What Esmeron is used for

Esmeron 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. Esmeron 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 Esmeron are allowed to wear off and you can start breathing on your own. Sometimes another drug is given to help speed this up. Esmeron can also be used in Intensive Care to keep your muscles relaxed.

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

Esmeron is not addictive.

Before you are given Esmeron

When you must not be given it

You must not be given Esmeron if you have an allergy to:

  • any medicine containing rocuronium bromide
  • any of the ingredients listed at the end of this leaflet

Some of the symptoms of an allergic reaction may include shortness of breath, wheezing or difficulty breathing; swelling of the face, lips, tongue or other parts of the body; rash, itching or hives on the skin.

Esmeron should not be given to a child under the age of one month. The safety of administration of Esmeron has not been established in children under the age of one month.

Before you are given it

If you are going to have an operation it is important that you discuss the following points with your doctor, since it can influence the way Esmeron is given to you.

Tell your doctor if you have or have had any medical conditions, especially the following:

  • an allergy to muscle relaxants
  • kidney disease
  • liver or gallbladder disease
  • a heart disease
  • diseases affecting nerves or muscles
  • oedema (local or generalised swelling due to fluid)

Certain medical conditions may affect how Esmeron works.

  • low potassium levels in the blood
  • high magnesium levels in the blood
  • low calcium levels in the blood
  • low levels of protein in the blood
  • dehydration
  • too much acid in the blood
  • too much carbon dioxide in the blood
  • general ill-health
  • overweight
  • burns

If you are suffering from any of these conditions your doctor will take this into account when deciding the correct dose of Esmeron for you.

Esmeron can be used in children (30 days to adolescence) and elderly but your doctor should first assess your medical history.

Elderly (65 years and older) may be at an increased risk of residual paralysis.

Tell your doctor if you have allergies to any other medicines, foods, preservatives or dyes.

Tell your doctor if you are pregnant or plan to become pregnant or are breast-feeding. Your doctor will discuss the risks and benefits of using Esmeron if you are pregnant or breast-feeding.

If you have not told your doctor about any of the above, tell them before you are given Esmeron.

Taking other medicines

Tell your doctor if you are taking any other medicines, including any that you get without a prescription from your pharmacy, supermarket or health food shop.

Some medicines may be affected by Esmeron, or affect how well it works. These include:

  • anaesthetics, medicines to make you sleep during surgery
  • long term concurrent use of corticosteroids (anti-inflammatory medicines) and Esmeron in the Intensive Care Unit
  • antibiotics
  • lithium, a medicine used to treat bipolar disorder
  • medicines used to treat heart disease or high blood pressure (quinidine, calcium channel blockers, beta-blockers and diuretics (fluid tablets))
  • quinine, a medicine used to treat malaria
  • magnesium salts
  • lignocaine and bupivacaine (local anaesthetics)
  • other muscle relaxants
  • carbamazepine and phenytoin, medicines used to treat epilepsy

You may need to use different amounts of your medicines or take different medicines. Your doctor will advise you.

If you are taking magnesium sulphate to treat toxaemia of pregnancy (preeclampsia), tell your doctor as the dose of Esmeron may need to be reduced.

Your doctor will have a complete list of medicines that may cause problems when used with Esmeron.

How Esmeron is given

Esmeron 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.

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 Esmeron is still working. You may be given additional doses if they are needed.

Overdose

As Esmeron 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 Esmeron. 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 Esmeron.

After having Esmeron

Things to be careful of

Your doctor will tell you when it is safe to drive and operate potentially dangerous machinery after you have been given Esmeron.
