Is Idusulfase Safe in Breastfeeding

I am a breastfeeding mother and i want to know if it is safe to use Idusulfase? Is Idusulfase safe for nursing mother and child? Does Idusulfase extracts into breast milk? Does Idusulfase has any long term or short term side effects on infants? Can Idusulfase influence milk supply or can Idusulfase decrease milk supply in lactating mothers?

No information is available on the clinical use of Idusulfase during breastfeeding. Because it is a large protein molecule with a molecular weight of about 76,000, 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.
