Summary of Use during Lactation

No information is available on the use of brolucizumab during breastfeeding. Brolucizumab inhibits vascular endothelial growth factor (VEGF). Because it is a large protein molecule with a molecular weight of 26,000 Da, the amount in milk is likely to be very low. It is also likely to be partially destroyed in the infant's gastrointestinal tract and absorption by the infant is probably minimal. Since VEGF is present in human milk and is thought to help in maturation of the infant’s gastrointestinal tract, concern has been raised about the maternal use of VEGF inhibitors during breastfeeding. Note that the typical alternative to breastmilk is infant formula, which contains no VEGF.
