    • Patients at high risk for thrombosis, such as patients with thrombophilia and those who have a history of thromboembolic events (especially unprovoked thrombosis), should be advised to avoid the drug.
    • Patients with chronic liver disease, including portal vein thrombosis treatment-emergent, have also experienced thrombotic events.
    • Patients with ongoing thrombosis and patients without hepatopetal bloodflow, as well as those with a history of thrombosis should not use Lusutrombopag unless the benefits outweigh the risk.

Monitor:

Monitor platelet counts at baseline and at least 2 days prior to a scheduled procedure. Monitor the clinical features of thromboembolism and adherence to the drug.
