Summary of Use during Lactation

Because it is a large protein molecule with a molecular weight of 3752 Da, the amount in milk is likely to be very low. Teduglutide is also poorly absorbed orally so absorption by a breastfed infant is unlikely. Two breastfed infants apparently experienced no adverse effects during maternal use of teduglutide, but no long-term data are available. Until more data are available, teduglutide should be used with careful infant monitoring during breastfeeding.

Effects in Breastfed Infants

One mother used teduglutide during pregnancy and postpartum while breastfeeding. She breastfed her infant (extent not stated) for 6 months. No mention was made of any adverse effects in the infant.[1]

A woman taking teduglutide because of removal of a portion of her gastrointestinal tract became pregnant and delivered a healthy infant. She breastfed her infant and the drug was restarted 1 month after delivery. She breastfed (extent not stated) her infant for another 4 months during treatment. The infant experienced no side effects during breastfeeding.[2]
