Likely Compatibility

Fairly safe. Mild or unlikely adverse effects. Compatible under certain circumstances. Follow-up recommended. Read Commentary.

Glycerin or glycerol is a normal component of human tissues. Involved in lipid and galactose synthesis which is metabolized to glucose or glycogen.
It is found naturally in breast milk, with a highest concentration in colostrum.

When it is used rectally as a laxative, has little or no absorption. It has been used in preterm infants.

The oral or intravenous administration is rarely used (extracellular edema, intracranial hypertension, diagnosis of Meniere's disease). A short half-life span makes it compatible with breastfeeding in these rare cases.
It also compatible with intraocular administration.

It has been used in creams and gels to treat pain and cracks of nipple during lactation without clear results on effectiveness. In those cases it should be cleaned thoroughly with water before the next breast suckling to prevent it could be swallowed by the infant, since a high intestinal absorption may induce an increased plasma osmolality that can result in dehydration of the infant.


We do not have alternatives for グリセリン.

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.
