How long should apixaban (apixaban) be suspended before surgery in a patient with normal renal function?

Apixaban Suspension Before Surgery in Patients with Normal Renal Function

For patients with normal renal function, apixaban should be discontinued 48 hours (2 days) before low-to-moderate bleeding risk procedures and 72 hours (3 days) before high bleeding risk procedures. 1, 2

Discontinuation Timeline Based on Bleeding Risk

Low-to-Moderate Bleeding Risk Procedures

• Hold apixaban for 48 hours (2 days) before surgery, which corresponds to 2-3 half-lives and allows for mild residual anticoagulant effect 1, 2
• The FDA label specifically states apixaban should be discontinued at least 24 hours prior to elective surgery with low bleeding risk, though the American College of Chest Physicians recommends the more conservative 48-hour window 2, 1
• Examples include arthroscopy, laparoscopic cholecystectomy, abdominal hernia repair, colonoscopy with biopsy, and coronary angiography 1

High Bleeding Risk Procedures

• Hold apixaban for 72 hours (3 days) before surgery, corresponding to 4-5 half-lives to achieve minimal residual anticoagulant effect 1, 2
• The FDA label mandates at least 48 hours for moderate-to-high bleeding risk procedures, though guidelines recommend 72 hours for optimal safety 2, 1
• High-risk procedures include cardiac surgery, intracranial or spinal surgery, surgery in highly vascular organs, and any major operation 1

Special Consideration: Neuraxial Procedures

• A full 72-hour (3-day) discontinuation period is mandatory for neuraxial procedures (spinal/epidural anesthesia) even in patients with normal renal function, due to the catastrophic risk of epidural hematoma 1, 3

Pharmacokinetic Rationale

• Apixaban has a half-life of 7-8 hours in patients with normal renal function, with only 27% renal clearance 1, 4
• Maximum concentration occurs 3-4 hours after oral administration 4
• Real-world evidence confirms that discontinuation for at least 48 hours results in clinically insignificant anticoagulation (94% of patients achieved apixaban concentrations ≤30 ng/mL) 5

Critical Management Points

No Bridging Required

• Bridging anticoagulation is NOT required during the 24-72 hour interruption period due to apixaban's rapid offset and onset of action 1, 2
• This represents a key advantage over warfarin management and simplifies perioperative care 3

Postoperative Resumption

• Resume apixaban at least 24 hours after surgery once adequate hemostasis is established 1, 2
• For high bleeding risk procedures, consider delaying resumption to 48-72 hours postoperatively 1
• The rapid onset of action (peak levels at 3-4 hours) necessitates caution when restarting therapy 4

Common Pitfalls to Avoid

• Do not use INR or aPTT to guide timing: While prothrombin time may provide some information, apixaban's effect on these tests is inconsistent and they should not be relied upon for surgical clearance 3
• Verify renal function before applying these guidelines: These recommendations apply ONLY to patients with normal renal function; moderate-to-severe renal impairment requires longer discontinuation periods 1, 4
• Do not double-dose after missed doses: If surgery is delayed, resume the regular twice-daily schedule without dose adjustment 2
• Avoid procedures with cardiac perforation risk without adequate drug clearance: For catheter ablation or procedures where cardiac tamponade is possible, ensure complete drug elimination as no specific reversal agent is readily available 3
