1. What Clariscan is and what it is used for

What is Clariscan?

Clariscan contains the active substance gadoteric acid. It belongs to a group of medicines called “contrast agents” for magnetic resonance imaging (MRI).

What Clariscan is used for

Clariscan is used to increase the contrast of the images obtained during MRI scans.

In adults and children and adolescents (0-18 years):

– MRI of the central nervous system including defects (injuries) in the brain, spine / spinal cord, and surrounding tissue.

In adults and children and adolescents (6 months-18 years):

– Full-body MRI including defects (injuries)

In adult patients only:

– magnetic resonance angiography (MRA) including defects (injuries) or narrowing of arteries (stenosis), except in coronary arteries.

This medicine is used only to make a diagnosis.

How Clariscan works

Clariscan makes the images from an MRI scan easier to interpret, by increasing the contrast between the body part being examined and the rest of the body. This allows the doctor to see different parts of the body better.

Gadoteric acid contained in Clariscan may also be approved for the treatment of other conditions not mentioned in this product information. Ask your doctor, pharmacist, or other healthcare professional if you have any further questions and always follow their instructions.

2. What you need to know before you are given Clariscan

Do not use Clariscan

  • if you are allergic to gadoteric acid or any of the other ingredients of this medicine (listed in section 6).
  • if you are allergic to medicines containing gadolinium or any other contrast medicine used for MRI.

Warnings and cautions

Remove any metal objects you are wearing before the examination.

Talk to your doctor or radiologist before receiving Clariscan if:

  • you have previously had a hypersensitivity reaction to a contrast agent
  • you have asthma
  • you have allergies are – e.g. shellfish allergy, pollen allergy, hives (intense itching)
  • you are being treated with a beta-blocker (medicines for heart and blood pressure diseases such as metoprolol )
  • your kidneys are not functioning normally
  • you have recently undergone, or probably will soon undergo, a liver transplant
  • you have had seizures (seizures or seizures) or you are being treated for epilepsy.
  • you have serious heart problems
  • you have any disease that affects your heart or your blood vessels
  • you have a “pace-maker”, vascular clamps that contain iron (ferromagnetic), an implant or an insulin pump, or foreign objects of metal in/on the body, especially in the eye. In these cases, MRI scans are not appropriate.

If any of the above applies to you, talk to your doctor before receiving Clariscan.

Risk of serious side effect s

As with all MRI contrast agents, there is a risk of side effect. The side effects are usually less severe and transient but cannot be predicted. However, there is a risk that they may endanger your life:

• any serious side effects may occur immediately or within one hour of receiving the medicine

• minor side effects may occur up to 7 days after treatment. Side effects are more likely if you have previously had a hypersensitivity reaction to an MRI contrast agent (see section 4 “Possible side effects”)

• tell your doctor before giving Clariscan if you have had a reaction in the past. Your doctor will only give you Clariscan if the benefits outweigh the risks. If you receive Clariscan, you will be closely monitored by your doctor.

Samples and examinations

Your doctor may decide to take a blood sample before you receive Clariscan, especially if you are over 65 years old. This is to check how well your kidneys are working.

Children and young people

Use for angiography is not recommended for children under 18 years of age.

Newborns and infants

Your doctor will carefully consider whether your child can be given Clariscan. This is because the kidneys are immature in newborns up to 4 weeks of age and infants up to 1 year of age.

Use in whole-body MRI is not recommended for children under 6 months.

Other medicines and Clariscan

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

In particular, tell your doctor if you are taking or have recently taken medicines for heart disease and high blood pressure such as:

  • Beta-blockers, medicines that slow down your heart (eg metoprolol )
  • substances that enlarge (dilate) your blood vessels and lower blood pressure: vasoactive substances (such as doxazosin ), ACE inhibitors (such as ramipril), angiotensin II receptor antagonists (such as valsartan).

Tell your doctor if you are taking or have recently taken any of the medicines listed above.

Clariscan with food and drink

Nausea and vomiting are known possible side effects when using contrast agents in MRI. The patient should therefore refrain from eating later than 2 hours before the examination.

Pregnancy and breastfeeding


If you are pregnant, think you may be pregnant, or are planning to have a baby, ask your doctor for advice before taking this medicine. Clariscan should not be used during pregnancy unless clearly necessary by your doctor.


If you are breast-feeding or planning to breast-feed, talk to your doctor before using this medicine. Discuss with your doctor if you should continue breast-feeding or if you should stop breastfeeding for a period of 24 hours after receiving Clariscan.

Driving and using machines

There is no information on the effects of Clariscan on the ability to drive. Take into account any side effects such as dizziness (symptoms of low blood pressure ) and nausea when driving or using machines. If you feel unwell after the examination, do not drive or use machines.

You are responsible for assessing whether you are fit to drive a motor vehicle or perform work that requires increased attention. One of the factors that can affect your ability in these respects is the use of drugs due to their effects and/or side effects.

Descriptions of these effects and side effects can be found in other sections. Read all the information in this leaflet for guidance. If you are not sure, talk to your doctor or pharmacist.

3. How Clariscan is given

How to use Clariscan

Clariscan is given to you via intravenous injection.

The procedure is performed in a hospital, clinic, or private practice.

The staff knows what precautions must be taken during the examination.

They also know what possible complications can occur.

During the examination, you will be monitored by a doctor.

  • A needle is left in your vein.
  • In this way, the doctor can inject suitable emergency medicines if needed.

If you get an allergic reaction, the administration of Clariscan is stopped.

How much medicine will you get?

The doctor decides what dose to take and monitors the injection.

Patients with liver or kidney problems

Clariscan is not recommended for use in patients with severe kidney problems and patients who have recently had, or are expected to undergo, a liver transplant.

If your doctor still thinks you should get Clariscan:

  • You should only receive one dose of Clariscan during an MRI scan
  • and you should not receive any more injection in at least 7 days.

Use for newborns, infants, children, and adolescents

Clariscan should only be given to these patients after careful consideration by your doctor.

If your doctor thinks your child should get Clariscan:

• the child should only receive one dose of Clariscan, during an MRI scan

• and the child should not receive another injection for at least 7 days.

Use of full-body MRI is not recommended for children under 6 months.

Use for angiography is not recommended for children under 18 years of age.


It is not necessary to adjust the dose if you are 65 years or older, but you will have to take a blood sample to examine how well your kidneys are working.

If you take more Clariscan than you should

It is very unlikely that you would get an overdose because you are being given Clariscan in a medical setting by a trained person.

If you really get an overdose, Clariscan can be removed from your body by hemodialysis (blood purification).

There is more information on use and handling for healthcare professionals at the end of this leaflet.

If you have any further questions on the use of this product, ask your doctor.

4. Possible side effects

Has been reported (occurs in an unknown number of users)

Nitrogen systemic fibrosis

This is a disease that causes the skin to thicken and harden and can also affect soft parts and internal organs. This has most commonly occurred in patients receiving Clariscan with other contrast agents containing gadolinium.
