1. What is Esmeron and what is it used for

Esmeron belongs to a group of medicines called muscle relaxants. Muscle relaxants are used in general anesthesia for surgical operations to relax the muscles completely. This makes the operation easier for the surgeon. Normally, nerves send messages to the muscles through impulses. Esmeron works by blocking these impulses, causing the muscles to relax. Since the muscles needed for breathing also relax, you will need help breathing (artificial respiration) during and after the operation until you can breathe on your own. The effect of the muscle relaxant is regularly monitored during the operation, and if necessary, more medication will be administered. The effects disappear at the end of the operation, and then you can start breathing on your own. Sometimes, another medication is given to speed up this process. Esmeron can also be used in the Intensive Care Unit to keep the muscles relaxed.

This medicine is for hospital use only.

2. What you need to know before you use Esmeron

Do not use Esmeron:

if you are allergic to rocuronium, bromide ions, or any of the other components of this medicine (listed in section 6).

Warnings and precautions

Your medical history may affect how Esmeron is administered to you.

Tell your anesthesiologist if you have had or currently have any of the following diseases:

allergy to muscle relaxants
kidney disease
heart disease
edema (fluid retention, for example, in the calves)
liver or bile duct disease, or liver function disorders
diseases that affect the nerves and muscles.

Also, inform your anesthesiologist if you have had:

a history of malignant hyperthermia (sudden fever with palpitations, rapid breathing, and muscle stiffness, pain, and/or weakness).

Certain medical conditions may affect how Esmeron works. For example, if you have any of these conditions, your anesthesiologist will take them into account when deciding the correct dose of Esmeron:

low potassium levels in the blood
high magnesium levels in the blood
low calcium levels in the blood
low protein levels in the blood
dehydration
too much acid in the blood
too much carbon dioxide in the blood
poor overall health
overweight
burns.

Children/elderly patients

Esmeron can be used in children and adolescents (from birth to 17 years) and elderly patients, but your anesthesiologist will evaluate your medical history first.

Using Esmeron with other medicines

Tell your doctor or pharmacist if you are using, have recently used, or might use any other medicines.

Other medicines may affect the effects of Esmeron or vice versa. If you take (or think you might take) any of the following medicines, you should inform your doctor.

The following medicines may increasethe effect of Esmeron:

certain anesthetics
prolonged use of corticosteroids with Esmeron for a long time in the Intensive Care Unit (anti-inflammatory medications)
certain medications for bacterial infections (antibiotics)
certain medications for bipolar disorder (such as lithium)
certain medications for heart disease or high blood pressure (quinidine, calcium antagonists, beta-blockers)
certain medications for malaria (quinine)
medications that increase urine production, such as diuretics
magnesium salts
local anesthetics (lidocaine, bupivacaine)
use of medications for epilepsy during an operation (phenytoin).

The following medicines may decreasethe effect of Esmeron:

prolonged use of medications for epilepsy: phenytoin and carbamazepine
medications for pancreatitis, blood coagulation disorders, or acute blood loss (protease inhibitors: gabexate, ulinastatin).

Pregnancy and breastfeeding

If you are pregnant or breastfeeding, think you might be pregnant, or plan to become pregnant, consult your doctor before Esmeron is administered to you.

Breastfeeding should be stopped 6 hours after the use of this medicine.

Driving and using machines

Your doctor will inform you when you can drive and use potentially hazardous machines safely after the administration of Esmeron.

Esmeron contains sodium

This medicine contains less than 23 mg of sodium (1 mmol) per vial; it is essentially "sodium-free".

3. How to use Esmeron

Your doctor will adjust the dose to your needs. You will be given Esmeron before or during the operation. The recommended dose is 0.6 mg per kilogram of body weight, and the effect lasts for 30 to 40 minutes. During the operation, the activity of Esmeron will be monitored. If necessary, you will be given more doses, which will depend on various factors, such as possible interactions with other medicines, the expected duration of the operation, your age, or your state of health.

Your doctor will administer Esmeron to you, either by intravenous injection or by continuous infusion.

If you use more Esmeron than you should

The medical staff will be monitoring the operation, and it is unlikely that you will be given too much Esmeron. However, if this happens, artificial respiration will be maintained until you are able to breathe on your own.

Your doctor may speed up your recovery by giving you a medication that counteracts the effects of the muscle relaxant.
