Tralokinumab use while Breastfeeding

Summary of Use during Lactation

No information is available on the clinical use of tralokinumab during breastfeeding. Because tralokinumab is a large protein molecule with a molecular weight of 147,000 Da, 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] Some expert opinions consider tralokinumab acceptable during breastfeeding.[3] Until more data become available, tralokinumab should be used with caution while nursing a newborn or preterm infant. Waiting for at least 2 weeks postpartum to resume therapy may minimize transfer to the infant.[4]
