Halaven Use In Pregnancy & Lactation

Pregnancy: There are no data on the use of eribulin in pregnant women. Eribulin is embryotoxic, foetotoxic and teratogenic in rats. HALAVEN should not be used during pregnancy unless clearly necessary and after a careful consideration of the needs of the mother and the risk to the foetus.
Women of childbearing potential must be advised to avoid becoming pregnant whilst they or their male partner are receiving HALAVEN and have to use effective contraception during and up to 3 months after treatment.
Fertility: Testicular toxicity has been observed in rats and dogs (see Pharmacology: Toxicology: Preclinical Safety Data under Actions). Male patients should seek advice on conservation of sperm prior to treatment because of the possibility of irreversible infertility due to therapy with HALAVEN.
Breast-feeding: It is unknown whether eribulin/metabolites are excreted in human or animal breast milk. A risk to newborns/infants cannot be excluded and therefore HALAVEN must not be used during breast-feeding (see Contraindications).
