Interactions between your drugs
peginterferon alfa-2b pegfilgrastim
Applies to: peginterferon alfa-2b, Ziextenzo (pegfilgrastim)
ADJUST DOSING INTERVAL: The safety and efficacy of recombinant human granulocyte colony-stimulating factors (rhG-CSF) administered simultaneously with cytotoxic agents, including cancer chemotherapy, have not been established. Theoretical concerns exist regarding their concomitant administration because hematopoietic growth factors stimulate myeloid cell proliferation while antineoplastic agents primarily target rapidly dividing cells.
MANAGEMENT: The prescribing information for pegfilgrastim, eflapegrastim, and efbemalenograstim alfa recommends that these products not be administered between 14 days before and 24 hours after antineoplastic agents.
