Question

I am a breastfeeding mother and i want to know if it is safe to use Liraglutide? Is Liraglutide safe for nursing mother and child? Does Liraglutide extracts into breast milk? Does Liraglutide has any long term or short term side effects on infants? Can Liraglutide influence milk supply or can Liraglutide decrease milk supply in lactating mothers?

Liraglutide lactation summary

Liraglutide usage has low risk in breastfeeding
  • DrLact safety Score for Liraglutide is 3 out of 8 which is considered Low Risk as per our analyses.
  • A safety Score of 3 indicates that usage of Liraglutide may cause some minor side effects in breastfed baby.
  • Our study of different scientific research indicates that Liraglutide may cause moderate to no side effects in lactating mother.
  • Most of scientific studies and research papers declaring usage of Liraglutide low risk in breastfeeding are based on normal dosage and may not hold true for higher dosage.
  • While using Liraglutide We suggest monitoring child for possible reactions. It is also important to understand that side effects vary largely based on age of breastfed child and time of medication in addition to dosage.
  • Score calculated using the DrLact safety Version 1.2 model, this score ranges from 0 to 8 and measures overall safety of drug in lactation. Scores are primarily calculated using publicly available case studies, research papers, other scientific journals and publically available data.

Answer by Dr. Ru: About Liraglutide usage in lactation

Glucagon-like peptide 1 analogue that stimulates endogenous insulin secretion. Used to treat obesity and type 2 diabetes in combination with other oral antidiabetics, especially metformin. Administered subcutaneously. The most common side effects are nausea, vomiting and diarrhea. Low risk of hypoglycemia in monotherapy. Since the last update we have not found published data on its excretion in breast milk. Its pharmacokinetic data (high molecular weight and high percentage of plasma protein binding) make it very unlikely that significant amounts will pass into breast milk (Serrano 2014). Due to its protein nature, it deteriorates in the gastrointestinal tract, not being absorbed (Serrano 2014). This low oral bioavailability would make it difficult for it to pass to the infant’s plasma ingesting breast milk, except in preterm infants and in the immediate neonatal period when there may be increased intestinal permeability. Diet, exercise, and breastfeeding improve blood sugar levels.

No information is available on the clinical use of liraglutide during breastfeeding. Because liraglutide is a large peptide molecule with a molecular weight of 3751 daltons, the amount in milk is likely to be very low and absorption is unlikely because it is probably destroyed in the infant's gastrointestinal tract. Until more data become available, liraglutide should be used with caution during breastfeeding, especially while nursing a newborn or preterm infant.
