Can I take Mepolizumab while breastfeeding?

No information is available on the clinical use of mepolizumab during breastfeeding. Because it is a large protein molecule with a molecular weight of about 149,000, 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.
