Aluminium Hydroxide

Very Low Risk for breastfeeding

Safe. Compatible.
Not risky for breastfeeding or infant.

Aluminum does not concentrate into breast milk.

After ingestion of antacids the Aluminum plasma levels increase from a basal-point of 7 μg/L to 55 μg/L at half-an-hour with a return to previous level 3 hours later.

Although a minimal amount of Aluminum may be found in the milk, there are not shown side-effects in the infant. Mother's milk has a mean concentration of 49 μg/L of Aluminum which is much lower than the amount of 180-700 μg/L found in artificial formulas.

Because of a low oral bioavailability the pass from the breast milk toward the infant's plasma is hampered, except in premature and newborn infants who may exhibit a higher intestinal absorption due to an increased permeability.

Avoid chronic or excessive use.

WHO Model List of Essential Medicines 2002: compatible with breastfeeding.


We do not have alternatives for Aluminium Hydroxide since it is relatively safe.

Suggestions made at e-lactancia are done by APILAM´s pediatricians and pharmacists, and are based on updated scientific publications.
It is not intended to replace the relationship you have with your doctor but to compound it.

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.
