1. What Gadobutrol is and what it is used for

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).

How Gadobutrol works

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.

2. What you need to know before you are given Gadobutrol
Do NOT use Gadobutrol if you
  • are allergic to gadobutrol or any of the other ingredients of this medicine (listed in section 6).

Warnings and precautions

Talk to your doctor before you are given Gadobutrol if you

  • suffer or have suffered from an allergy (e.g. hay fever, hives) or asthma
  • had a previous reaction to any contrast media
  • have very poor kidney function
  • suffer from brain conditions with seizures (fits) or from other diseases of the nervous system
  • have a heart pacemaker or if there are any implants or clips containing iron in your body.

Your doctor will decide whether the intended examination is possible or not.

  • Allergy-like or other types of reactions leading to heart problems, breathing difficulties or skin reactions may occur after use of Gadobutrol. Severe reactions are possible. Most of these reactions occur within half an hour after you are given Gadobutrol. Therefore, you will be observed after the examination. Delayed reactions have been observed (after hours or days) (see section 4).

Kidneys/Liver

Tell your doctor if

  • your kidneys do not work properly
  • you have recently had, or soon expect to have, a liver transplant.

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.

Neonates and infants

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.

Other medicines and Gadobutrol

Tell your doctor if you are taking or have recently taken or might take any other medicines.

Pregnancy and breast-feeding

Ask your doctor for advice before taking any medicine.

  • Pregnancy

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.

  • Breast-feeding

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.

Gadobutrol contains sodium

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’.

3. How Gadobutrol will be given

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 usual dose

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.

Dosage in special patient groups

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.

Neonates, infants, children and adolescents

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.

Elderly

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.

If you receive more Gadobutrol than you should

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.

4. Possible side effects

Like all medicines, this medicine can cause side effects, although not everybody gets them. Most of these reactions occur within half an hour after you are given Gadobutrol. Delayed allergy-like or other types of adverse reactions, occuring hours to several days after you have received Gadobutrol, have been observed in rare cases. If this should happen to you, tell your doctor or radiologist immediately.

The most serious side effects (which have been fatal or life-threatening in some cases) are:

  • heart stops beating (cardiac arrest), a severe lung disease (acute respiratory distress syndrome) / fluid in the lungs (pulmonary oedema) and severe allergy-like (anaphylactoid) reactions (including stop of breathing and shock).

In addition for the following side effects life-threatening or fatal outcomes have been observed in some cases:

  • shortness of breath (dyspnoea), loss of consciousness, severe allergy-like reaction, severe decrease of blood pressure may lead to collapse, stop of breathing, fluid in the lungs, swelling of mouth and throat and low blood pressure.

In rare cases:

  • allergy-like reactions (hypersensitivity and anaphylaxis) may occur, including severe reactions (shock) that may need immediate medical intervention.

If you notice:

  • swelling of the face, lips, tongue or throat
  • coughing and sneezing
  • difficulty breathing
  • itching
  • runny nose
  • hives (nettle-type rash)

tell the MRI department staff immediately. These may be the first signs that a severe reaction is happening. Your investigation may need to be stopped and you may need further treatment.

The most frequently observed side effects (may affect 5 or more in 1,000 people) are:

  • headache, feeling sick (nausea) and dizziness.

Most of the side effects are mild to moderate.
