Is Lanreotide safe while breastfeeding?
Here is what LactMed, the Drugs and Lactation Database published by the U.S. National Institute of Child Health and Human Development (NICHD), reports about Lanreotide. The text below is quoted from that source — it is not our own verdict.
Summary of use during breastfeeding
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.
Effects on the breastfed infant
Two women with acromegaly received lanreotide 30 mg every 28 days and successfully breastfed, one for 1.5 months and the second for 3 months.[2]
A woman with acromegaly was treated with lanreotide Autogel 120 mg monthly, cabergoline 2 mg weekly and pegvisomant 80 mg weekly. She breastfed (extent not stated) her infant and they were followed for 12 years. Her child had normal growth and development.[3]
