Lanreotide During Pregnancy

Category N/ANote that the FDA has deprecated the use of pregnancy categories, so for some medications, this information isn’t available. We still think it’s useful to list historical info, however, given what a common proxy this has been in the past.

Taking Lanreotide While Breastfeeding
What are recommendations for lactation if you're taking Lanreotide?
The excretion of lanreotide into breastmilk has not been studied. However, because it has a high molecular weight of 1096 daltons it is likely to be poorly excreted into breastmilk and it is a peptide that is likely digested in the infant’s gastrointestinal tract, so it is unlikely to reach the clinically important levels in infant serum. Lanreotide has been given by injection to newborn infants with congenital hyperinsulinemia; reversible mild elevation of liver enzymes occurred in some infants.[1] The manufacturer states that women should not breastfeed during treatment with depot lanreotide and for 6 months following the last dose.
