Omalizumab Levels and Effects while Breastfeeding

Summary of Use during Lactation

No information is available on the clinical use of omalizumab during breastfeeding. Because omalizumab is a large protein molecule with a molecular weight of 145,058, the amount in milk is likely to be very low and absorption is unlikely because it is probably destroyed in the infant's gastrointestinal tract. Until more data become available, omalizumab should be used with caution during breastfeeding, especially while nursing a newborn or preterm infant.
