Pregnancy: There are no adequate data from the use of pegfilgrastim in pregnant women.
Studies in animals have shown reproductive toxicity (see Pharmacology: Toxicology: Preclinical Safety Data under Actions).
The potential risk for humans is unknown.
Pegfilgrastim should not be used during pregnancy unless clearly necessary.
Breastfeeding: There is no clinical experience with breast-feeding women therefore, pegfilgrastim should not be administered to women who are breast-feeding.
