Pregnancy
8.1 Pregnancy Risk Summary Although rare case reports of Carglumic acid tablets for oral suspension use in pregnant women are insufficient to inform a drug-associated risk of major birth defects, miscarriage, or adverse maternal or fetal outcomes, untreated NAGS deficiency can result in irreversible neurologic damage and death in pregnant women [see Clinical Considerations]. In an animal reproduction study, decreased survival and growth occurred in offspring born to rats that received carglumic acid at a dose approximately 38 times the maximum reported human maintenance dose.
