About this Medication

What the Medication is Used For

ZEMURON is one of a group of drugs called muscle relaxants for anesthesia. These drugs are used during an operation as part of the general anesthetic. When you have an operation your muscles may have to be completely relaxed. This makes it easier for the surgeon to perform the operation.

What it Does

ZEMURON blocks the nerve impulses to move your muscles. 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. At the end of surgery the effects of ZEMURON are allowed to wear off and you can start breathing on your own. Sometimes another drug is given to help speed this up.

When it Should not be Used

If you are hypersensitive (allergic) to rocuronium, the bromide ion or any of the other ingredients in ZEMURON.

What the Medicinal Ingredient Is

rocuronium bromide

What the Nonmedicinal Ingredients Are

Acetic acid, nitrogen, sodium acetate, sodium chloride, water for injections.

Each milliliter (mL) ZEMURON contains 1.72 mg sodium. No preservative has been added.

What Dosage Form it Comes In

ZEMURON is a colorless to slightly yellow/brown solution for injection or infusion containing 10 mg/mL rocuronium bromide. It is available in vials containing 50 mg (10 vials per pack) and 100 mg rocuronium bromide (10 vials per pack).

Not all pack sizes may be marketed.

Warnings and Precautions

Serious Warnings and Precautions

As for all drugs used during an operation, this drug should be administered only in a facility prepared to give resuscitation and life support by adequately trained health care professionals familiar with its actions, characteristics, and hazards.

Your medical history can influence the way that ZEMURON is given to you. Tell your doctor if you have now or have ever had any of the following:

  • an allergy to muscle relaxants
  • a decreased kidney function or kidney disease
  • a heart disease or heart valve disease
  • pulmonary hypertension
  • oedema (fluid retention for example at the ankles)
  • recent, severe vomiting, diarrhea, and “water pill” use
  • a liver or gallbladder disease or decreased liver function
  • diseases affecting nerves or muscles.

Tell your doctor if you have any other medical conditions, as they may influence how ZEMURON works.

Elderly / Children

ZEMURON can be used in children (from term newborns to adolescents) and elderly.

Pregnancy and Breast-Feeding

Tell your doctor if you are pregnant, or suspect that you are pregnant, or if you are breast-feeding.

Driving and Using Machines

Your doctor will inform you when it is safe to drive and operate potentially dangerous machinery after you have been administered ZEMURON.

Interactions With This Medication

Tell your doctor if you are taking or have recently taken any other medicines, including medicines obtained without a prescription. This will help your doctor to decide the correct dose of ZEMURON for you.

Proper Use of This Medication

Usual Dose

The doctor will determine the dose. You will be given ZEMURON before and/or during a surgical procedure. The usual dose is 0.6 mg rocuronium bromide per kg body weight and the effect lasts about 30 to 40 minutes. Your doctor may adjust the dose according to your need during the surgery.

Method and Route of Administration

ZEMURON is given by an adequately trained health care professional. It is not meant to be administered by yourself. ZEMURON is injected in a vein as a solution. It is administered as one single injection or continuous infusion.

Only an adequately trained health care professional may give ZEMURON.


As medical personnel will be monitoring your condition during the procedure it is unlikely that you will be given too much ZEMURON. However, if this happens artificial respiration will be continued until you are able to breathe again on your own. It is possible to counteract the effects of (too much) ZEMURON and speed-up your recovery by giving you a drug that reverses the effects of ZEMURON.
