Excreted into human milk: Unknown
Excreted into animal milk: Unknown

Comments:
-There are no data on the effects of this drug on the breastfed infant or its effects on milk production.

Because this drug is a large protein molecule, the amount in milk is likely very low and absorption is unlikely because it is probably destroyed in the infant's gastrointestinal tract. The developmental and health benefits of breastfeeding should be considered along with the mother's clinical need for this drug and any potential adverse effects to the breastfed infant from the drug or from the underlying maternal condition. Nursing mothers are encouraged to register themselves in the Fabry registry; for additional information see www.registrynxt.com
