Summary of Use during Lactation

No information is available on the clinical use of teclistamab during breastfeeding. Because teclistamab is a large protein molecule with a molecular weight of 146,000 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. The manufacturer recommends that breastfeeding be withheld during therapy and for 5 months after the last dose.
