Mivacurium Chloride


Safe substance and/or breastfeeding is the best option.

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. Intravenous administración

Since the last update we have not found published data on its excretion in breastmilk.

Its moderately elevated molecular weight and very rapid half-life elimination period (under 2 minutes) make it highly unlikely that significant quantities will pass into breast milk. (Dalal 2014, Spigset 1994)

Also, quaternary ammonium muscle relaxants are poorly absorbed from the gastro-intestinal tract; its low oral bioavailability renders the pass of this agent to the infant's plasma highly unlikely. (Spigset 1994)

Mivacurium does not prevent a mother from breast feeding her baby shortly after recovering from anesthesia if she is awake and in good condition.


We do not have alternatives for Mivacurium Chloride since it is relatively safe.

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.
