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.

A high molecular weight may decrease excretion into breast milk as well as a rapid elimination time.

In addition, a low oral bioavailability makes unlikely a pass from ingested mother's milk onto the infant's plasma.

Mivacurio 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 Mivacurium 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.
