Should a patient who stopped taking Eliquis (apixaban) 3 months ago be restarted on the medication in the emergency room (ER)?

Should Eliquis Be Restarted in the ER After 3 Months of Discontinuation?

The decision to restart Eliquis (apixaban) in the ER depends entirely on whether the patient still has a valid indication for anticoagulation and whether any contraindications exist—the 3-month gap itself is not the determining factor. 1

Critical First Step: Determine if Anticoagulation Indication Still Exists

You must immediately assess whether the original indication for anticoagulation remains valid or has resolved 1:

Discontinue anticoagulation permanently if ANY of the following apply:

• Nonvalvular atrial fibrillation with CHA₂DS₂-VASc score <2 in men or <3 in women 1
• Temporary indication that has been completed (e.g., post-surgical prophylaxis, post-LAA closure device placement >3 months ago) 1
• First-time provoked VTE that occurred >3 months ago 1
• Bioprosthetic valve placement in the absence of atrial fibrillation >3 months ago 1

Restart anticoagulation if the patient has a persistent high-risk indication:

• Mechanical heart valve (especially mitral position) 1
• Nonvalvular atrial fibrillation with CHA₂DS₂-VASc score ≥4 or recent stroke/TIA within 3 months 1
• VTE within 3 months, unprovoked VTE, recurrent VTE, or cancer-associated VTE 1
• Left atrial or left ventricular thrombus 1
• Left ventricular assist device 1

Assess for Contraindications to Restarting

Delay or avoid restarting anticoagulation if ANY of the following apply: 1

• Active bleeding at a critical site (intracranial, intraspinal, intraocular, pericardial, intra-articular, intramuscular with compartment syndrome, retroperitoneal) 1
• Patient is at high risk of rebleeding or death/disability with rebleeding 1
• Source of previous bleeding has not been identified or treated 1
• Surgical or invasive procedure is planned 1
• Patient declines after informed discussion 1

Why the Patient Stopped Matters

Critical pitfall: The FDA label explicitly warns that stopping apixaban increases stroke risk, and discontinuation should never occur without physician consultation 2. If the patient self-discontinued without medical guidance 3 months ago, they have been at elevated thrombotic risk during this entire period.

Research demonstrates that premature discontinuation of apixaban is associated with high 30-day rates of death (5.8%), thromboembolism (2.6%), and major bleeding (3.0%) 3. The most common reasons for discontinuation are patient request (46.1%) and adverse events (34.9%) 3.

Practical ER Management Algorithm

If valid indication exists and no contraindications:

1. Restart apixaban immediately in the ER at the appropriate dose based on indication, age, weight, and renal function 1, 4
2. Verify appropriate dosing: 5 mg twice daily (or 2.5 mg twice daily if ≥2 of the following: age ≥80 years, weight ≤60 kg, serum creatinine ≥1.5 mg/dL) 2
3. Counsel patient on the critical importance of adherence and risks of discontinuation 2
4. Arrange close outpatient follow-up to address reasons for initial discontinuation 3

If patient had prior bleeding:

• The American College of Cardiology recommends that decisions should be made by a multidisciplinary care team, but in the ER setting, prioritize thrombotic risk over bleeding risk for high-risk indications 1, 4
• For patients with high thrombotic risk (mechanical valve, recent stroke/TIA, recent VTE), restart anticoagulation even if rebleeding risk is elevated 1, 4
• Consider starting with parenteral anticoagulation (unfractionated heparin) if rebleeding risk is very high, as it has a short half-life and reversibility with protamine 1

If indication is unclear or patient is unstable:

• Do not restart in the ER 1
• Arrange urgent outpatient cardiology or hematology follow-up within 24-48 hours 1
• Consider prophylactic-dose anticoagulation as a bridge if thrombotic risk is moderate-to-high 1

Key Safety Considerations

The FDA label emphasizes that stopping apixaban increases stroke risk, particularly in atrial fibrillation patients 2. After 3 months off anticoagulation, the patient has been exposed to this elevated risk for an extended period.

Common pitfall: Do not assume that because the patient has been off anticoagulation for 3 months without an event, they no longer need it. The thrombotic risk is cumulative and ongoing 2, 3.

Apixaban has a half-life of approximately 12 hours, so after 3 months of discontinuation, there is no residual drug effect 5. Restarting carries the same bleeding risk as initial therapy, which must be weighed against the ongoing thrombotic risk 6, 7.
