Gadobutrol is a contrast medium for magnetic resonance imaging (MRI) used for diagnostics of the brain, spine and vessels. Gadobutrol can also help the doctor find out the kind (benign or malignant) of known or suspected abnormalities in the liver and kidneys.
Gadobutrol can also be used for MRI of abnormalities of other body regions.
It facilitates visualisation of abnormal structures or lesions and helps in the differentiation between healthy and diseased tissue.
It is for use in adults and children of all ages (including term newborn infants).
MRI is a form of medical diagnostic imaging that uses the behaviour of water molecules in normal and abnormal tissues. This is done by a complex system of magnets and radio waves. Computers record the activity and translate that into images.
Gadobutrol is given as an injection into your vein. This medicine is for diagnostic use only and will only be administered by healthcare professionals experienced in the field of clinical MRI practice.
Talk to your doctor before you are given Gadobutrol if you
Your doctor will decide whether the intended examination is possible or not.
Tell your doctor if
Your doctor may decide to take a blood test to check how well your kidneys are working before making the decision to use Gadobutrol, especially if you are 65 years of age or older.
As kidney function is immature in babies up to 4 weeks of age and infants up to 1 year of age, Gadobutrol will only be used in these patients after careful consideration by the doctor.
Tell your doctor if you are taking or have recently taken or might take any other medicines.
Ask your doctor for advice before taking any medicine.
Gadobutrol can cross the placenta. It is not known whether it affects the baby. You must tell your doctor if you think you are, or might become, pregnant as Gadobutrol should not be used during pregnancy unless strictly necessary.
Tell your doctor if you are breast-feeding or about to start breast-feeding. Your doctor will discuss whether you should continue or interrupt breast-feeding for a period of 24 hours after you receive Gadobutrol.
This medicinal product contains less than 23 mg sodium per dose (based on the average amount given to a 70 kg person), i.e. essentially ‘sodium-free’.
Gadobutrol is injected into your vein using a small needle by a healthcare professional. Your MRI examination can start immediately.
After the injection you will be observed for at least 30 minutes.
The actual dose that is right for you will depend on your body weight and on the region being examined by MRI:
In adults a single injection of 0.1 millilitre Gadobutrol per kg body weight is recommended (this means for a person weighing 70 kg the dose would be 7 millilitre), however a further injection of up to 0.2 millilitre per kg body weight within 30 minutes of the first injection may be given. A total amount of 0.3 millilitre Gadobutrol per kg body weight may be given at maximum (this means for a person weighing 70 kg the dose would be 21 millilitres) for imaging of the central nervous system (CNS) and CE-MRA. A dose of 0.075 millilitres Gadobutrol per kg body weight may be given at minimum (this means for a person weighing 70 kg the dose would be 5.25 millilitres) for the CNS.
Further information regarding the administration and handling of Gadobutrol is given at the end of the leaflet.
The use of Gadobutrol is not recommended in patients with severe kidney problems and patients who have recently had, or soon expect to have, a liver transplant. However if use is required you should only receive one dose of Gadobutrol during a scan and you should not receive a second injection for at least 7 days.
In children of all ages (including term newborn infants) a single dose of 0.1 millilitre Gadobutrol per kg body weight is recommended for all examinations (see section 1).
As kidney function is immature in babies up to 4 weeks of age and infants up to 1 year of age, Gadobutrol will only be used in these patients after careful consideration by the doctor. Neonates and infants should only receive one dose of Gadobutrol 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 may have a blood test to check how well your kidneys are working.
Overdosing is unlikely. If it does happen, the doctor will treat any symptoms and may use kidney dialysis to remove Gadobutrol from your body.
There is no evidence to suggest that this will prevent the development of Nephrogenic Systemic Fibrosis (NSF; see section 4) and it should not be used as treatment for the condition. In some cases your heart will be checked.
If you have any further questions on the use of this medicine, ask your doctor or radiologist.
