This medication is solely for diagnostic use.

Iomeron belongs to the 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 head and body, peripheral phlebography, digital subtraction phlebography, digital subtraction arteriography, and myelography.In children from 0 to 18 years for intravenous urography, computed tomography (CT) of the head and body, digital subtraction phlebography, and peripheral arteriography.

No use Iomeron 250 mg Iodo/ml solución inyectable

Genital tract investigations are contraindicated in case of suspected pregnancy or confirmed pregnancy and in case of acute inflammation.

The immediate repetition of Iomeron administration in case of a technique failure is contraindicated in myelography.

Warnings and precautions

It is recommended to perform fluoroscopy to minimize extravasation during 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 in association 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 250 mg Iodo/ml injectable solution.

Children

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

Other medications and Iomeron 250 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 studies, 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 Iomeron 250 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 abstain from eating food in the two hours prior to 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

You should 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

Iodinated contrast media are poorly excreted in breast milk, and it is remote that the infant may suffer any harm.

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 overall condition you present, as well as the technique used.

If you use more Iomeron 250 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.

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

This information is intended only for healthcare professionals:

Iomeron 250 mg Iodo/ml is an injectable solution for intravenous, intraarterial, and intratecal administration.

Whenever possible, intravascular administration of contrast media should be done with the patient lying down. Keep the patient 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.

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 alteration of the hydro-electrolyte balance should be corrected. Before the medical examination, ensure adequate hydration, especially in patients with severe renal dysfunction, multiple myeloma, other paraproteinemias, sickle cell anemia, diabetes mellitus, polyuria, oliguria, hyperuricemia, as well as in neonates, children, and elderly patients.

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

Hypersensitivity- In patients with a predisposition to allergies, with known hypersensitivity to iodinated contrast media, and with 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 exanthematous pustulosis (GEP), 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 warned 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 suspended immediately. If a patient has developed a severe reaction such as SJS, TEN, GEP, 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 up to 24 hours after the procedure, in case 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 the minimal interference with physiological functions. As a consequence, non-ionic contrast media have, in vitro, a lower anticoagulant activity than ionic contrast media. The medical and paramedical personnel performing vascular catheterism should be informed of this and should pay particular attention to the 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 done with the patient lying down. Keep the patient under observation for at least 30 minutes after administration.

Sensitivity test- A sensitivity test is practically useless, as severe or fatal reactions due to contrast media cannot be predicted with 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 secondary effects, the use of organic iodine 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.

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

Use in:

Pediatric population- Children under one year of age, 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.Possible thyroid hypofunction or transient thyroid suppression may be observed 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 pediatric 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- Elderly patients should be considered 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

• Intravenous and intraarterial administration

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 important 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.

Renal impairment may cause lactic acidosis in diabetic patients with renal damage treated with biguanides (metformin). To prevent it, treatment with biguanides should be suspended in the following cases: 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 by intravenous route or a contrast medium by intraarterial route with second-pass renal exposure, or in patients with acute renal injury, and only should 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- Administration of iodinated contrast media may exacerbate the symptoms of myasthenia.

Cardiac 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 cardiac disease: their frequency and severity appear to be related to the severity of the cardiac 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 degenerative, ischemic, inflammatory, or neoplastic cerebrovascular pathologies.These patients have a higher risk of transient neurological complications.Intravascular injections of contrast media may cause angiospasm and episodes of cerebral ischemia.

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 iodinated agents into the cerebral tissue, which can produce CNS disorders. It should be noted that there may be a reduction in the epileptic threshold in alcoholics.

Contrast-induced encephalopathy– Contrast-induced encephalopathy has been reported with the use of iomeprol.

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 suspended and appropriate medical control initiated.

Toxicomania- Patients with toxicomania require particular attention due to the possible reduction of the convulsive threshold.

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

Overdose

In the event of an intravascular accidental overdose of the contrast medium diagnosed by the responsible physician, 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 three days.

In the event of an accidental intrathecal overdose, the patient should be closely monitored for at least 24 hours to detect signs and symptoms of CNS disorders. These signs may include increased hyperreflexia or tonic-clonic spasms, and even generalized seizures, hyperthermia, stupor, and respiratory depression.
