Summary of Use during Lactation

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.
