1. What DOTAREM is and what it is used for

DOTAREM is a diagnostic agent used in adults and children. It belongs to a group of
contrast agents used in magnetic resonance imaging (MRI).
DOTAREM is used to enhance the contrast of images obtained during MRI scans.
This contrast enhancement improves the visibility and definition of the borders of:

  • abnormalities in the brain, spinal cord, and surrounding tissues;
  • abnormalities in the liver, kidneys, pancreas, pelvis, lungs, heart, breast, and musculoskeletal system;
  • abnormalities and narrowing in blood vessels, especially in the coronary arteries (in adults only).

This medicine is intended for diagnostic use only.

2. Important information before using DOTAREM

When NOT to use DOTAREM

  • if the patient is allergic to the active substance or to any of the other ingredients of this medicine (listed in section 6).
  • if the patient is allergic to drugs containing gadolinium (such as other contrast agents used in magnetic resonance imaging).

Warnings and precautions
You must inform your doctor or radiologist if any of the following apply to the patient:

  • the patient has previously experienced a reaction to a contrast agent during an examination;
  • the patient has asthma;
  • the patient has a history of allergies (e.g. allergy to seafood, hives, hay fever);
  • the patient is being treated with beta-blockers (medicines used to treat heart conditions and high blood pressure, such as metoprolol);
  • the patient's kidneys are not functioning properly;
  • the patient has recently undergone or is scheduled for a liver transplant;
  • the patient has a disease affecting the heart or blood vessels;
  • the patient has had seizures or is being treated for epilepsy.

In all such cases, the doctor or radiologist will evaluate the benefit-risk ratio and determine whether DOTAREM can be administered to the patient. If DOTAREM is administered, the doctor or radiologist will take necessary precautions and the administration of DOTAREM will be closely monitored.
The doctor or radiologist may decide to perform blood tests to check the patient's kidney function before administering DOTAREM, especially in patients aged 65 years and older.

Newborns and infants
Due to the immaturity of kidney function in newborns up to 4 weeks of age and infants up to 1 year of age, DOTAREM will be used in such patients only after careful consideration by the doctor.

Before the examination, all metallic objects the patient may be wearing should be removed. You must inform the doctor or radiologist if the patient has any of the following implanted:

  • cardiac pacemaker,
  • vascular clip,
  • infusion pump,
  • nerve stimulator,
  • cochlear implant (inner ear implant),
  • any suspected metallic foreign body, especially in the eye. This is very important, as serious problems may occur due to the use of very strong magnetic fields in magnetic resonance imaging equipment.

DOTAREM and other medicines
You must tell the doctor or radiologist about all medicines the patient is currently taking or has recently taken, as well as any medicines the patient plans to take. In particular, inform the treating physician, radiologist, or pharmacist if the patient is taking or has recently taken medicines for heart conditions and high blood pressure, such as beta-blockers, vasoactive agents, angiotensin-converting enzyme (ACE) inhibitors, or angiotensin II receptor antagonists.

DOTAREM with food and drink
No interactions between DOTAREM and food or drink are known. However, you should ask your doctor, radiologist, or pharmacist whether it is necessary to avoid eating or drinking before the examination.

Pregnancy and breastfeeding
If the patient is pregnant or breastfeeding, suspects she may be pregnant, or is planning to have a child, she should consult her doctor or radiologist before using this medicine.

Pregnancy
Gadoteric acid may cross the placenta. It is not known whether this may affect the unborn child.
DOTAREM must not be used during pregnancy unless absolutely necessary.

Breastfeeding
The doctor or radiologist will discuss with the patient and advise whether she may continue breastfeeding or should interrupt it for 24 hours after administration of DOTAREM.

Driving and using machines
There are no available data on the effects of DOTAREM on the ability to drive. If the patient feels unwell after the examination, for example nausea (feeling sick), the patient should not drive or operate machinery.

3. How to use DOTAREM

DOTAREM will be administered as an intravenous injection.
During the examination, the patient will be closely monitored by a physician or radiologist. An intravenous catheter will remain in place in the patient's vein so that, if necessary, the physician or radiologist can rapidly administer life-saving medications. If the patient experiences an allergic reaction, administration of DOTAREM will be immediately discontinued.
DOTAREM may be injected manually or using an automated injector.
In neonates and infants, this medicine is administered exclusively by manual injection.
The procedure may be performed in a hospital, outpatient clinic, or private office. Medical personnel are aware of the precautions to be taken during the examination and are familiar with potential complications that may occur.

Dosage
The physician or radiologist will determine the appropriate dose for the patient and will supervise the injection of the medicine.

Dosage in special patient groups
DOTAREM is not recommended for patients with severe renal function impairment or for patients who have recently undergone or are scheduled to undergo liver transplantation. However, if administration of DOTAREM is considered necessary, the patient should receive only a single dose during the examination and should not receive another dose within at least 7 days.

Use in neonates, infants, children, and adolescents
Due to immature kidney function in neonates up to 4 weeks of age and infants up to 1 year of age, DOTAREM will be used in such patients only after careful physician evaluation. Children should receive only a single dose during the examination and should not receive another injection within at least 7 days.
Use in angiography is not recommended in children under 18 years of age.

Elderly patients
Dosage adjustment is not required for patients aged 65 years and older; however, blood tests to assess kidney function may be necessary.

Administration of a higher than recommended dose of DOTAREM
It is highly unlikely that a patient would receive an overdose of the medicine. DOTAREM is administered in a medical facility by appropriately trained personnel. In the event of an actual overdose, DOTAREM can be removed from the body by hemodialysis (blood cleansing).

Additional information on the use and handling of this medicine by medical personnel is provided at the end of this leaflet.
If you have any further questions about the use of this medicine, consult your physician or radiologist.

4. Possible adverse reactions

Like any medicine, this medicine can cause adverse reactions, although not everyone will experience them.

Information intended exclusively for medical professionals or healthcare personnel:
Dosage

Adults:

  • Brain and spinal MRI: For neurological system imaging, doses range from 0.1 to 0.3 mmol/kg body weight, corresponding to 0.2 to 0.6 ml/kg body weight. After administering 0.1 mmol/kg body weight to patients with brain tumours, administration of an additional dose of 0.2 mmol/kg body weight may improve tumour visibility and facilitate treatment decisions.
  • Whole-body MRI and angiography: The recommended intravenous dose providing adequate diagnostic contrast is 0.1 mmol/kg body weight (i.e. 0.2 ml/kg body weight).
  • Angiography: In exceptional circumstances (e.g. when satisfactory image quality covering a large vascular area has not been achieved), administration of a second, subsequent dose of 0.1 mmol/kg body weight (corresponding to 0.2 ml/kg body weight) may be justified. However, if two consecutive doses of DOTAREM are anticipated before starting angiography, it may be preferable to administer 0.05 mmol/kg body weight (i.e. 0.1 ml/kg body weight) for each dose, depending on the available imaging equipment.

Children and adolescents (0–18 years):

  • Brain and spinal MRI / Whole-body MRI: The recommended and maximum dose of DOTAREM is 0.1 mmol/kg body weight. More than one dose should not be administered during a single imaging session. Due to the immaturity of renal function in newborns up to 4 weeks of age and infants up to 1 year of age, DOTAREM should be used in these patients only after careful consideration and at a dose not exceeding 0.1 mmol/kg body weight. More than one dose should not be administered during a single imaging session. Due to lack of data on repeated administration, repeat injections of DOTAREM should not be given unless the interval between doses is at least 7 days.

  • Angiography: The use of DOTAREM is not recommended for angiography in children under 18 years of age due to insufficient data on efficacy and safety for this indication.

Special patient groups:

  • Patients with impaired renal function: In patients with mild to moderate renal impairment (GFR ≥30 ml/min/1.73 m²), the adult dose should be used. See section "Renal function impairment" below.
  • Patients with impaired liver function: In such patients, the adult dose should be used. Caution is recommended, especially in the perioperative period related to liver transplantation.

Method of administration
DOTAREM is indicated exclusively for intravenous administration. DOTAREM must not be administered intrathecally or epidurally.
Infusion rate: 3–5 ml/min (in angiographic procedures, a higher infusion rate up to 120 ml/min, i.e. 2 ml/sec, may be used).
Optimal imaging window: within 45 minutes after injection.
Optimal imaging sequence: T1-weighted images.
Whenever possible, the contrast agent should be administered intravenously to the patient in a lying position. After administration, the patient should be monitored for at least 30 minutes, as experience shows that most adverse reactions occur during this period.
Prepare a syringe with a needle. Remove the plastic disk. Clean the stopper with an alcohol swab and/or gauze, then pierce the stopper with the needle. Withdraw the volume of product required for the examination and administer it intravenously to the patient.
For single use only; any unused portions must be discarded.
The injection solution should be inspected visually prior to use. Only clear solutions free from visible particles should be used.

Children and adolescents (0–18 years)
Depending on the amount of DOTAREM to be administered to a child, it is recommended to use vials of DOTAREM in combination with a single-use syringe of appropriate capacity to ensure higher precision of the administered dose.
In newborns and infants, the required dose should be administered manually.

Renal function impairment
It is recommended that all patients undergo laboratory tests to assess renal function before administration of DOTAREM.
There have been reports of nephrogenic systemic fibrosis (NSF) associated with the use of gadolinium-containing contrast agents in patients with acute or chronic renal impairment (GFR <30 ml/min/1.73 m²). Patients undergoing liver transplantation are at particular risk due to the high frequency of acute renal failure in this group. Because of the risk of NSF associated with the use of DOTAREM, this product should be used in patients with severe renal impairment and in patients in the perioperative period of liver transplantation only after careful benefit-risk assessment and only when diagnostic information is essential and cannot be obtained by non-contrast MRI. If DOTAREM must be used, the dose should not exceed 0.1 mmol/kg body weight. More than one dose should not be administered during a single imaging session. Due to lack of data on repeated administration, repeat injections of DOTAREM should not be given unless the interval between doses is at least 7 days.
Haemodialysis shortly after administration of DOTAREM may facilitate elimination of DOTAREM from the body. There is no evidence to support initiating haemodialysis for prevention or treatment of NSF in patients who are not currently undergoing haemodialysis.

Elderly patients
Since renal clearance of gadoteric acid may be reduced in elderly patients, it is particularly important to assess renal function in patients aged 65 years and older prior to administration.

Newborns and infants
See section "Dosage and method of administration, use in children".

Effect on pregnancy and breastfeeding
DOTAREM should not be used during pregnancy unless the clinical condition of the woman requires the use of gadoteric acid.
Continuation or interruption of breastfeeding for 24 hours after administration of DOTAREM should be decided by the physician and the breastfeeding mother.

Instructions for use
The peel-off identification labels from the vials should be attached to the patient's records to allow accurate identification of the gadolinium-containing contrast agent used. The administered dose should also be recorded. When using an electronic patient record, the product name, batch number, and administered dose should be entered.
