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.
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.

It is the binding of the monoclonal antibody trastuzumab conjugated to emtansine, a highly cytotoxic agent, which is selectively transported by trastuzumab to cancer cells expressing the HER2 gene. Indicated for the treatment of unresectable or metastatic HER2-positive locally advanced HER2-positive breast cancer who have previously received trastuzumab and a taxane separately or in combination. Intravenous administration in a 1-3 week schedule.
At the date of the last update, we found no published data on its excretion in breast milk.
Although trastuzumab, due to its very high molecular weight and lack of intestinal absorption, could be compatible with breastfeeding, emtansine (there is an average of 3.5 molecules of emtansine for every molecule of trastuzumab) is of low molecular weight (LactMed) and could be excreted in breast milk.
