Lactitol monohydrate

Very Low Risk

Safe. Compatible. Minimal risk for breastfeeding and infant.

Synthetic derivative of lactulose. It is a disaccharide analogue of lactulose with similar action and uses.
It does not hydrolyze in the intestine, so it is not absorbed, reaching the colon intact, where it exerts its function as an osmotic laxative (AEMPS 2015, Würsch 1989, Metzger 1988). Indicated in constipation and hepatic encephalopathy.
Oral administration in a daily dose.

Since the last update we have not found published data on its excretion in breastmilk.

Its virtually zero oral bioavailability makes plasma levels null and therefore does not transfer to breastmilk (AEMPS 2015, P-RMS 2010).

For the same reason, it impedes transfer from breastmilk to infant plasma.

We do not have alternatives for Lactitol monohydrate since it is relatively safe.

Suggestions made at e-lactancia are done by APILAM team of health professionals, and are based on updated scientific publications. It is not intended to replace the relationship you have with your doctor but to compound it. The pharmaceutical industry contraindicates breastfeeding, mistakenly and without scientific reasons, in most of the drug data sheets.

Jose Maria Paricio, Founder & President of APILAM/e-Lactancia

Your contribution is essential for this service to continue to exist. We need the generosity of people like you who believe in the benefits of breastfeeding.

Thank you for helping to protect and promote breastfeeding.
