Pegfilgrastim is contraindicated in patients with known hypersensitivity to E. coli-derived proteins.

Pegfilgrastim should not be administered in the period between 14 days before and 24 hours after the administration of cytotoxic chemotherapy.

Splenic rupture has been reported rarely following the administration of filgrastim, the parent compound of pegfilgrastim, when used for peripheral blood progenitor cell (PBPC) mobilization in both healthy donors and patients with cancer. Pegfilgrastim has not been evaluated in this setting, therefore, should not be used for PBPC mobilization. Patients receiving pegfilgrastim who report left upper abdominal or shoulder tip pain should be evaluated for an enlarged spleen or splenic rupture.

Adult respiratory distress syndrome (ARDS) has been reported with the use of filgrastim, therefore, patients receiving pegfilgrastim who develop fever, lung infiltrates, or respiratory distress should be evaluated for the possibility of ARDS.

Although allergic-type reactions were not observed during clinical trials of pegfilgrastim, some cases related to the administration of the parent compound, filgrastim, have been reported. If a serious allergic reaction or an anaphylactic reaction occurs with the use of pegfilgrastim, appropriate therapy should be administered and further use of pegfilgrastim should be discontinued.

Patients with sickle cell disease who receive pegfilgrastim should be kept well hydrated and monitored for the occurrence of sickle cell crisis.
