Drug Levels and Effects

Summary of Use during Lactation

No information is available on the clinical use of dornase alpha (hamster) during breastfeeding. Because it is a large protein molecule with a molecular weight of about 37,000, 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. A task force respiratory experts from Europe, Australia and New Zealand found that dornase alfa is compatible with breastfeeding.[1]
