Very Low Risk for breastfeeding

Safe. Compatible.
Minimal risk for breastfeeding and infant.

It is a non-depolarizing muscle relaxant drug with a peripheral action that is used as premedication for endotracheal intubation, general anesthesia and mechanical ventilation.

At latest update, no relevant published data concerning excretion into breast milk were found.

Because a relatively high molecular-weight and a high protein-binding capacity, excretion into breast milk is thought to be low.

In addition, it has a low oral bioavailability which means that absorption from the breast milk ingested may be low.

Atracurium should not prevent a mother from breast feeding her baby shortly after recovering from an anesthesia if she is in good condition.


We do not have alternatives for Atracurium 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.

Thank you for helping to protect and promote breastfeeding.
