Answer by Dr. Ru: About Linaclotide usage in lactation

A 14-amino acid synthetic peptide related to the endogenous guanylin peptide family.Administered in moderate-severe constipation from irritable bowel syndrome and in idiopathic chronic constipation. It acts locally in the intestine, without being absorbed (EMA 2016). It is metabolized in the intestine obtaining its main active metabolite, des-tyrosine. Both linaclotide and des-tyrosine are digested by intestinal enzymes and transformed into natural amino acids. Since the last update we have not found any published data on its excretion in breast milk. Its pharmacokinetic data (zero or negligible intestinal absorption with undetectable plasma levels and high molecular weight) make it very unlikely that significant amounts will pass to breast milk (EMA 2016).

Answer by DrLact: About Linaclotide usage in lactation

Linaclotide is minimally absorbed from the gastrointestinal tract and the drug and its active metabolite is not measurable in plasma following administration of recommended doses. Linaclotide would not be expected to cause any adverse effects in breastfed infants. If linaclotide is required by the mother, it is not a reason to discontinue breastfeeding.
