Section 4.4 - Warning relating to cross-sensitivity strengthened as below:
High rates of cross-sensitivity (greater than 50%) between neuromuscular blocking agents have been reported.  Therefore, where possible, before administering suxamethonium, hypersensitivity to other neuromuscular blocking agents should be excluded.  Suxamethonium, should only be used when absolutely essential in susceptible patients.  Patients who experience a hypersensitivity reaction under general anaesthesia should be tested subsequently for hypersensitivity to other neuromuscular blockers.

Section 4.7 - Effects on Ability to Drive and Use Machines amended as below:
This precaution is not relevant to the use of suxamethonium injection. Suxamethonium will always be used in combination with a general anaesthetic and therefore the usual precautions relating to performance of tasks following general anaesthesia apply.

Section 4.3 - The last paragraph of this section has been updated to read:

"Anectine should

not be usedavoided in patients with skeletal muscle myopathies, e.g. Duchenne muscular dystrophy since its administration may be associated with rigidity, malignant hyperthermia, ventricular dysrhythmias and cardiac arrest secondary to acute rhabdomyolysis with hyperkalaemia, myoglobinaemia, cardiac arrest, and post-operative respiratory depression."

Section 4.4 - The fifth paragraph from the end of this section has been updated to read:

 

"Caution should be exercised when using suxamethonium in children, since paediatric patients are more likely to have an undiagnosed myopathy or an unknown predisposition to malignant hyperthermia

and rhabdomyolysis, which places them at increased risk of serious adverse events following suxamethonium (see section 4.3 Contraindications and section 4.8 Adverse Reactions)."
