Very Low Risk

Safe. Compatible. Minimal risk for breastfeeding and infant.

Sodium salt of citric acid.
It is used rectally in enemas as it acts as an osmotic laxative and in bladder irrigations to dissolve clots. It has the alkalizing properties of urine, neutralizing gastric pH and is an anticoagulant.

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

Given the small amounts and route of administration, systemic absorption is practically nil (AEMPS 2013), so no significant excretion in breast milk is expected.

If absorbed, it is metabolized to bicarbonate, which is compatible with breastfeeding.

Both sodium and bicarbonate are normal components of the body and are found in breastmilk at concentrations which are different to plasma (Allen 1991).
