What to do next for a patient with Deep Vein Thrombosis (DVT) on Eliquis (apixaban) who develops hematuria?

Management of Hematuria in a Patient on Eliquis (Apixaban) for DVT

Stop apixaban immediately, assess bleeding severity, provide supportive care, and investigate for underlying urological pathology before considering resumption of anticoagulation. 1

Immediate Assessment and Management

Determine Bleeding Severity

• Assess for major bleeding criteria: bleeding at a critical site, hemodynamic instability, hemoglobin decrease ≥2 g/dL, or need for ≥2 units of blood transfusion 1
• For major bleeding: stop apixaban immediately, provide local therapy if applicable, initiate volume resuscitation, and assess for comorbidities contributing to bleeding 1
• For life-threatening bleeding: consider reversal agents such as andexanet alfa (specific for apixaban) or prothrombin complex concentrates (PCCs) 2, 1
• For mild to moderate hematuria: most cases can be controlled by holding anticoagulation for less than 2 days 3

Supportive Care Measures

• Do not remove urinary catheters or restrict patient mobility, as these measures do not reduce rebleeding rates 3
• Avoid platelet transfusions unless there is active life-threatening bleeding, as routine platelet transfusion is not recommended 2
• Monitor hemoglobin and vital signs closely during the initial management period 1

Investigation for Underlying Pathology

Mandatory Urological Evaluation

• Rule out urinary tract malignancy, which is mandatory in all patients presenting with hematuria on anticoagulation 3
• Perform appropriate imaging and cystoscopy once bleeding is controlled to identify any structural or malignant causes 3
• Baseline D-dimer and coagulation markers were elevated in patients with acute DVT but do not predict bleeding events 4

Decision to Resume Anticoagulation

Risk-Benefit Assessment

• Evaluate thrombotic risk: for unprovoked DVT, stopping anticoagulation significantly increases recurrent VTE risk 1
• Assess if bleeding source has been identified and addressed before restarting therapy 1
• Consider high rebleeding risk: hematuria recurrence is more common in female patients and is dose-dependent 3

Timing and Agent Selection

• Resume apixaban at least 6 hours after hemostasis is achieved if bleeding is controlled and anticoagulation remains essential 1
• Consider alternative anticoagulation strategies: switching to low-molecular-weight heparin (LMWH) or non-vitamin K dependent oral agents may reduce recurrence of hematuria compared to continuing the same agent 3
• For cancer-associated DVT: prefer LMWH over DOACs, particularly in patients with luminal GI malignancies where bleeding risk is higher 2
• Extended anticoagulation is recommended for unprovoked DVT (no scheduled stop date), as this represents recurrent disease requiring indefinite therapy 2, 5

Alternative Options if Apixaban is Contraindicated

• Switch to rivaroxaban, dabigatran, or edoxaban as acceptable DOAC alternatives for VTE treatment 6
• Consider warfarin with careful INR monitoring (target INR 2.0-3.0) if DOACs are deemed too high-risk 2, 1
• Aspirin 81-100 mg daily provides modest protection if anticoagulation must be permanently discontinued, though this is inferior to full anticoagulation 1

Ongoing Monitoring

Follow-up Requirements

• Reassess at 3 months to confirm therapeutic response and tolerance 5
• Annual reassessment is mandatory if extended anticoagulation continues, with attention to renal function (apixaban contraindicated if CrCl <15 mL/min), bleeding history, and fall risk 1, 7
• After 6 months of therapeutic dosing: consider transition to reduced-dose apixaban 2.5 mg BID for extended therapy if bleeding risk is acceptable 5

Key Clinical Pitfalls to Avoid

• Do not use prothrombin time (PT), INR, or aPTT to monitor apixaban effect, as these tests are not useful for factor Xa inhibitors 2
• Hemodialysis does not substantially remove apixaban, so this is not an effective reversal strategy 7
• Activated charcoal reduces apixaban absorption only if given shortly after ingestion 7
• Hematuria typically starts within the first 72 hours of therapy and is anticoagulant dose-dependent, so early vigilance is critical 3
• Antiplatelet therapy continuation does not increase rebleeding rates and can be maintained if indicated 3
