Special Senses:
Smell, taste, and vision alteration. 1 ) Pediatric patients experienced similar adverse reactions. gov/medwatch . 1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.
Iodixanol is often associated with sensations of discomfort, warmth or pain. In a subgroup of 1,259 patients; 30% who received iodixanol or a comparator had application site discomfort, pain, warmth or cold. Iodixanol had a trend toward fewer patient reports of moderate or severe pain or warmth.
Pain was reported in 2% of patients receiving iodixanol and 10% of patients receiving a comparator. Heat was reported in 29% of patients receiving iodixanol and 51% of patients receiving a comparator. Table 3 shows the incidence of events reported in blinded, controlled clinical studies of iodixanol in a total of 1,244 adult patients.
5% of patients. One or more adverse events were reported in 20% of patients during the study period (24 to 72 hours). In a 757 patient subgroup, the number of women reporting adverse events was 83/299 (28%) and the number of men was 77/458 (16%).
8% of men reported chest pain. 5% of the 1,244 patients. 2 Post-marketing Experience The following additional adverse reactions have been identified during post approval use of iodixanol. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to exposure.

g. g. 3 Pediatric Adverse Reactions The overall character, quality, and severity of adverse reactions in pediatric patients is similar to that reported in adult patients from post marketing surveillance and other information. Additional safety data was obtained in studies of iodixanol in 459 pediatric patients.
A total of 26 patients ranged in age from birth to <29 days, 148 ranged from 29 days to 2 years, 263 from 2 to <12 years, and 22 from 12 to 18 years. A total of 252 (55%) of the patients were male.
The racial distribution was:
Caucasian-81%, Black-14%, Oriental-2%, and other or unknown-4%. The proportion of patients undergoing an intra-arterial procedure by age was: 92 % (<29 days), 55% (29 days to 6 months), and 29 % (>6 months). In these studies, adverse events were numerically higher in pediatric patients less than one year of age compared to older pediatric patients.
In pediatric patients who received intravenous injections of iodixanol for computerized tomography or excretory urography, a concentration of 270 mg Iodine/mL was used in 144 patients, and a concentration of 320 mg Iodine/mL in 154 patients.
All patients received one intravenous injection of 1 mL/kg to 2 mL/kg. In pediatric patients who received intra-arterial and intracardiac studies, a concentration of 320 mg Iodine/mL was used in 161 patients. Twenty-two patients were <29 days of age; 78 were 29 days to 2 years of age; and 61 were over 2 years.
Most of these pediatric patients received initial volumes of 1 mL/kg to 2 mL/kg and most patients received a maximum of 3 injections.
Use the lowest necessary dose of iodixanol in patients with renal impairment. Adequately hydrate patients prior to and following iodixanol administration. Do not use laxatives, diuretics, or preparatory dehydration prior to iodixanol administration.
4 Cardiovascular Adverse Reactions Life-threatening or fatal cardiovascular reactions including hypotension, shock, cardiac arrest have occurred with the use of iodixanol. Most deaths occur during injection or five to ten minutes later, with cardiovascular disease as the main aggravating factor.
Cardiac decompensation, serious arrhythmias, and myocardial ischemia or infarction can occur during coronary arteriography and ventriculography. 01%). Use the lowest necessary dose of iodixanol in patients with congestive heart failure and always have emergency resuscitation equipment and trained personnel available.
Monitor all patients for severe cardiovascular reactions. 5 Thromboembolic Events Angiocardiography Serious, rarely fatal, thromboembolic events causing myocardial infarction and stroke can occur during angiocardiography procedures with both ionic and nonionic contrast media.
During these procedures, increased thrombosis and activation of the complement system occurs. Risk factors for thromboembolic events include: length of procedure, catheter and syringe material, underlying disease state, and concomitant medications.
To minimize thromboembolic events, use meticulous angiographic techniques, and minimize the length of the procedure. Avoid blood remaining in contact with syringes containing iodinated contrast agents, which increases the risk of clotting.
Avoid angiocardiography in patients with homocystinuria because of the risk of inducing thrombosis and embolism. 6 Extravasation and Injection Site Reactions Extravasation of iodixanol injection may cause tissue necrosis and/or compartment syndrome, particularly in patients with severe arterial or venous disease.
Ensure intravascular placement of catheters prior to injection. Monitor patients for extravasation and advise patients to seek medical care for progression of symptoms. 7 Thyroid Storm in Patients with Hyperthyroidism Thyroid storm has occurred after the intravascular use of iodinated contrast agents in patients with hyperthyroidism, or with an autonomously functioning thyroid nodule.
Evaluate the risk in such patients before use of iodixanol. 8 Thyroid Dysfunction in Pediatric Patients 0 to 3 Years of Age Thyroid dysfunction characterized by hypothyroidism or transient thyroid suppression has been reported after both single exposure and multiple exposures to iodinated contrast media (ICM) in pediatric patients 0 to 3 years of age.
Younger age, very low birth weight, prematurity, underlying medical conditions affecting thyroid function, admission to neonatal or pediatric intensive care units, and congenital cardiac conditions are associated with an increased risk of hypothyroidism after ICM exposure.
Pediatric patients with congenital cardiac conditions may be at the greatest risk given that they often require high doses of contrast during invasive cardiac procedures. An underactive thyroid during early life may be harmful for cognitive and neurological development and may require thyroid hormone replacement therapy.
After exposure to ICM, individualize thyroid function monitoring based on underlying risk factors, especially in term and preterm neonates. 9 Hypertensive Crisis in Patients with Pheochromocytoma Hypertensive crisis has occurred after the use of iodinated contrast agents in patient with pheochromocytoma.
Monitor patients when administering iodixanol if pheochromocytoma or catecholamine-secreting paragangliomas are suspected. Inject the minimum amount of contrast necessary, assess the blood pressure throughout the procedure, and have measures for treatment of a hypertensive crisis readily available.
10 Sickle Cell Crisis in Patients with Sickle Cell Disease Iodinated contrast agents when administered intravascularly may promote sickling in individuals who are homozygous for sickle cell disease. Hydrate patients prior to and following iodixanol administration and use iodixanol only if the necessary imaging information cannot be obtained with alternative imaging modalities.
11 Severe Cutaneous Adverse Reactions Severe cutaneous adverse reactions (SCAR) may develop from 1 hour to several weeks after intravascular contrast agent administration. These reactions include Stevens-Johnson syndrome and toxic epidermal necrolysis (SJS/TEN), acute generalized exanthematous pustulosis (AGEP) and drug reaction with eosinophilia and systemic symptoms (DRESS).
Reaction severity may increase and time to onset may decrease with repeat administration of contrast agents; prophylactic medications may not prevent or mitigate severe cutaneous adverse reactions. Avoid administering iodixanol to patients with a history of a severe cutaneous adverse reaction to iodixanol.
