Succinylcholine Chloride

Very Low Risk

Safe. Compatible. Minimal risk for breastfeeding and infant.

Succinylcholine or Suxamethonium is a muscle-relaxant agent with a peripheric depolarizing action that is used for rapid endotracheal intubation procedures, mechanical ventilation, and surgical procedures. Intravenous administration.

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

Because of a very rapid half-life elimination period, less than one minute (Kato 1999, Torda 1997, Hoshi 1993), a significant excretion into breast milk is unlikely. (Dalal 2014, Spigset 1994)

Also, its low oral bioavailability renders the pass of this agent to the infant's plasma highly unlikely. (Spigset 1994)

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

Experts authors consider the use of this medication to be probably compatible during breastfeeding (Briggs 2015, Dalal 2014, Howie 2006). Recommendations for Drugs in the Eleventh WHO Model List of Essential Drugs: compatible with Breastfeeding. (WHO 2002)


We do not have alternatives for Succinylcholine 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.

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.
