Drug Levels and Effects:

Summary of Use during Lactation:

Amisulpride is not approved for marketing in the United States by the US Food and Drug Administration, but is available in other countries. Because there is little published experience with amisulpride during breastfeeding and excretion into breastmilk is higher than with other pharmacologically similar drugs, an alternate drug may be preferred, especially while nursing a newborn or preterm infant.

Drug Levels:

Maternal Levels.

A nursing mother was taking oral amisulpride 100 mg twice daily at 8:00 am and 12:30 pm, and desvenlafaxine 250 mg daily. Eight breastmilk samples were obtained over a 24-hour period with a breast pump. The average breastmilk concentration was 1.2 mg/L which equated to an infant dose of 183 mcg/kg daily or 6.1% of the maternal weight-adjusted dosage.[1]

A woman who was 13 months postpartum had been taking amisulpride 400 mg (5 mg/kg) once daily for 9 days. Eight milk samples were obtained over a 24-hour period and consisted of about 50% foremilk and 50% hindmilk. The average breastmilk concentration was 1.6 mg/L which would provide a fully breastfed infant a dose of 534 mcg/kg daily or 10.7% of the maternal weight-adjusted dosage.[2]

Infant Levels.

A nursing mother had been taking oral amisulpiride 100 mg twice daily at 8:00 am and 12:30 pm, and desvenlafaxine 250 mg daily for 12.6 weeks. Her partially breastfed infant was 5 months old. The infant's serum amisulpride concentration 3.1 hours after the mother's daily dose was 4 mcg/L or 3.9% of the maternal serum concentration.[1]

Effects in Breastfed Infants:

A 13-month-old infant was partially breastfed by a mother who was taking amisulpride 400 mg, fluvoxamine 200 mg, andazathioprine150 mg daily, and was using nicotine chewing gum for smoking cessation. The mother had been taking amisulpride for 9 days; the duration of the other medications was not stated. A pediatric examination found the infant to be developing well.[2]

Possible Effects on Lactation:

Amisulpride increases serum prolactin[3][4][5][6][7] and has caused galactorrhea in at least 2 women.[6][7] The prolactin level in a mother with established lactation may not affect her ability to breastfeed.
