1. What Iomeron is and what it is used for

Medicinal product intended exclusively for diagnostic purposes.
Iomeronis a sterile aqueous solution of iomeprol in concentrations ranging from 200 to 400 mg iodine/ml.
The active substance of the medicine is iomeprol - a triiodinated, non-ionic, water-soluble contrast agent used in radiological diagnosis of various body regions.
After intravenous administration of the medicine Iomeron, most of it is excreted in the urine within the first 24 hours, and small amounts are excreted between 24 and 38 hours after administration.

2. Important information before using Iomeron

When not to use Iomeron:

Do not administer the medicine Iomeron:

• if the patient is allergic to the active substance or any of the other ingredients of this medicine (listed in section 6),
• if there is a repeat myelography, due to the possibility of contrast agent overdose.

Warnings and precautions

Before starting treatment with the medicine Iomeron, you should discuss it with your doctor or nurse.

• if the patient is an allergic person, has asthma and especially if they are taking blood pressure regulating medications (beta-adrenolytics).
• if the patient has thyroid function disorders.
• if the patient has ever experienced severe rash or skin peeling after taking an iodine contrast agent, blistering and (or) mouth ulcers after receiving an iodine contrast agent.

Pregnancy and breastfeeding

Since, if possible, exposure to radiation should be avoided during pregnancy,
the benefit of performing an X-ray examination with or without a contrast agent should be carefully considered in the context of possible risk.
If the patient is pregnant and has received Iomeron during pregnancy, it is recommended to monitor the thyroid function of the child after birth.
Similarly, X-ray examination with contrast agent should be avoided in breastfeeding women. Contrast agents are excreted in small amounts in the milk of breastfeeding women. Based on current experience, the occurrence of side effects in the breastfed infant is unlikely. Breastfeeding can be continued after the examination with the medicine Iomeron.

Elderly

Due to the deterioration of physiological functions in the elderly, there is a particular risk of side effects, especially when large doses of contrast agents are used.

Children

After administration of the medicine Iomeron, both in children and adults, thyroid function disorders may occur. Infants may also be exposed through their mother during pregnancy. It may be necessary for the doctor to perform thyroid function tests before and (or) after administration of the medicine Iomeron.

Hypersensitivity to iodine contrast agents

Diagnosed hypersensitivity or previous reaction to iodine contrast agents also increases the risk of recurrence of a severe reaction to non-ionic agents. In these patients, it is recommended to administer glucocorticoids and antihistamines to prevent another reaction.

Predisposition to allergic reactions

Side effects of iodine contrast agents occur more frequently in patients with a history of allergy: hay fever, urticaria, and food allergy.

Asthma

Patients using beta-adrenolytics, especially those with asthma, may have a lower threshold for bronchospasm and may respond less to beta-agonist and adrenaline treatment, which may require the use of higher doses of adrenaline.

Thyroid function and thyroid function tests

Small amounts of free inorganic iodine that may be present in contrast agents can affect thyroid function. This effect is more pronounced in patients with latent or overt hyperthyroidism or goiter. There have been reports of hyperthyroidism or even thyroid crisis after administration of iodine contrast agents.

Renal impairment

Previous renal impairment may predispose to the occurrence of acute renal dysfunction after administration of contrast agents. Preventive measures include:

• identification of patients at high risk;
• ensuring adequate hydration before administration of contrast agents, it is recommended to maintain intravenous fluid infusion before and during the procedure until complete excretion of the contrast agent by the kidneys;
• avoiding, whenever possible, the use of nephrotoxic drugs or performing extensive procedures or procedures such as renal artery angioplasty until complete excretion of the contrast agent;
• delaying the next examination with contrast agent until renal function returns to pre-examination levels. In dialyzed patients, contrast agents such as iomeprol can be administered before dialysis.

Diabetes

Diabetic nephropathy is one of the factors that predispose to the development of renal function disorders after administration of contrast agents. Biguanide derivatives (e.g., metformin) can accelerate the development of lactic acidosis.

Pheochromocytoma

In order to reduce the risk of hypertensive crisis, it is recommended to use alpha-adrenergic blockers in these patients.
Myasthenia gravis
The administration of iodine contrast agents can exacerbate the symptoms of the disease.

Severe cardiovascular disease

The risk of severe reactions in patients with serious heart disease, especially in the case of heart failure and coronary artery disease, is increased.
Intravascular injection of a contrast agent can accelerate the onset of pulmonary edema in patients with overt or impending heart failure. The administration of a contrast agent in the case of pulmonary hypertension and valvular defects can lead to significant hemodynamic changes.

CNS disorders

Particular attention should be paid to the intravascular administration of contrast agents in patients with acute cerebral ischemia, acute intracranial hemorrhage, conditions with blood-brain barrier disruption, cerebral edema, and acute demyelination.
The presence of intracranial tumors or metastases and a history of epilepsy may increase the likelihood of seizures.
Neurological symptoms caused by concomitant degenerative, inflammatory, or neoplastic changes may worsen after administration of a contrast agent.
Intravascular injection of a contrast agent can cause vascular spasm and resulting ischemia symptoms.
During imaging or shortly after, the patient may experience a transient cerebral disturbance, called encephalopathy. If the patient experiences any symptoms related to this disorder, as described in section 4, they should immediately inform their doctor.

Alcoholism

It has been proven that both experimentally and clinically, acute and chronic alcoholism leads to increased permeability of the blood-brain barrier, facilitating the penetration of iodine contrast agents into brain tissue, potentially leading to CNS disorders. Due to the possibility of lowering the seizure threshold, caution should be exercised in individuals addicted to alcohol.

Drug dependence, drug addiction

Caution should be exercised in individuals dependent on drugs or narcotics, due to the possibility of lowering the seizure threshold.

States of excitement

States of severe anxiety, excitement, and pain can cause or exacerbate side effects caused by the administration of contrast agents.

Extravasation

Caution should be exercised when injecting a contrast agent to avoid extravasation.

Particular caution should be exercised when using the medicine Iomeron

In connection with the use of the medicine Iomeron, severe skin reactions have been reported, including Stevens-Johnson syndrome (SJS), toxic epidermal necrolysis (TEN), acute generalized exanthematous pustulosis (AGEP), and drug reaction with eosinophilia and systemic symptoms (DRESS). If any symptoms related to severe skin reactions described in section 4 are observed, medical help should be sought immediately.

Iomeron and other medicines

The doctor will consider discontinuing treatment with medications that lower the seizure threshold. Treatment will be resumed 24 hours after the procedure.
Antiepileptic therapy should not be discontinued, and medications should be administered in optimal doses.
Biguanide derivatives (e.g., metformin) can accelerate the development of lactic acidosis. As a precaution, it is recommended to discontinue the use of biguanide derivatives during or 48 hours before the examination with contrast agents and resume their use only after checking renal function and ensuring it has returned to its initial state.
Increased risk of side effects, especially delayed ones (rash, erythema, fever, flu-like symptoms), occurs in patients treated with interleukin-2 (IL-2) and interferon.

Thyroid function tests

The uptake of radioactive isotopes in diagnostic tests of thyroid function disorders is reduced for a period of up to 16 days after administration of iodine contrast agents.
Thyroid test results independent of iodine levels, i.e., T3, T4 levels, are not changed. All tests whose results depend on iodine levels should be performed before contrast examination. The above observations do not depend on clinical symptoms.

Laboratory tests

High concentrations of contrast agents in serum and urine can affect the results of laboratory tests for bilirubin, protein, or inorganic substances (e.g., iron, copper, calcium, phosphates).

Driving and operating machinery

The effect on the ability to drive and operate machinery is not known.

3. How to use Iomeron

Details on dosing can be found at the end of the leaflet in the section Information for healthcare professionals or healthcare workers. Diagnostic tests using contrast agents should be performed by appropriately trained medical personnel.

Overdose

Overdose can lead to life-threatening side effects, mainly due to the effect on the respiratory and cardiovascular systems. Treatment of overdose focuses on maintaining vital functions and symptomatic therapy. Dialysis or hemodialysis can also be used.
In case of overdose after intravascular administration, it is especially important to carefully monitor for CNS disorders. Symptoms include: ascending enhancement of deep reflexes, tonic-clonic seizures, generalized seizures, increased body temperature, stupor, respiratory arrest.

4. Possible side effects

Like any contrast agent, Iomeron can cause side effects, although they do not occur in everyone.
Side effects are usually mild to moderate and transient. However, severe and life-threatening reactions leading to death have also been reported. Reactions usually occur within a few minutes of administration but can occur much later.
Anaphylaxis (anaphylactoid/anaphylactic reactions) manifests in different ways, very rarely in one patient showing all possible symptoms. Usually within 1 to 15 minutes (rarely longer than 2 hours) the patient complains of malaise, excitement, heat strokes, feeling of heat, increased sweating, dizziness, increased lacrimation, nasal congestion, palpitations, paresthesia, itching, feeling of pulsation in the head, sore throat, and feeling of constriction in the throat, difficulty swallowing, coughing, sneezing, urticaria, erythema, mild local edema, angioedema, dyspnea caused by tongue and laryngeal edema and (or) its spasm, which manifests as wheezing and bronchospasm.
There have also been reports of nausea, vomiting, abdominal pain, and diarrhea.
These reactions, which occur regardless of dose and route of administration, can be the first symptoms of circulatory failure.
Administration of the contrast agent should be stopped immediately and, if necessary, appropriate treatment should be administered intravenously.
Severe reactions from the cardiovascular system, such as vasodilation with a drop in blood pressure, tachycardia, dyspnea, excitement, cyanosis, loss of consciousness progressing to cardiac arrest and respiratory arrest, can lead to death. These reactions can occur quickly and require full and intensive cardiopulmonary resuscitation (restoration of cardiovascular and respiratory function).
Primary circulatory collapse may occur as the only and (or) initial reaction without additional respiratory symptoms or other symptoms mentioned earlier.

Children

Experience with the use of iomeprol in children is limited. The safety profile of iomeprol is similar in children and adults. In children under 3 years of age, transient hypothyroidism may occur.

Side effects after intravascular administration

Adults

The most commonly reported side effects after intravascular administration of iomeprol are: headache, dizziness, nausea, vomiting, and back pain. These reactions are mild to moderate and transient. In rare cases, headache may last for several days. Most side effects occur within 3-6 hours after administration, depending on the rate of distribution of the contrast agent from the injection site to the vessels. Most reactions occur within 24 hours after administration.

Very common (occurring in more than 1 in 10 patients):

headache.

Common (occurring in 1 to 10 out of 100 patients):

dizziness, hypertension, nausea, vomiting, back pain, pain in the limbs, reaction at the injection site*.

Uncommon (occurring in 1 to 10 out of 1,000 patients):

loss of consciousness, paralysis, paresthesia, numbness, hypotension, sudden flushing, increased sweating, itching, stiffness of muscles and joints, neck pain, feeling of heat, fever.

Frequency not known:

anaphylactic reaction, seizures, rash.
* Reactions at the injection site include pain at the injection site and edema.

Children

The safety profile of this medicine in children is similar to that in adults.
No side effects have been reported after intravascular administration of iomeprol in children.

Side effects after administration into body cavities

After administration of iodine contrast agents into body cavities, contrast agents are slowly absorbed from the injection site into the circulatory system and then excreted by the kidneys.
An increase in amylase levels occurs frequently after endoscopic retrograde cholangiopancreatography (ERCP). Rare cases of pancreatitis have been reported.
Reactions reported during arthrography and fistulography are related to irritation symptoms, which occur in previously inflamed tissues.
Hypersensitivity reactions are rare, mild, or in the form of dermatitis. However, severe anaphylactic reactions cannot be ruled out.
As with other iodine contrast agents, after hysterosalpingography (radiological examination aimed at visualizing the uterine cavity and fallopian tubes), pelvic pain and malaise may occur.

Reporting side effects

If you experience any side effects, including any not listed in this leaflet, you should tell your doctor or pharmacist.
Side effects can be reported directly to the Department of Adverse Reaction Monitoring of Medicinal Products, Medical Devices, and Biocidal Products, Al. Jerozolimskie 181C, 02-222 Warsaw, tel.:

Dosage

The recommended doses for adults have been calculated for an average body weight of 70 kg. Each time before administration, the dose should be adjusted to the patient's current body weight and other relevant factors (e.g., clinical condition).
The recommended doses for newborns, infants, and children are given per single injection/kg body weight and are as follows:
= in accordance with body weight and age
= do not exceed 250 ml. The volume of a single injection depends on the vascular area to be examined,
= do not exceed 350 ml
= do not exceed 4500 mg of iodine and a concentration above 300 mg I/ml when administered intravascularly
= newborns 0-27 days old
= infants from 28 days to 12 months old
= includes children and adolescents (1-17 years old)

Instructions for use

Contrast agents administered intravascularly and intracavally should have body temperature during injection.
Before administration, check for visible mechanical contamination and changes in the color of the medicine, if the packaging type allows.
Never mix other medicinal products with contrast agents.
The contrast agent is drawn up from the packaging under sterile conditions and with a sterile syringe.
Sterile conditions and technique should be maintained when performing intracavitary injection, intravascular administration, using catheters, and guidewires.
Once opened, packaging must be used immediately. The rubber stopper should never be punctured more than once.
It is recommended to use suitable cannulas for piercing the stopper and drawing up the contrast agent from the packaging.
Contrast agents in packaging intended for multiple use and with a capacity of 500 ml should be used with appropriate injection devices. After the examination, all parts intended for single use should be discarded. The instructions provided by the manufacturer of the injection device should be followed.
Iomeprol, like other contrast agents, may react with metal surfaces containing copper, e.g., brass, so it is recommended to avoid using equipment made of this type of material.
Contraindications to intracavitary administration:
Repeat myelography is contraindicated due to the possibility of contrast agent overdose.

Special warnings and precautions for use

Diagnostic tests using contrast agents should be performed by appropriately trained medical personnel (especially in the treatment of anaphylactic shock and maintenance of vital functions).

General precautions for use in relation to the patient

Hydration

Patient should be well-hydrated, and any significant water-electrolyte imbalance should be corrected before and after administration of the contrast agent. Patients with severe renal, hepatic, or cardiac impairment, multiple myeloma, or other paraproteinemia, hemolytic anemia, diabetes, polyuria, oliguria, hyperuricemia, infants, elderly patients, and patients with severe systemic disease should not be exposed to dehydration. Caution should be exercised in hydrated patients whose condition may worsen due to the administration of excessive amounts of fluid, including congestive heart failure.

Dietary recommendations

Unless the doctor has prescribed otherwise, a normal diet can be followed on the day of the examination. Adequate fluid intake should be ensured before and after intravascular administration.

Allergy test

In patients with suspected or existing hypersensitivity to contrast agents, it is not recommended to perform an allergy test, as severe or fatal reactions to contrast agents are unpredictable based on allergy test results.

Hypersensitivity

In patients with a tendency to allergies, hypersensitivity reactions to iodine contrast agents, and (or) asthma, it is recommended to administer antihistamines and (or) glucocorticoids to reduce the risk of pseudo-anaphylactic reactions.

Anxiety

Severe anxiety, excitement, and pain can cause or exacerbate side effects caused by the administration of contrast agents.

Newborns, infants, children

Infants (<1 year old), especially newborns, are particularly susceptible to electrolyte imbalance and hemodynamic changes. attention should be paid planned dosing, details of the procedure, patient's health status.< p>

General precautions for use in relation to the procedure

Intracavitary administration

As with other contrast agents, Iomeronshould be administered with particular caution to patients with increased intracranial pressure or suspected tumor, abscess, or hemorrhage in the brain. In patients with a history of seizures, antiepileptic medications should be used before and after myelographic examination.

Catheterization

Non-ionic contrast agents show weaker anticoagulant activity in vitro than ionic agents. Medical personnel performing catheterization should be informed about this. The angiographic procedure and catheter flushing should be performed very carefully to minimize the risk of thrombosis and embolism associated with the procedure. To maintain catheter patency, it can be flushed with a physiological saline solution (if necessary with added heparin).

Patient monitoring

Intravascular administration - contrast agents should, if possible, be administered to a patient in a supine position. The patient should be monitored for at least 30 minutes after administration of the contrast agent.
Intracavitary administration - after completion of direct administration to the cervical or lumbar region, the head of the bed should be elevated (about 45°) for about 2 minutes to allow the contrast agent to fill the lower parts of the spinal canal. During the first hours after the examination, the patient should avoid excessive, sudden movements and remain under special observation. They should then lie on their back with their head elevated.
Administration into the basal cisterns or ventricles - direct administration is not recommended when using conventional radiography without computer enhancement.
The label torn off from the vial or bottle should be attached to the patient's chart to allow proper registration of the administered medicinal product. The dose should also be recorded.
