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.
