Factor Xa Inhibitors

Anticoagulant Half-life Removed by HD Strategies to reverse or minimize anticoagulant effects
Apixaban (Eliquis®) 8-15 hrs (longer in renal impairment) No
  • If ingested within 2 hours, administer activated charcoal
  • 4-factor PCC (Kcentra™)^
    • 25units/kg—max 2500 units for treatment of documented intracranial hemorrhage
    • 50 units/kg—max 5000 units for all other life-threatening bleeds
Edoxaban (Savaysa®) 10-14 hrs (longer in renal impairment) ~ 25% As above
Rivaroxaban (Xarelto®) 9-13 hrs (longer in renal impairment) No As above
Fondaparinux (Arixtra®) 17-21 hrs (significantly longer in renal impairment) No 4-factor PCC (Kcentra™)^ 50 units/kg—max 5000 units

Direct Thrombin Inhibitor

Anticoagulants Half-life Removed by HD Strategies to reverse or minimize anticoagulant effects
Argatroban 40-50 min ~ 20% Turn off infusion
Bivalirudin (Angiomax®) 25 min (up to 1 hr in severe renal impairment) ~ 25% As above
Dabigatran (Pradaxa®) 14-17 hrs (up to 34 hrs in severe renal impairment) ~ 65%
  • If ingested within 2 hours, administer activated charcoal
  • Idarucizumab (Praxbind®) 5g IV
  • For end stage renal disease patient with pre-existing vascular access, consult nephrology to consider dialysis.

Heparins

Anticoagulants Half-life Removed by HD Strategies to reverse or minimize anticoagulant effects
Dalteparin (Fragmin®) 3-5 hrs (longer in renal impairment) ~ 20%
  • Use protamine for partial neutralization (~60%)
  • Protamine IV:
    • < 8 hours since last LMWH dose: Protamine 50 mg
    • 8-12 hours since last LMWH dose: Protamine 25 mg
    • >12 hours since last LMWH dose: Unlikely useful unless CrCl < 30 mL/min (or 25mg fixed dose)
  • Dose of protamine for each 100 units dalteparin or 1mg of enoxaparin administered
  • Obtain baseline anti-Xa activity level
  • Monitor anti-Xa activity level to confirm reversal
Enoxaparin (Lovenox®) As above
Heparin 30-90 min (dose dependent) Partial
  • Turn off infusion
  • Protamine 50 mg IV
