1. Why am I using Rocuronium Bromide?

Rocuronium Bromide contains the active ingredient rocuronium bromide. Rocuronium Bromide is one of a group of medicines called muscle relaxants.

Rocuronium Bromide is used during an operation as part of the general anaesthetic. When you have an operation, your muscles must be completely relaxed. This makes it easier for the surgeon to perform the operation.

Normally the nerves send messages to the muscles by impulses. Rocuronium bromide acts by blocking these impulses so the muscles are relaxed. Because the muscles needed for breathing also become relaxed you will need help with your breathing (artificial respiration) during and after your operation until you can breathe on your own. During the operation the effect of the muscle relaxant is constantly checked and if necessary some more drug is given. At the end of the operation the effects of Rocuronium bromide are allowed to wear off and you can start breathing on your own. Sometimes another drug is given to help speed this up. Rocuronium bromide can also be used in Intensive Care to keep your muscles relaxed.

Ask your doctor if you want any more information about this medicine.

Rocuronium bromide is not addictive.

4. How do I use Rocuronium Bromide?

How much to take / use

  • The doctor will determine the dose. The usual dose is 0.6 mg rocuronium bromide per kg body weight and the effect lasts 30-40 minutes. During the operation your doctor will check whether Rocuronium Bromide is still working. You may be given additional doses if they are needed.

When to take / use Rocuronium Bromide

  • Rocuronium Bromide will be given by a doctor. It will not be given to you until you are asleep from the anaesthetic.
  • It will be injected into a vein before and/or during an operation. It will be given as a single injection or continuous infusion

If you use too much Rocuronium Bromide

As Rocuronium bromide doses are carefully worked out and are given by a doctor experienced in its use, it is extremely unlikely that you will be given too much Rocuronium bromide. However, if this does happen, your doctor will make sure that you continue breathing artificially until you can breathe on your own again. Your doctor may speed-up your recovery by giving you a drug that reverses the effects of Rocuronium bromide.
