What MIVACRON is used for

MIVACRON is used together with anaesthetic medicines to relax the body’s muscles. It will be given to you when you are asleep during surgery.

How does MIVACRON work?

Mivacurium chloride (the active ingredient in MIVACRON) belongs to a group of medicines called “neuromuscular blockers”.

MIVACRON works by blocking the effects of one of the body’s chemical messengers called acetylcholine. Acetylcholine is involved in muscle contraction.

Your doctor may, however, have prescribed MIVACRON for a different use to that described above.

If you have any questions about why you have been prescribed MIVACRON ask your doctor or pharmacist. Your doctor or pharmacist will be able to provide you with more information.

MIVACRON is not suitable for everyone.

Be sure that your doctor knows about the following before you are given MIVACRON:

  1. If you are allergic to:
  • mivacurium chloride (the active ingredient in MIVACRON).
  • any other ingredient listed at the end of this leaflet.
  1. If you are pregnant or breastfeeding.
  2. If you suffer from asthma or allergies.
  3. If you suffer from or have had heart, kidney or liver disease.
  4. If you, or a relative, have had previous difficulties with anaesthetics.
  5. If you are allergic to any other muscle relaxant medicine.
  6. If you are taking any other medication, including medicines that you buy without a prescription from a pharmacy, supermarket or health food shop.
    Your doctor or pharmacist will have a complete list of the medicines that may cause problems when taken with MIVACRON.

Make sure that your doctor is aware of any of the above before you are given MIVACRON.

When you must not use MIVACRON

MIVACRON should not be used after the expiry date printed on the pack. Your pharmacist will be able to tell what the expiry date is.


MIVACRON is a medicine which is given by injection and is administered by an experienced doctor or anaesthetist while you are asleep during surgery. The dosage will vary according to many factors such as body weight and existing conditions.

If you have any questions about the dose that you will receive you should ask your doctor or pharmacist.

In case of overdose

This is unlikely to happen because you will be under the care of a highly trained doctor or anaesthetist. Overdose leads to prolonged relaxation of the body’s muscles. This can be readily treated.

When to stop taking MIVACRON

MIVACRON is administered by an anaesthetist for certain surgical and other medical procedures. Therefore, MIVACRON is not taken on a regular basis.

Side effects

Tell your doctor or pharmacist as soon as possible if you do not feel well after you have received MIVACRON.

MIVACRON helps most people. In a few people it may have some unwanted side effects.

All medicines can have some side effects. Sometimes they are serious. Most of the time they are not.

  • skin flushing.
  • lowering of blood pressure.
  • tight breathing.
  • unwanted effects on the heart beat.
  • dizziness.
  • muscle spasms.

Ask your doctor or pharmacist to answer any questions you may have.

Other side effects not listed above may also occur in some people.


You do not have to keep MIVACRON as it is usually stored by the hospital pharmacist. MIVACRON should be protected from light and stored below 25°C but not frozen.
