Insulin zinc Pregnancy Warnings

Insulin has been assigned to pregnancy category B by the FDA. Insulin regular is the drug of choice for the treatment of diabetes during pregnancy. Data from human pregnancy have revealed an increased incidence of teratogenicity associated with diabetes mellitus; the association with the use of insulin is probably coincidental. Because of the strong association between diabetes or hyperglycemia and perinatal morbidity and multiple congenital malformations, most experts recommend strict control of maternal plasma glucose with the use of insulin during pregnancy. Insulin is only recommended for use during pregnancy when benefit outweighs risk.

Insulin zinc Breastfeeding Warnings

Insulin is not excreted into human milk. Breast-feeding, however, may decrease insulin requirements, despite the need for increased caloric intake. Careful observation of increased maternal caloric needs and maternal blood glucose levels are needed. The manufacturer recommends that caution be used when administering insulin to nursing women.
