Obiltoxaximab

No information is available on the clinical use of obiltoxaximab during breastfeeding. Because obiltoxaximab is a large protein molecule with a molecular weight of 148,000, the amount in milk is likely to be very low.[1] It is also likely to be partially destroyed in the infant's gastrointestinal tract and absorption by the infant is probably minimal.[2] Until more data become available, obiltoxaximab should be used with caution during breastfeeding, especially while nursing a newborn or preterm infant. Waiting for at least 2 weeks postpartum to resume therapy may minimize transfer to the infant.[3]
