Barium Sulphate

Very Low Risk

Safe. Compatible. Minimal risk for breastfeeding and infant.

Barium sulfate is a radiographic contrast agent used in X-ray examination of the gastrointestinal tract by computed tomography (CT scan).

At the time of the last update, we found no published data on its excretion in breast milk.

Barium sulfate is not absorbed after oral or rectal administration nor is it metabolized in the body, so it cannot be excreted in breast milk or reach the infant.

After radiographic examination with barium sulfate no interruption of lactation is necessary.

Recommendations for Drugs in the Eleventh WHO Model List of Essential Drugs: compatible with Breastfeeding. (WHO 2002)


We do not have alternatives for Barium Sulphate 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.

José María Paricio, founder of e-lactancia.
