Dibasic/Monobasic/tribasic Sodium Phosphate

Very Low Risk

Safe. Compatible. Minimal risk for breastfeeding and infant.

Phosphates are used as a laxative and to clean the bowel before medical examinations. They base their action on the little or zero amount which is absorbed (Nice 2000), causing water to escape from the intestine and severe diarrhea.

Since the last update, we have not found published data on its excretion in breast milk.

Both sodium and phosphate are normal components of the body and are found in breast milk at concentrations different to plasma. (Allen 1991)

Temporary increases in plasma phosphate levels have been observed after the administration of sodium phosphate enema (Salix 2009, Ehrenpreis 2009). It is not known whether this may affect the concentration of phosphate in breast milk, but it is believed that the variation is minimal, temporary and does not have clinical repercussions in the infant.

Take into account the loss of liquids to drink as much as needed and avoid dehydration of the nursing mother who is already producing about 1 litre of liquid in the form of milk a day.

Expert authors consider phosphate-based laxatives compatible with breastfeeding. (Nice 2000)

A nursing mother reported to us in 2022 that her 16-month-old infant had two profuse but self-limiting liquid stools in the 24 hours after she had taken a dibasic/monobasic phosphate preparation as a preoperative preparation.

Alternatives

We do not have alternatives for Dibasic/Monobasic/tribasic Sodium Phosphate 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.
