Drug Levels and Effects
Summary of Use during Lactation
No information is available on the clinical use of idursulfase during breastfeeding. Because it is a large protein molecule with a molecular weight of about 76,000 Da, the amount in milk is likely to be very low and absorption is unlikely because it is probably destroyed in the infant's gastrointestinal tract. If idursulfase is required by the mother, it is not a reason to discontinue breastfeeding. Until more data are available, idursulfase should be used with infant careful monitoring during breastfeeding.
