Pregnancy & Breastfeeding
8.1 Pregnancy Risk Summary There are no available data on Cysview use in pregnant women to inform a drug associated risk of adverse developmental outcomes. Adequate reproductive and developmental toxicity studies in animals have not been performed. Systemic absorption following administration of Cysview is expected to be minimal [see Clinical Pharmacology (12.3) ]. The background risk of major birth defects and miscarriage for the indicated populations is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2-4% and 15-20%, respectively.
