Dose Modifications
ZEJULA dose modifications to manage adverse reactions1


If hematological toxicities do not resolve within 28 days following interruption, discontinue ZEJULA and refer the patient to a hematologist for further investigation.
Resume at the same dose only for the first occurrence of thrombocytopenia if platelets are >75,000/μL.
Monitoring complete blood counts, blood pressure, and heart rate helps identify the need to dose modify1
Blood counts

2-3 months
Blood pressure and heart rate

No starting dose adjustment necessary for most special populations or conditions1
Dose adjustment
For Moderate Hepatic
Impairment§

Total bilirubin ≥1.5 x ULN to 3.0 x ULN and any AST level||
For patients with moderate hepatic impairment, reduce the starting dosage of ZEJULA to 200 mg once daily.1
Monitor patients for hematologic toxicity and reduce the dose further, if needed.

For Moderate Hepatic
Impairment§
Total bilirubin ≥1.5 x ULN to 3.0 x ULN and any AST level||
For patients with moderate hepatic impairment, reduce the starting dosage of ZEJULA to 200 mg once daily.1
Monitor patients for hematologic toxicity and reduce the dose further, if needed.
No dose adjustment necessary1

There are no data in patients with severe hepatic impairment.
There are no data in patients with severe renal impairment or end-stage renal disease undergoing hemodialysis.
