What is the washout period for Eliquis (apixaban)?

Eliquis (Apixaban) Washout Period

For patients with normal renal function (CrCl >50 mL/min), Eliquis requires 48 hours (2 days) to washout for low-risk procedures and 72 hours (3 days) for high-risk procedures. 1

Washout Duration Based on Renal Function and Procedure Risk

Normal Renal Function (CrCl >30 mL/min)

• Low-risk procedures: Omit the morning dose on the day of procedure (essentially 12-24 hours) 1
• High-risk procedures: Stop 2-3 days before (skip 2-4 doses) 1
• The FDA label specifies discontinuation at least 48 hours prior to elective surgery with moderate-to-high bleeding risk, or 24 hours for low bleeding risk procedures 2

Impaired Renal Function (CrCl 15-30 mL/min)

• High-risk procedures: Stop 4 days before (skip 6 doses) 1
• The half-life extends to approximately 27 hours in severe renal impairment, requiring longer washout 3

Pharmacokinetic Basis for Washout Timing

The washout recommendations are based on apixaban's half-life of 10-15 hours (median 12 hours) in patients with normal renal function. 1, 3

• Five half-lives equals approximately 60 hours (2.5 days), at which point 97% of the drug is eliminated 3
• Each 12-hour dosing interval represents approximately one half-life 3
• After 48 hours (2 days), approximately 94% of apixaban is eliminated, leaving minimal residual anticoagulant effect (3-6%) 3

Evidence from Clinical Studies

The PAUSE trial validated these washout protocols in 3,007 patients, demonstrating low rates of major bleeding and thromboembolism when apixaban was stopped 2 days before low-risk procedures and 3 days before high-risk procedures. 1

• A prospective observational study (ADIOS) confirmed that 94% of patients achieved clinically insignificant apixaban concentrations (≤30 ng/mL) after a median of 76 hours off the drug 4
• Real-world data supports that discontinuation for at least 48 hours results in minimal anticoagulation prior to surgery 4

Critical Considerations

Renal function is the most important factor affecting washout duration because apixaban has 25-27% renal elimination. 1

• Patients with CrCl 30-50 mL/min may require an extra day of washout for high-risk procedures 1
• Apixaban is contraindicated or not recommended when CrCl <15 mL/min 1
• The pharmacodynamic effect persists for at least 24 hours after the last dose (approximately two half-lives) 2

Common Pitfalls to Avoid

• Do not rely on PT, INR, or aPTT to assess residual anticoagulation - these tests are unreliable for DOACs 1
• Do not use bridging anticoagulation during the washout period unless there is a prolonged interruption beyond the recommended timeframe 1
• Do not assume the same washout applies to all DOACs - dabigatran requires longer interruption (up to 5 days with reduced renal function) 1
• Verify renal function before determining washout duration, especially in elderly patients or those with borderline kidney function 1

Resumption After Procedure

Restart apixaban after adequate hemostasis is established, typically 24 hours after low bleeding risk procedures and 48-72 hours after high bleeding risk procedures. 1, 2

• The FDA label states to restart "as soon as adequate hemostasis has been established" 2
• For major surgery, consider using reduced-dose apixaban (2.5 mg twice daily) for the first 1-2 days before resuming full dose 1
