Pregnancy
8.1 Pregnancy Risk Summary Based on findings from animal studies, micafungin may cause fetal harm when administered to a pregnant woman (see Data ) . There is insufficient human data on the use of micafungin in pregnant women to inform a drug-associated risk of adverse developmental outcomes. In animal reproduction studies, intravenous administration of micafungin sodium to pregnant rabbits during organogenesis at doses four times the maximum recommended human dose resulted in visceral abnormalities and increased abortion (see Data ) . Advise pregnant women of the risk to the fetus.
