive therapy) after major abdominal surgery 2
