Summary of Use during Lactation

No information is available on the clinical use of secukinumab during breastfeeding. Because secukinumab is a large protein molecule with a molecular weight of 151,000 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.[1-3] Some professional guidelines consider secukinumab to be acceptable during breastfeeding.[4] Until more data become available, secukinumab 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.[5]
