It should be used with caution in patients with bone fractures, cardiac or respiratory disease. Dose of neuromuscular blocking agent need to be clearly titrated for individual patients according to their response; monitoring of the degree of block is recommended in order to reduce the risk of overdosage. Patients who have received neuromuscular blocker should always have their respiration assisted or controlled until the drug has been inactivated or antagonized.
