ADAMTS13 is a synthetic form of a natural protein in the body. No information is available on the use of ADAMTS13 during breastfeeding. Because ADAMTS13 is a large protein molecule with a molecular weight of 172,000 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] Waiting for at least 2 weeks postpartum to resume therapy may minimize transfer to the infant.[3] It is acceptable to use in nursing mothers.
