This medication is solely for diagnostic use.

Iomeron belongs to a group of medications known as low osmolar, water-soluble, and nephrotropic X-ray contrast media.

Iomeron is used to improve visualization of different body areas through certain radiological techniques. It is used in adults for intravenous urography, computed tomography (CT) of the body, conventional angiography, angiocardiography, selective conventional coronary arteriography, digital subtraction phlebography, digital subtraction arteriography, arthrography, hysterosalpingography, fistulography, galactography, dacryocystography, sialography, and retrograde cholangiography..In children aged 0 to 18 years for intravenous urography, computed tomography (CT) of the body, conventional interventional arteriography, angiocardiography, digital subtraction phlebography, and digital subtraction arteriography..

No use Iomeron 350 mg Iodo/ml solución inyectable

Genital ultrasound examinations are contraindicated in case of suspected pregnancy or confirmed pregnancy and in case of acute inflammation.

Warnings and precautions

It is recommended to perform a fluoroscopy to minimize the extravasation during the injection.

You may experience a short-term cerebral disorder, called encephalopathy, during or shortly after the imaging procedure. Inform your doctor immediately if you notice any of the symptoms related to this condition, described in section 4.

Thyroid disorders have been observed after administration of Iomeron in both children and adults. Newborns may also be exposed through the mother during pregnancy. Your doctor may need to perform thyroid function tests before and/or after administration of Iomeron.

Severe skin reactions, including Stevens-Johnson syndrome (SSJ), toxic epidermal necrolysis (NET), acute generalized pustular psoriasis (PEGA), and drug reaction with eosinophilia and systemic symptoms (DRESS), have been reported associated with the use of Iomeron. Seek medical attention immediately if you observe any of the symptoms related to these severe skin reactions described in section 4.

Consult your doctor before starting to use Iomeron 350 mg Iodo/ml injectable solution.

Children

Children under one year of age, especially newborns, are particularly susceptible to electrolyte imbalances and hemodynamic alterations.

Other medications and Iomeron 350 mg Iodo/ml injectable solution

Inform your doctor if you are using, have used recently, or may need to use any other medication.

Do not interrupt treatment with anticonvulsant medications and ensure their administration in optimal doses.

In patients treated with immunomodulatory medications, such as Interleukin-2, allergic reactions to contrast media are more frequent and may manifest as delayed reactions.

This medication should not be mixed with others.

Interference with laboratory tests:

Iodinated contrast media may interfere with thyroid function tests, as the thyroid's ability to capture radioisotopes will be reduced for periods of two weeks or more.

High concentrations of contrast media in plasma and urine may alter the results of laboratory tests for bilirubin, proteins, and inorganic substances (e.g. iron, copper, calcium, phosphate).

Use of Iomeron350 mg Iodo/ml injectable solution with food and beverages

If there are no specific instructions from your doctor, you can follow a normal diet on the day of the examination. Confirm adequate fluid intake. However, you should refrain from eating for two hours before the examination.

Pregnancy and lactation

If you are pregnant or breastfeeding, or if you think you may be pregnant, consult your doctor before using this medication.

Pregnancy

Inform your doctor if you are pregnant or think you may be.

Like other non-ionic contrast media, there are no controlled studies in pregnant women that confirm the safety of the product in humans. Since, whenever possible, exposure to radiation during pregnancy should be avoided, the risk-benefit ratio of any X-ray examination, with or without contrast medium, should be carefully evaluated.

If you are pregnant and have received Iomeron during pregnancy, it is recommended to analyze the thyroid function of your newborn.

Lactation

Contrast media are rarely excreted in breast milk, and it is remote that the infant may be harmed.

Driving and operating machinery

No effects on the ability to drive and operate machinery are known.

This medication will always be administered by qualified and properly trained personnel, in hospitals or clinics that have the necessary personnel and equipment.

The dose you will receive will vary depending on the type of examination, age, body weight, cardiac output, and general condition you present, as well as the technique used.

If you use more Iomeron 350 mg Iodo/ml injectable solution than you should

Overdosing may cause severe adverse reactions, mainly through effects on the cardiovascular and pulmonary systems.

The treatment of an overdose is aimed at maintaining all vital functions and preventing the rapid onset of symptomatic therapy. Iomeron can be eliminated from the body through dialysis.

In case of overdose or accidental ingestion, consult your doctor or pharmacist or call the Toxicological Information Service, phone 91 562 04 20, indicating the medication and the amount ingested.

If you have doubts about the use of this product, consult with your doctor or pharmacist.

Like all medicines, this medicine can cause side effects, although not everyone will experience them.

<-------------------------------------------------------------------------------------------------------------->

This information is intended only for healthcare professionals:

Iomeron 350 mg Iodo/ml is an injectable solution for intravenous, intraarterial, intracolangiopancreatic, intraarticular, intrauterine, intramammary, and intraglandular administration.

Whenever possible, intravascular administration of contrast media should be performed with the patient lying down. The patient should be kept under observation for at least 30 minutes after administration.

Before use, the solution must be visually inspected. Only solutions without visible signs of deterioration or particles will be used.

Instructions for administration if single-dose vials are used:

Do not extract multiple doses from a vial of contrast medium. The rubber stopper should never be perforated more than once. It is recommended to use an appropriate extraction cannula to pierce the stopper and extract the contrast medium. This should not be extracted into the syringe until immediately before use. The residual amount of solution not used for an examination should be discarded.

Instructions for administration if multi-dose vials are used:

Multi-dose vials should only be used connected to autoinjectors/pumps.

Autoinjectors/pumps should not be used in small children.

A single perforation should be made.

The connection line leading from the autoinjector/pump to the patient should be changed after each patient.

The surplus contrast medium remaining in the vial, as well as the connection tubes and all replaceable parts of the injection system, should be discarded within 8 hours.

It is essential to follow the additional instructions provided by the manufacturer of the autoinjector/pump strictly.

The elimination of unused medication and all materials that have come into contact with it will be carried out in accordance with local regulations.

Precautions

• Regarding the patient:

Hydration- Any severe electrolyte imbalance should be corrected. Adequate hydration should be ensured before the examination, especially in patients with severe renal dysfunction, multiple myeloma, or other paraproteinemias, sickle cell anemia, diabetes mellitus, polyuria, oliguria, hyperuricemia, as well as in newborns, children, and elderly patients.

Dietary suggestions- If there are no specific instructions from the doctor, a normal diet can be followed. Confirm adequate fluid intake. However, the patient should abstain from food for 2 hours before the examination.

Hypersensitivity- In patients with a predisposition to allergies, known hypersensitivity to iodinated contrast media, and a history of asthma, premedication with antihistamines and/or corticosteroids may be considered to prevent possible anaphylactoid reactions.

Severe cutaneous adverse reactions- Severe cutaneous adverse reactions (SCARs), including Stevens-Johnson syndrome (SJS), toxic epidermal necrolysis (TEN), generalized acute pustular psoriasis (GAPP), and drug reaction with eosinophilia and systemic symptoms (DRESS), which can be fatal or potentially fatal, have been reported in patients who received iodinated contrast media intravascularly. At the time of administration, patients should be advised of the signs and symptoms, and closely monitored for the appearance of cutaneous reactions. If signs and symptoms suggest the onset of these reactions, administration of Iomeron should be stopped immediately. If a patient has developed a severe reaction such as SJS, TEN, GAPP, or DRESS with the use of Iomeron, Iomeron should not be administered to that patient at any time.

Anxiety- States of excitement, anxiety, and pain can be a cause of secondary effects or can intensify reactions related to the contrast medium. In these cases, a sedative may be administered.

Concomitant treatments- Consider interrupting treatment with drugs that reduce the convulsive threshold for up to 24 hours after the procedure, in cases of intrathecal use, and in patients with disorders of the blood-brain barrier (see "Neurological symptoms").

• Regarding the procedure:

Coagulation, catheterism- A property of non-ionic contrast media is their minimal interference with physiological functions. As a consequence, non-ionic contrast media have, in vitro, a lower anticoagulant activity than ionic contrast media. Medical and paramedical personnel performing vascular catheterism should be informed of this and should pay particular attention to angiographic technique. Non-ionic contrast media should not come into contact with blood in the syringe, and catheters should be cleaned frequently to minimize the risk of thromboembolism related to the procedure.

Patient observation- Whenever possible, intravascular administration of contrast media should be performed with the patient lying down. The patient should be kept under observation for at least 30 minutes after administration.

Test for sensitivity- A test for sensitivity is practically useless, as the appearance of severe or fatal reactions due to contrast media cannot be predicted by such a test.

Risk of inflammation and extravasation- It is recommended to exercise caution during the injection of contrast media to avoid extravasation.

Warnings

• Common to all forms of administration

Considering the possible severe side effects, the use of iodinated organic contrast media should be limited to specific needs for contrastographic explorations.

This need should be considered according to the patient's clinical conditions, especially in relation to cardiovascular, urinary, and hepatobiliary pathologies.

Iodinated contrast media for angiocardiographic explorations should be used in hospitals or clinics with competent personnel and necessary equipment for emergency care. In centers where common diagnostic examinations requiring iodinated contrast media are performed, the radiology services where these examinations are performed should have therapeutic measures and resuscitation equipment confirmed by experience to be suitable (Ambu balloon, oxygen, antihistamines, vasoconstrictors, etc.).

Use in:

Pediatric population- Newborns and especially neonates are particularly susceptible to electrolyte imbalances and hemodynamic alterations. Attention should be paid to the doses to be used, the procedure technique, and the patient's condition.It may be observed that hypothyroidism or transient thyroid suppression occurs after exposure to iodinated contrast media. Particular attention should be paid to pediatric patients under 3 years of age, as an episode of low thyroid activity during the first years of life may be detrimental to motor, auditory, and cognitive development and may require temporary substitution treatment with T4. The incidence of hypothyroidism in patients under 3 years of age exposed to iodinated contrast media has been reported to be between 1.3% and 15%, depending on the age of the subjects and the dose of the iodinated contrast medium, and is more frequently observed in neonates and premature infants. Thyroid function should be evaluated in all pediatric patients under 3 years of age after exposure to iodinated contrast media. If hypothyroidism is detected, the need for treatment should be considered, and thyroid function should be monitored until it normalizes.

Elderly patients-Patients of advanced age should be considered to be at special risk of reactions due to excessive dosing of the contrast medium. The frequent association of neurological disorders and vascular pathologies constitutes an aggravating factor.

Patients with particular pathological conditions

• Administration via intraarterial and intravenous routes

Use in patients with special pathological conditions

Renal impairment- In patients with compromised renal function, administration of contrast media may cause episodes of renal insufficiency. Preventive measures include: identifying patients at high risk; ensuring adequate hydration before administration of the contrast medium, preferably maintaining intravenous infusion before, during the procedure, and until the contrast medium has been eliminated by the kidneys; avoiding, if possible, administration of nephrotoxic drugs and subjecting the patient to major surgical interventions or procedures such as renal angioplasty until the contrast medium has been completely eliminated; postponing a new examination with contrast medium until renal function returns to pre-examination levels. Patients on dialysis can receive contrast media, such as iomeprol, which are dialyzable without difficulty.

Diabetes mellitus- The presence of renal damage in diabetic patients is one of the factors that predisposes to renal dysfunction as a result of contrast medium administration.

The renal impairment may cause lactic acidosis in diabetic patients with renal damage treated with biguanides (metformin). Treatment with biguanides should be suspended before intraarterial administration of a contrast medium with first-pass renal exposure, in patients with an eGFR of less than 30 ml/min/1.73 m2who receive a contrast medium via the intravenous route or a contrast medium via the intraarterial route with second-pass renal exposure, or in patients with acute renal injury, and should only be resumed after 48 hours, provided that renal function has not changed significantly.

Phaeochromocytoma- These patients may develop severe hypertensive crises (rarely uncontrolled) after using intravascular contrast media during radiological procedures.

In patients with phaeochromocytoma, premedication with alpha-blockers is recommended due to the risk of hypertensive crises.

Myasthenia gravis-The administration of iodinated contrast media may exacerbate the symptoms and signs of myasthenia.

Cardiovascular disease and pulmonary hypertension- There is a high risk of severe reactions in patients with severe cardiovascular disease, particularly those with heart failure and coronary artery disease. Intravascular injection of contrast media may cause pulmonary edema in patients with manifest or incipient heart failure, while administration of the contrast medium in cases of pulmonary hypertension and valvular disease may favor hemodynamic alterations. The appearance of ECG signs of ischemia and severe arrhythmias is more common in older patients and those with pre-existing cardiovascular disease: their frequency and severity appear to be related to the severity of cardiovascular disease.

Neurological symptoms- Particular attention should be paid when administering a contrast medium to patients with acute cerebral infarction, intracranial hemorrhage, and alterations of the blood-brain barrier, cerebral edema, or acute demyelination. The presence of intracranial tumors or metastases and a history of epilepsy may increase the likelihood of seizures. Administration of contrast media may exacerbate neurological symptoms due to cerebrovascular degenerative, ischemic, inflammatory, or neoplastic pathologies. These patients have a higher risk of transient neurological complications. Intravascular injections of contrast media may cause angiospasm and episodes of cerebral ischemia.

Contrast-induced encephalopathy– Iomeprol-induced encephalopathy has been reported.

Contrast-induced encephalopathy may manifest with symptoms and signs of neurological dysfunction such as headache, visual disturbances, cortical blindness, confusion, seizures, loss of coordination, hemiparesis, aphasia, unconsciousness, coma, and cerebral edema in the minutes to hours following administration of iomeprol, and usually resolves within days.

The product should be used with caution in patients with diseases affecting the integrity of the blood-brain barrier (BBB), which may cause increased permeability of the contrast medium through the BBB and increase the risk of encephalopathy. If encephalopathy induced by contrast is suspected, administration of iomeprol should be stopped and appropriate medical control initiated.

Alcoholism- It has been demonstrated experimentally and clinically that acute or chronic alcoholism increases the permeability of the blood-brain barrier. It facilitates the passage of iodated agents into the cerebral tissue that can produce CNS disorders. It should be taken into account that there may be a reduction in the convulsive threshold in alcoholics.

Toxicomania- Patients with a history of substance abuse require particular attention due to the possible reduction in the convulsive threshold.

It is recommended to perform fluoroscopy to minimize extravasation during injection.

Overdose

In the event that the responsible physician diagnoses an accidental intravascular overdose of the contrast medium, the patient's hydration and electrolyte balance should be monitored and corrected if necessary. In this situation, renal function should be monitored for at least 3 days.
