What DBL Rocuronium Bromide Injection is used for

Rocuronium is one of a group of medicines called muscle relaxants.
Muscle relaxants are 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 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 breath 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 the medicine are allowed to wear off and you can start breathing on your own. Sometimes another drug is given to help speed this up.
Rocuronium can also be used in intensive care to keep your muscles relaxed.
Ask your doctor if you want any more information about this medicine.
DBL Rocuronium Bromide Injection is not addictive.

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

If you take too much (overdose)

As DBL Rocuronium Bromide Injection 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.
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.
In case of overdose, immediately contact the Poisons Information Centre for advice (telephone 13 11 26 in Australia).
