For additional information and enrollment: pomperegistry.com In 1 woman, alglucosidase alfa activity was evident in breast milk for only 24 hours after a dose. At 3 and 77 days of age, anti-alglucosidase alfa antibodies were negligible in the serum of an infant born to a mother receiving alglucosidase alfa 20 mg/kg IV every 2 weeks during pregnancy and lactation. This infant was examined regularly up to 1 year of age and showed normal development; extent of breastfeeding was not reported.

LactMed: As a precaution, breastfeeding should be withheld for 24 hours after each dose. -AU: Use is recommended only if clearly needed and after careful benefit/risk analysis for mother and child. -UK: Breastfeeding should be stopped when this drug is used. -US: Caution is recommended; to minimize infant exposure, the nursing mother may pump and discard breast milk produced during the 24 hours after drug administration. Excreted into human milk: Yes Comments: -The effects in the nursing infant are unknown. -This drug is a large protein molecule (molecular weight about 110,000); the amount in milk is likely to be very low; absorption unlikely as it is probably destroyed in the infant gastrointestinal tract.
