Filspari Pregnancy Warnings
Animal studies have revealed evidence of embryo-fetal lethality, teratogenicity, and reduced fetal weights; these outcomes were attributed to the antagonism of endothelin type A and angiotensin II type 1 receptors. Animal studies suggest there are no impairments to fertility with this drug. There are insufficient controlled data in human pregnancy.
