In common with all neuromuscular-blocking agents, Atracurium besylate should be used during pregnancy only if the potential benefit to the mother outweighs any potential risk to the foetus.
Atracurium besylate is suitable for maintenance of muscle relaxation during caesarean section as it does not cross the placenta in clinically significant amounts following recommended doses.
It is not known whether Atracurium besylate is excreted in human milk.
