Comorbidity-specific recommendationsRecommended for patients with antiphospholipid syndromeRecommended for patients with active cancer with no gastrointestinal or genitourinary involvement: rivaroxaban, apixaban, or edoxaban
Recommended for patients with cancer with gastrointestinal or genitourinary involvement: apixaban
For patients with recent acute coronary syndrome, avoid dabigatran
Recommended for patients with active cancer and for pregnant patientsRecommended for patients with high-risk superficial vein thrombosis
Liver dysfunction considerationsCan be used in patients with increased prothrombin time or INRAvoid in patients with increased prothrombin time or INRCan be used in patients with increased prothrombin time or INRRecommended for patients with high-risk superficial vein thrombosis; use with caution, monitor closely for signs of bleeding
Renal dysfunction considerationsCan be used in patients with creatinine clearance rate < 30 mL/minFor patients with creatinine clearance 30–50 mL/min, preferred agents are rivaroxaban, apixaban, or edoxaban
Avoid all direct oral anticoagulants in patients with creatinine clearance rate < 30 mL/min
Use doses adjusted for renal function as recommended in product labelingAvoid in patients with creatinine clearance rate < 30 mL/min
  • INR = international normalized ratio
