Premalignant or malignant myeloid condition; sickle-cell disease; osteoporotic bone disease; withdraw treatment if there are signs of pulmonary infiltrates. Fluid retention or heart failure. Monitor CBC and platelet count during therapy. Monitor bone density in patients with osteoporosis (long-term treatment). Regular morphological and cytogenic bone-marrow examinations in severe congenital neutropenia. Pregnancy and lactation. Lactation: excretion in milk unknown; use with caution

Pregnancy-Lactation

Pregnancy Available data from published studies, including several observational studies of pregnancy outcomes in women exposed to filgrastim products and those who were unexposed, have not established an association with use during pregnancy and major birth defects, miscarriage, or adverse maternal or fetal outcomes Reports in scientific literature have described transplacental passage of drug in pregnant women when administered less than or equal to 30 hours prior to preterm delivery (less than or equal to 30 weeks' gestation) In animal reproduction studies, effects of filgrastim on prenatal development have been studied in rats and rabbits; no malformations were observed in either species; no maternal or fetal effects were observed in pregnant rats at doses up to 58 times the human doses; drug has been shown to have adverse effects in pregnant rabbits at doses 2 -10 times higher than the human doses Lactation There is published literature documenting transfer of filgrastim into human milk; there are a few case reports describing use of filgrastim in breastfeeding mothers with no adverse effects noted in the infants; there are no data on effects of filgrastim on milk production; other filgrastim products are secreted poorly into breast milk, and filgrastim products are not absorbed orally by neonates; developmental and health benefits of breastfeeding should be considered along with mother’s clinical need for therapy and any potential adverse effects on the breastfed child from the drug or from underlying maternal condition
