Dotagraf is a contrast medium containing gadoteric acid. It is for diagnostic use only.

Dotagraf is indicated for enhancing the contrast of images obtained by magnetic resonance (MR) imaging. Enhanced contrast improves visualization and delineation in:

Adults and pediatric population (0-18 years)

• Magnetic resonance (MR) imaging of the central nervous system, including defects (lesions) of the brain, spinal cord, and adjacent tissues.

-Magnetic resonance imaging of the whole body, including defects (lesions) of the liver, kidneys, pancreas, pelvis, lungs, heart, breasts, and musculoskeletal system.

Adults

- Magnetic resonance angiography (MRA), including defects (lesions) or narrowing (stenosis) of arteries, except for coronary arteries.

No use Dotagraf

• If you are allergic to the active ingredient or any of the other components of this medication (listed in section 6).
• If you are allergic to medications containing gadolinium (such as other contrast agents used in magnetic resonance imaging procedures).

Advertencias y precauciones

Consult your doctor or radiologist before starting to use Dotagraf if you:

• Have had a reaction to contrast media during a previous test
• Have asthma
• Have a history of allergy (such as shellfish allergy, urticaria, hay fever)
• Are being treated with a beta-blocker (medications used for heart problems and blood pressure alterations, such as metoprolol)

Blood pressure alterations, such as metoprolol)

• Your kidneys do not function correctly
• Recently had, or will soon have, a liver transplant
• Have a disease affecting the heart or blood vessels
• Have had seizures or are being treated for epilepsy

In all these cases, your doctor or radiologist will evaluate the benefit-risk ratio and decide whether you should be administered Dotagraf. If you are administered Dotagraf, your doctor or radiologist will take the necessary precautions and the administration of Dotagraf will be closely monitored.

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

Recién nacidos y lactantes

Due to the immaturity of renal function in newborns up to 4 weeks of age and in infants up to 1 year of age, Dotagraf should be used in these patients only after a careful evaluation by the doctor.

Remove all metal objects you may be wearing before the examination. Inform your doctor or radiologist if you have:

• a pacemaker

• a vascular clip

• an infusion pump

• a neurostimulator

• a cochlear implant (implant in the inner ear)

• any suspected metal foreign body, particularly in the eye.

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

Uso de Dotagraf con otros medicamentos

Inform your doctor or radiologist if you are taking, have recently taken, or may need to take other medications.

Particularly, 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, or angiotensin II receptor antagonists.

Uso de Dotagraf con los alimentos y bebidas

No known interactions exist between Dotagraf and food or drink. However, please consult your doctor, radiologist, or pharmacist if you need to avoid eating or drinking before the test.

Embarazo y lactancia

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

Embarazo

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

Lactancia

Your doctor or radiologist will evaluate whether you should continue or interrupt breastfeeding 24 hours after administering Dotagraf.

Conducción y uso de máquinas

No information is available on the effects of Dotagraf on the ability to drive and use machines.If you feel unwell after the test, you should not drive or use machines.

Dotagraf will be administered by intravenous injection.

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

Dotagraf can be administered manually or using an automatic injector. In newborns and infants, the product will only be administered manually.

The procedure will be performed in a hospital, clinic, or private clinic. Medical personnel are aware of the precautions that must be taken for the test. They are also aware of any possible complications that may occur.

Dosage

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

Special populations dosage

The use of Dotagraf 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 Dotagraf should be received during the procedure and no second injection should be received 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, Dotagraf should only be used after careful evaluation by a doctor. Newborns and infants should only receive one dose of Dotagraf during the procedure and should not receive a second injection 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 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 you use more Dotagraf than you should

It is highly unlikely that you will be given an overdose. Dotagraf will be administered in medical facilities and by a trained person. In a true case of overdose, Dotagraf can be removed from the body by hemodialysis (blood cleaning).

You will find additional information on use and handling by the doctor or healthcare professional at the end of this prospectus.

This information is intended solely for healthcare professionals

Dosage

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.

• Magnetic Resonance (MR) of the brain and spine: The dose may vary from 0.1 to 0.3 mmol per kilogram of body weight (mmol/kg b.w.), equivalent to 0.2 to 0.6 ml/kg b.w. After administration of 0.1 mmol/kg b.w. to patients with brain tumors, an additional dose of 0.2 mmol/kg b.w. may improve tumor characterization and facilitate therapeutic decision-making.
• MR of the whole body and angiography: The recommended dose for intravenous injection is 0.1 mmol/kg of body weight (equivalent to 0.2 ml/kg of body weight) to provide adequate contrast for diagnosis.

Angiography: In exceptional circumstances (e.g. when satisfactory images cannot be obtained with the first dose of a large vascular territory), a second consecutive injection of 0.1 mmol/kg b.w., equivalent to 0.2 ml/kg b.w., may be justified. However, if two consecutive doses of Dotagraf are to be administered before starting angiography, it is recommended to administer only 0.05 mmol/kg b.w., equivalent to 0.1 ml/kg b.w., for each dose, depending on the MR equipment used to obtain the images.

• Pediatric population:

Magnetic Resonance (MR) of the brain and spine / MR of the whole body: The recommended and maximum dose of Dotagraf is 0.1 mmol/kg of body weight. No more than one dose should be used during the procedure.

Due to the immaturity of renal function in newborns up to 4 weeks of age and in infants up to 1 year of age, Dotagraf should be used only in these patients after careful consideration, with a dose not exceeding 0.1 mmol/kg of body weight. No more than one dose should be used during the procedure. Due to the lack of information on repeated administration, Dotagraf injections should not be repeated unless an interval of at least 7 days has elapsed between injections. Dotagraf is not recommended for angiography in children under 18 years of age due to insufficient safety and efficacy data in this indication.

• Patients with renal insufficiency:The dose for adults applies to patients with mild to moderate renal insufficiency (GFR ≥30 ml/min/1.73 m2). See also below the section “Renal insufficiency”.
• Patients with hepatic insufficiency:The dose for adults applies to these patients. Caution should be exercised, especially in the perioperative period of a liver transplant.

Administration

Dotagraf is administered only by intravenous route. Do not use by intrathecal route. Take care to maintain the injection strictly intravenously: extravasation may lead to local intolerance reactions, requiring usual local care.

Infusion rate: 3-5 ml/min (infusion rates up to 120 ml/min, equivalent to 2 ml/sec, may be used in angiographic procedures).

Optimal image acquisition: Approximately 45 minutes after injection.

Optimal image acquisition sequence: Enhanced in T1.

Whenever possible, the intravenous administration of the contrast medium should be performed with the patient in a supine position. After injection, the patient should be kept under observation for at least 30 minutes, as experience shows that most adverse effects occur during this time interval.

Prepare a syringe with a needle. Remove the plastic plug. After cleaning the stopper with a swab or cotton soaked in alcohol, pierce the stopper with the needle. Remove the amount of product needed for the examination and inject it intravenously.

This medicinal product is intended for single use only; unused solution should be discarded.

The injectable solution should be visually inspected before use. Only transparent and particle-free solutions should be used.

Pediatric population

Depending on the amount of Dotagraf to be administered to the child, it is recommended to use Dotagraf vials with a single-use syringe with an adapted volume to achieve better precision of the injected volume.

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

Renal insufficiency

Before administration of Dotagraf, 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 agents in patients with severe acute or chronic renal insufficiency (GFR <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 Dotagraf, it should only be used in patients with severe renal insufficiency and in patients in the perioperative period of a liver transplant after careful consideration of the benefit-risk ratio and if the diagnostic information is essential and cannot be obtained without contrast-enhanced MR. If Dotagraf use is necessary, the dose should not exceed 0.1 mmol/kg of body weight. During the examination, no more than one dose should be administered. Due to the lack of information on repeated administration, Dotagraf administration should not be repeated unless an interval of at least 7 days has elapsed between injections. Hemodialysis shortly after Dotagraf administration may be useful for the elimination of Dotagraf 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.

Older patients

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

Newborns and infants

See the section Posology and administration, pediatric population.

Pregnancy and lactation

Dotagraf 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 Dotagraf administration will be at the discretion of the doctor and the breastfeeding mother.

Handling instructions

The removable label of the vials should be stuck to the patient's medical history to allow for precise recording of the gadolinium-based contrast agent used. The dose used should also be recorded. If the patient's electronic medical history is used, the name of the medicinal product, batch number, and dose should be included in the same.
