Insulin degludec in the first trimester of pregnancy: Report of two cases
Insulin degludec is an extra-long-acting insulin analog that allows for enhanced efficacy and flexibility in the injection time. However, it is not approved for use during pregnancy. We report the pregnancy outcome and newborn conditions in two women with type 1 diabetes who continued preconception degludec treatment during embryogenesis. No pregnancy complication or congenital neonatal malformation was observed. Both babies presented with hypoglycemia and required neonatal intensive care unit admission. Degludec treatment did not cause adverse effects in the mothers or malformations in the newborns. The observed neonatal complications were probably independent of early pregnancy degludec treatment.
