1. What Magnevist is and what it is used for
Magnevist is used together with a technique called Magnetic Resonance Imaging
(MRI) to create artificial contrast or enhancement to help make an MRI scan of the
area of your body that your doctor wants to investigate clearer.
MRI is a modern scanning technique which produces very high quality pictures of
various parts of your body without using X-rays. The use of MRI can provide a quick,
early and accurate diagnosis.
The scanner uses a strong magnetic field and radiowaves to measure the magnetic
properties of body tissues. Using a computer, this information is converted into a
black and white picture which can help your doctor see and investigate the
differences between normal and abnormal tissue.
Sometimes MRI is used in areas where it cannot produce a clear black and white
picture. This is when Magnevist is used. Magnevist produces a clearer image and
allows the doctor to see the area of interest better. Sometimes several scans will be
taken before Magnevist is injected and then further scans taken after the injection.
This medicine is for diagnostic use only.
2. Before you are given Magnevist
Do not use Magnevist if:
you are, or suspect you are allergic (hypersensitive) to any of the ingredients
of Magnevist (see Section 6: Further Information)
you suffer from severe kidney problems, or if you are a patient who is about
to have or has recently had a liver transplant,,as use of Magnevist in
patients with these conditions has been associated with a disease called
Nephrogenic Systemic Fibrosis (NSF). NSF is a disease involving thickening
of the skin and connective tissues. NSF may result in severe joint immobility,
muscle weakness or may affect the normal working of internal organs which
may potentially be life threatening
you have a heart pacemaker or if there are any implants or clips containing
iron inside your body. (This is not because of an interaction with Magnevist
but because if you have any of these, you should not be placed in a strong
the patient is a newborn baby up to 4 weeks of age.
Take special care with Magnevist
Your doctor will need to take special care when giving you Magnevist if:
you have a history of allergy (e.g. hay fever, hives), asthma, or have had a
reaction to another type of contrast media. This is because you may be more
likely to have an allergic reaction
you suffer from heart or blood circulation problems. This is because in the
rare event that you have an allergic reaction, it is more likely to be serious or
you have epilepsy or have ever had fits, seizures or a mass in or around your
brain. Fits or seizures have occurred rarely in patients with similar conditions.
Tell the radiographer or MRI-centre staff so that they will be prepared to deal
with any problems that occur
your kidneys do not work properly. Magnevist should only be given after
careful consideration if you have kidney problems
you have recently had, or soon expect to have, a liver transplant
the patient is an infant under 1 year of age. As kidney function is immature in
infants up to 1 year of age, Magnevist will only be used in infants after careful
consideration by the doctor.
Before you receive Magnevist, you must tell the radiographer or MRI-centre staff if
any of these apply to you. You will also need to have a blood test to check how well
your kidneys are working.
If you have any blood tests after your MRI scan, tell your doctor you have been
given Magnevist. This is because some tests for iron levels in the blood may be
affected for up to 24 hours after Magnevist has been given.
Taking or using other medicines
Please tell the radiologist or MRI-centre staff if you are taking or have recently taken
any other medicines, including medicines obtained without prescription. This is
particularly important if you are taking:
beta blockers (drugs used to treat heart problems or blood pressure). This is
because in the rare event that you have an allergic reaction, you may need to
be given different medicines than normal to treat the reaction.
Using with food and drink
MRI contrast media like Magnevist can make you feel sick or actually be sick.
Therefore, you may be asked not to eat anything for 2 hours before the examination.
Pregnancy and breast-feeding
Ask your doctor for advice before taking any medicine.
You must tell your doctor if you think you are or might become pregnant as
Magnevist should not be used during pregnancy unless strictly necessary.
Tell your doctor if you are breast-feeding or about to start breast-feeding. Breastfeeding should be discontinued for at least 24 hours after you receive Magnevist.
3. How you will be given Magnevist
You will be asked to lie down on the MRI scanning bed and then Magnevist will be
injected into a vein. The MRI staff will observe you for at least 30 minutes after the
injection just in case you have any side effects.
The dose of Magnevist varies depending on your weight and how much the image of
the area needs to be made clearer. Typically 0.2ml Magnevist per kilogram body
weight is used, but this may be increased in adults to 0.4ml or even 0.6ml per
kilogram body weight and in children (over 2 years) to 0.4ml per kilogram body
weight. The doctor will decide how much Magnevist is needed for your investigation.
Scanning may start immediately after Magnevist injection but may take place later
depending on your examination (usually up to 45 minutes).
You should not be given Magnevist if you suffer from severe kidney problems or if
you are a patient who is about to have or has recently had a liver transplant.
Magnevist should also not be used in newborn babies up to the age of 4 weeks.
If you have moderate kidney problems, you should only receive one dose of
Magnevist during a scan and you should not receive a second injection for at least 7
As kidney function is immature in infants up to 1 year of age, infants should only
receive one dose of Magnevist during a scan and should not receive a second
injection for at least 7 days.
It is not necessary to adjust your dose if you are 65 years of age or older but you will
have a blood test to check how well your kidneys are working.
If you receive more Magnevist than you should
Overdosing is unlikely. If it does happen the doctor will treat any symptoms that
follow and may need to use a kidney dialysis machine to remove Magnevist. There
is no evidence to suggest that this will prevent the development of NSF (see section
4 Possible side effects) and should not be used as treatment for the condition.
4. Possible side effects
Like all medicines, Magnevist can cause side effects, although not everybody gets
Side effects you may get after being given a contrast medium like Magnevist are
usually mild to moderate and do not last long.
However, as with similar contrast media, severe and life-threatening reactions, as
well as deaths, have been reported.
If you notice:
• itching of the skin, rash, wheals on the skin (urticaria)
• difficulty breathing, gagging, feeling of suffocation
• swelling of the face, neck or body

• headache, dizziness, feeling faint
• feeling particularly hot or cold, sweating
• paleness or reddening of the skin
• chest pain, cramp, tremor
• feeling sick
Tell the radiologist or MRI staff immediately as these may be the first signs of
allergic reaction or shock. Your investigation will need to be stopped, and you may
need further treatment.
