8 Use in Specific Populations

8.1 Pregnancy

(PLLR conversion)

Risk Summary

Administration of the approved recommended dose of CaloMist is not expected to cause major birth defects, miscarriage or adverse maternal or fetal outcomes. Animal reproduction studies have not been conducted with CaloMist nasal spray. There are risks associated with vitamin B12 deficiency during pregnancy (see Clinical Considerations).

The estimated background risk of major birth defects and miscarriage for the indicated population 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.

Clinical Considerations

Disease-associated maternal and/or embryo/fetal risk

Severe maternal vitamin B12 deficiency during pregnancy may result in adverse pregnancy outcomes such as low birth weight, preterm birth and megaloblastic anemia.

8.2 Lactation

(PLLR conversion)

Risk Summary

Vitamin B12 is present in human milk. Administration of the approved recommended dose of CaloMist is not expected to cause harm to a breastfed child. There is no information on the effects of CaloMist on the breastfed child or on milk production. The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for CaloMist and any potential adverse effects on the breastfed infant from the underlying maternal condition.
