Dotarem is a contrast agent used in adults and children. It belongs to the group of contrast agents used for magnetic resonance imaging (MRI). Dotarem is used in magnetic resonance imaging (MRI) examinations to enhance image contrast. The enhancement improves the examination of some body areas.

You should not be administered Dotarem:

Warnings and precautions

Inform your doctor or radiologist in the following cases:

• If you have had a reaction to contrast media during a previous examination.
• If you have asthma
• If you have a history of allergy (such as shellfish allergy, urticaria, hay fever)
• If you are being treated with a beta-blocker (medications used for heart problems, high blood pressure, such as metoprolol)
• If your kidneys do not function correctly
• If you have recently undergone, or are about to undergo, a liver transplant
• If you have a disease affecting the heart or blood vessels
• If you have had seizures or are being treated for epilepsy.

Your doctor or radiologist will evaluate the benefit-risk balance and decide whether you should be administered Dotarem.

If you are administered Dotarem, your doctor or radiologist will take necessary precautions and the administration of Dotarem will be carefully supervised.

Your doctor or radiologist may decide to perform a blood test to check the proper functioning of your kidneys before deciding to use Dotarem, especially if you are 65 years old or older.

Newborns and infants

Due to the immaturity of renal function in newborns up to 4 weeks of age and in infants up to 1 year of age, gadoteric acid should be used only after medical evaluation.

Remove all metal objects you are wearing before the examination. Inform your doctor if you have:

• a pacemaker
• a vascular clip
• a infusion pump
• a nerve stimulator
• a cochlear implant (implant in the inner ear)
• any suspected metal foreign body, particularly in the eye.

This is important because MRI equipment uses very strong magnetic fields, which can cause serious problems.

Use of Dotarem withother medications

Inform your doctor or radiologist if you are taking, have recently taken, or may need to take any other medication. In particular, please inform your doctor, radiologist, or pharmacist if you are taking or have recently taken medications for the heart or blood pressure alterations such as beta-blockers, vasodilators, angiotensin-converting enzyme inhibitors, and angiotensin II receptor antagonists.

Use of Dotarem with food and drinks

There are no interactions between Dotarem and food or drink. However, please consult your doctor, radiologist, or pharmacist if you need to avoid eating or drinking before the test.

Pregnancy and breastfeeding

If you are pregnant or breastfeeding, think you may be pregnant, or plan to become pregnant, consult your doctor or radiologist before using this medication.

Pregnancy:

Gadoteric acid can cross the placenta. Its effects on the fetus are unknown. Dotarem should not be used during pregnancy unless strictly necessary.

Breastfeeding:

Your doctor or radiologist will evaluate whether you should continue breastfeeding or interrupt it for 24 hours after Dotarem administration.

Driving and using machines

No data are available on the effects of Dotarem on driving or using machines. If you feel unwell after the test, experience nausea, you should not drive or use machines.

Dotarem is administered intravenously.

During the examination,You will be under the supervision of a doctor or radiologist. A plastic needle will be left in your vein; this will allow the doctor to inject emergency medications, if necessary. If you experience an allergic reaction, Dotarem administration will be stopped.

Dotarem can be administered manually or using an automatic injector.In newborns and infants, the medication must be administered manually.

The procedure will be performed in a hospital or clinic. Healthcare personnel know the precautions that must be taken for the examination. They also know any possible complications that may arise.

Dose

Your doctor or radiologist will determine the dose you will receive and supervise the injection.

Posology in special populations

The use of Dotarem is not recommended in patients with severe kidney problems or in patients who have recently had or will soon have a liver transplant. However, if use is required, only one dose of Dotarem should be administered during an examination, and a second injection should not be administered until at least 7 days have passed.

Newborns, infants, children, and adolescents

Due to the immaturity of renal function in newborns up to 4 weeks of age and in infants up to 1 year of age, gadoteric acid should only be used after medical evaluation.

Children should only receive one dose of Dotarem during the scan and should not receive a second dose until at least 7 days have passed.

The use for angiography is not recommended in children under 18 years old.

Older adults

If you are 65 years old or older, it is not necessary to adjust the dose, but you may be required to have a blood test to check the proper functioning of your kidneys.

If too much Dotarem has been administered

It is highly unlikely that you will be given an overdose. Dotarem will be administered after medical adjustment by a trained person. In the event of an overdose, Dotarem can be removed from the body by hemodialysis (blood cleaning).

In case of overdose or accidental ingestion, contact the Toxicological Information Service. Phone 91 562 04 20.

_____________________________________________________________________________

This information is intended solely for the doctor or healthcare professional:

Dosage and administration:

Use the lowest dose that provides sufficient enhancement for diagnostic purposes. The dose should be calculated based on the patient's body weight and should not exceed the recommended dose per kilogram of body weight indicated in this section.

The recommended dose is 0.1 mmol/kg of body weight (i.e. 0.2 ml/kg of body weight) for all authorized indications.

Only if necessary, a higher dose may be administered exclusively in the following indications:

- For the detection and/or characterization of primary and secondary brain tumors (known or suspected) a dose of 0.3 mmol/kg of body weight (i.e. 0.6 ml/kg of body weight) may be administered, in the form of two consecutive intravenous injections in bolus: a first injection of 0.1 mmol/kg of body weight, followed 20 minutes later by another injection of 0.2 mmol/kg of body weight.

-In magnetic resonance angiography for arterial study (except for coronary arteries) a second consecutive injection of 0.1 mmol/kg of body weight may be justified, administered under the same conditions as the first, only in exceptional circumstances (for example, if it is impossible to obtain satisfactory images with the first dose because the moment of image acquisition has not been perfect, the vascular territory is too extensive or there is lateralization of hemodynamic alterations in bilateral vascular territories). However, if it is presumed that two consecutive doses of DOTAREM will be administered before starting the arteriography of certain regions (such as the lungs or lower extremities), it is advisable to administer only 0.05 mmol/kg of body weight for each dose, depending on the MRI equipment to be used to obtain the images.

Pediatric population (0-18 years)

The maximum recommended dose is 0.1 mmol/kg of body weight (i.e. 0.2 ml/kg of body weight) for all authorized indications, except formagnetic resonance angiography for arterial study. No more than one dose should be administered during the scan.

• Due to the immaturity of renal function in newborns up to 4 weeks of age and in infants up to 1 year of age, Dotarem should only be used in these patients after careful consideration, with a dose that does not exceed 0.1 mmol/kg of body weight. No more than one dose should be administered during the scan. Due to the lack of information on consecutive administration, Dotarem injections should not be repeated unless there is an interval of at least 7 days between injections.
• Acid Gadoterico is not recommended formagnetic resonance angiography for arterial studyin children under 18 years of age, because the safety and efficacy data in this indication are insufficient.

Geriatric population (population over 65 years of age)

No dose adjustment is considered necessary. Caution should be exercised in elderly patients.

Before administering Dotarem, it is recommended to evaluate all patients to detect possible renal dysfunction by laboratory tests.

Cases of systemic fibrosis nephrogenica (FNS) have been reported associated with the use of some gadolinium-based contrast media in patients with severe acute or chronic renal insufficiency (TFG or glomerular filtration rate <30>2). Patients undergoing liver transplantation have a special risk since the incidence of acute renal failure is high in this group. Since there is a possibility that FNS may occur with Dotarem, it should only be used in patients with severe renal insufficiency and in patients in the perioperative period of liver transplantation after careful evaluation of the risk/benefit ratio and si the diagnostic information is essential and cannot be obtained without contrast MRI. If Dotarem use is necessary, the dose should not exceed0.1 mmol/kg of body weight. During the examination, no more than one dose should be administered. Due to the absence of information on repeated administration, Dotarem administration should not be repeated unless there is an interval of at least 7 days between injections.

Since renal elimination of gadoteric acid may be reduced in elderly patients, it is especially important to evaluate patients 65 years or older to detect possible renal dysfunction.

Hemodialysis shortly after Dotarem administration may be useful for the elimination of Dotarem from the body. There is no evidence to support the initiation of hemodialysis for the prevention or treatment of FNS in patients not undergoing hemodialysis.

Dotarem should not be used during pregnancy unless the woman's clinical situation requires treatment with gadoteric acid.

The continuation or interruption of breastfeeding 24 hours after administration of gadoteric acid will be at the discretion of the doctor and the mother in the breastfeeding period.

Administration forms:

When using Dotarem, the usual safety precautions in MRI should be observed.

Dotarem should not be administered by intrathecal (subarachnoid) or epidural injection. Administration route: strictly intravenous.

While the examination is being performed, medical supervision and maintenance of a venous access route for any symptomatic therapy that may be required, as well as other specific precautions (see“Before using Dotarem”)

The patient should remain fasting for 2 hours before the examination to avoid aspiration, and the equipment and medications necessary for treating anaphylactic reactions should be available. Additionally, the intravascular administration of the contrast medium should be performed, if possible, with the patient lying down. After administration, the patient should remain under observation for at least half an hour, since most adverse effects occur during this time.

Depending on the amount of gadoteric acid administered to the child, it is preferable to use vials of gadoteric acid with a single-use syringe with an adapted volume to ensure greater accuracy of the injected volume.

In newborns and infants, the required dose should be administered manually.

Instructions for use:

Dotarem is an injectable solution that is presented in vials with a rubber stopper of 5, 10, 15, 20 ml and in bottles of 60 and 100 ml for use with an injector.

Use of vials of 5, 10, 15 and 20 ml:

The preparation of the contrast medium requires lifting the plastic disc from the bottle, cleaning the stopper with alcohol and piercing it with a needle incorporated in a syringe, and extracting the amount of product necessary for the test.

Use of bottles of 60 ml and 100 ml for use with an injector:

The contrast medium should be administered through an automatic injector, the use of which is prohibited in children under 2 years of age.

The rubber stopper should only be pierced with a suitable extraction device (spike). In general, the extraction device should have the following characteristics: trocar, sterile air filter, luer closure with protective cap and antireflux system.

The patient tube should be changed after each examination. The contrast medium remaining in the bottle, the connecting tubes and all the disposable parts of the injection system should be discarded at the end of each examination session. Any specific instructions from the equipment manufacturer should also be followed.

All injection solutions should be visually inspected before use. Only transparent and particle-free solutions should be used.

The separable label of the vials/bottles should be stuck to the patient's history to allow for a precise record of the gadolinium-based contrast medium used. The dose used should also be recorded. If the patient's electronic history is used, the name of the medicine, batch number and dose should be included in the same.
