Suxamethonium Chloride

Very Low Risk for breastfeeding

Safe. Compatible.
Minimal risk for breastfeeding and infant.

Muscle-relaxant agent with a peripheric depolarizing action that is used for rapid endotracheal intubation procedures, which also has a transient effect.

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 1 minute), a significant excretion into breast milk is unlikely.

Also, a low oral bioavailability renders the pass of this agent to the infant's plasma, highly unlikely.

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

List of Medicines (WHO-2002): compatible with Breastfeeding.


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