For a patient scheduled for a lumbar puncture tomorrow, should I hold the apixaban (Eliquis) dose tonight and the morning dose before the procedure?

Yes, hold both doses of apixaban before the lumbar puncture

For a lumbar puncture scheduled tomorrow, you should hold both tonight's and tomorrow morning's doses of apixaban (Eliquis), with the last dose being taken this morning (approximately 48 hours before the procedure). Lumbar puncture is classified as a high hemorrhagic risk procedure—specifically neuraxial puncture—due to the catastrophic consequences of spinal hematoma, which requires a longer interruption window than standard procedures.

Risk Classification and Timing

Lumbar puncture falls into the very high hemorrhagic risk category because:

• Surgical hemostasis cannot be performed in the spinal canal
• Bleeding in this location can cause permanent neurological damage
• The procedure involves neuraxial puncture where even small hematomas can compress neural structures

The French GIHP guidelines explicitly state that "very high hemorrhagic risk such as intracranial neurosurgery or neuraxial anesthesia/puncture needs a longer interruption time of DOACs prior to the planned procedure up to five days for xabans and dabigatran in the absence of renal failure" 1. They further emphasize: "The entire group strongly recommends not performing spinal or epidural anesthesia or deep-block techniques in patients with a possible DOA concentration (insufficient discontinuation time)" 1.

Specific Timing for Apixaban

Since apixaban is dosed twice daily (typically 5 mg BID):

For high-risk procedures with normal renal function:

• The last dose should be taken 2-3 days before the procedure 2
• This translates to holding 4-6 doses before the procedure 3
• The FDA label specifies: "ELIQUIS 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" 4

Your specific timeline (if LP is tomorrow morning):

• Hold tonight's dose (approximately 36 hours before procedure)
• Hold tomorrow morning's dose (approximately 24 hours before procedure)
• Last dose taken: this morning (approximately 48 hours before procedure)

This achieves the minimum 48-hour interruption required by the FDA label and approaches the 3-day window recommended for very high-risk procedures.

Critical Considerations

Renal function matters significantly:

• If your patient has CrCl <30 mL/min, apixaban clearance is impaired and you may need 3-4 days of interruption 1
• Check recent creatinine clearance before proceeding 1

No bridging anticoagulation is needed:

• The 2017 French guidelines explicitly state: "preoperative bridging by UFH or LMWH is not recommended" for DOACs 1
• The 2024 AHA/ACC guidelines confirm bridging is "not generally required" 5
• The FDA label states: "Bridging anticoagulation during the 24 to 48 hours after stopping ELIQUIS and prior to the intervention is not generally required" 4

Thrombotic risk assessment:

• If your patient has very high thrombotic risk (recent stroke/TIA within 3 months, mechanical valve, CHADS₂ ≥3), consider whether the LP can be delayed to allow safer anticoagulation interruption 2
• However, bridging is still not recommended even in high-risk patients due to increased bleeding without thrombotic benefit 1

Common Pitfalls to Avoid

1. Don't assume 24 hours is sufficient for neuraxial procedures—this applies only to low-risk procedures 4

2. Don't bridge with heparin—this increases bleeding risk without reducing thrombotic events 1

3. Don't forget to check renal function—impaired clearance requires longer interruption 1

4. Don't measure apixaban levels routinely—the French guidelines state "there is no reason to measure the concentration of DOA before the procedure" for elective cases 1

Resumption After Procedure

Resume apixaban 48-72 hours after the lumbar puncture once hemostasis is confirmed and there are no signs of spinal hematoma 2, 1. The FDA label states: "ELIQUIS should be restarted after the surgical or other procedures as soon as adequate hemostasis has been established" 4.

Monitor closely for signs of spinal hematoma (back pain, leg weakness, bowel/bladder dysfunction) in the first 24-48 hours post-procedure 4.
