Likely Compatibility

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

It is composed by bisphosphonates.

Most bisphosphonates are acidic compounds that achieve low plasma concentration. Both features make it unlikely excretion into the milk in clinically significant amount.

Intestinal absorption of bisphosphonates is very low even during fasting and is considered negligible in the presence of milk due to formation with the calcium of non absorbable compounds.

A latest update no published data were found on excretion in the breast milk.

Until more data about this drug regarding breastfeeding is available, safer known alternatives (pamidronate) should be of choice, especially in the neonatal period and in case of prematurity.


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.
