1. What Anectine is and what it is used for

Anectine contains a medicine called suxamethonium chloride. This belongs to a group of medicines called muscle relaxants.

Anectine is used:

  • to relax muscles during operations on adults and children
  • to help insert a tube into the windpipe (endotracheal intubation), if a person needs help to breathe
  • to reduce how strongly your muscles contract

Ask your doctor if you would like more explanation about this medicine.

2. What you need to know before you are given Anectine

You should not be given Anectine if:

  • you are allergic to suxamethonium chloride, any other muscle relaxants or any of the other ingredients of Anectine Injection (listed in section 6)
  • you or your family have reacted badly to an anaesthetic before such as a very high body temperature (malignant hyperthermia)
  • you have an inherited enzyme abnormality, pseudocholinesterase which breaks down suxamethonium in the body
  • you have had a major accident, operation or severe burns within the last three months
  • you have not been able to move for a long time such as to allow a broken bone to mend or a long period of bed rest
  • you have high levels of potassium in your blood (hyperkalaemia)
  • you have recently had an eye injury
  • you suffer from a problem caused by too much pressure in your eye called ‘glaucoma’
  • you or any of your family have a disease of the muscles or nerves, such as a muscle wasting disease, paralysis, motor neurone disease, muscular dystrophy or cerebral palsy.

If any of the above apply to you or if you are not sure, talk to your doctor, nurse or member of the operating theatre staff before you are given Anectine.
