Summary of Use during Lactation

No information is available on the clinical use of daclizumab during breastfeeding. Because daclizumab is a large protein molecule with a molecular weight of about 144,000 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. Until more data become available, daclizumab should be used with caution during breastfeeding, especially while nursing a newborn or preterm infant. Some authors recommend avoiding breastfeeding with daclizumab.[1,2]
