Can you take lanreotide while breastfeeding?
What LactMed says
The National Library of Medicine’s own summary, quoted in full. We do not write a verdict of our own on this question, and we do not compress theirs into a label.
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. The manufacturer states that women should not breastfeed during treatment with depot lanreotide and for 6 months following the last dose.

Frequently asked questions
Can you take lanreotide while breastfeeding?
The excretion of lanreotide into breastmilk has not been studied. The full record is quoted on this page, and the decision is one to make with the person who prescribed it — LactMed itself states it is not a substitute for professional judgement.
What can I take instead of lanreotide while breastfeeding?
LactMed lists Octreotide as alternate drugs to consider. That is the database's own list for this drug — whether any of them suits you depends on what you are treating.
Does lanreotide pass into breastmilk?
LactMed's measured drug levels for lanreotide are quoted in full on this page, under "How much gets into breastmilk".
Do I need to pump and dump after taking lanreotide?
LactMed does not frame its records that way — it reports measured drug levels in milk and what has been observed in breastfed infants, which is what this page quotes. "Pump and dump" advice for a specific drug and dose should come from your clinician or a pharmacist, not from a general rule.
