Warnings
Black Box Warnings
Administer procedure at facilities where staff is familiar with the recognition and treatment of allergic reactions
When administering large doses use caution in patients with renal impairment or concurrent renal/hepatic impairment
Neurologic events including paralysis following cerebral arteriography, arteriography of blood vessels , and spinal arteriography, reported
Myocardial infarctions and stroke reported with angiographic procedures
Thyroid storm reported with the use of iodinated contrast media
Use caution in patients with multiple myeloma and pheochromocytoma
Serious adverse events reported with inadvertent administration of iodinated contrast media intrathecally
Inadvertent intrathecal administration may cause death, convulsions, cerebral hemorrhage, coma, paralysis, arachnoiditis, acute renal failure, cardiac arrest, seizures, rhabdomyolysis, hyperthermia, and brain edema
Contraindications
Not for intrathecal use (may cause death, convulsions, cerebral hemorrhage, coma, paralysis, ARF)
Symptomatic hyperthyroidism
Cautions
Inhibits blood coagulation
Caution in severe renal impairment, combined renal/hepatic disease, severe thyrotoxicosis, myelomatosis, anuria, pheochromocytoma, sickle cell, CHF, chronic alcoholism, severe arterial/venous disease
May cause renal failure in patients with advanced vascular disease, diabetes; should be well hydrated before/after procedure; do not use laxatives, diuretics, or preparatory dehydration prior to administering product
Obtain a history of allergy, hypersensitivity, or prior hypersensitivity reactions to iodinated contrast agents; always have emergency resuscitation equipment and trained personnel available and monitor all patients for hypersensitivity reactions
Allergies (bronchial asthma, hay fever, food allergies) reported
Premedication with antihistamines or corticosteroids to avoid or minimize possible allergic reactions should be considered; reports indicate that such pretreatment does not prevent serious life-threatening reactions, but may reduce both their incidence and severity
General anesthesia may be indicated in the performance of some procedures in selected patients; however, a higher incidence of adverse reactions has been reported in these patients
In angiographic procedures, the possibility of dislodging plaques or damaging or perforating the vessel wall should be considered during catheter manipulations and contrast medium injection; test injections to ensure proper catheter placement are suggested
Angiography should be avoided whenever possible in patients with homocystinuria because of risk of inducing thrombosis and embolism
Patients with congestive heart failure should be observed for several hours following procedure to detect delayed hemodynamic disturbances which may be associated with transitory increase in circulating osmotic load
Extreme caution during injection of contrast medium is necessary to avoid extravasation; this is especially important in patients with severe arterial or venous disease
Selective coronary arteriography should be performed only in selected patients and those in whom expected benefits outweigh procedural risk; inherent risks of angiocardiography in patients with chronic pulmonary emphysema must be weighed against necessity for performing this procedure
Fatal, thromboembolic events causing myocardial infarction and stroke can occur during angiographic procedures; to minimize thromboembolic events use meticulous angiographic technique; avoid blood remaining in contact with syringes containing the product, which increases risk of clotting; avoid angiocardiography in patients with homocystinuria because of risk of inducing thrombosis and embolism
Contraindicated in patients with symptomatic hyperthyroidism; thyroid storm reported following intravascular use of iodinated radiopaque agents in patients with hyperthyroidism or with autonomously functioning thyroid nodule; evaluate risk in patients before using product
Hypertensive crisis has occurred after use of iodinated radiopaque contrast agents in patient with pheochromocytoma; closely monitor patients when administering product if pheochromocytoma or catecholamine-secreting paraganglioma is suspected; inject minimum amount of product necessary and have measures for treatment of hypertensive crisis readily available
Iodinated contrast agents may promote sickling in individuals who are homozygous for sickle cell disease; hydrate patients prior to and following product administration; use product only if necessary imaging information cannot be obtained with alternative imaging modalities, and inject minimum amount necessary
Severe cutaneous adverse reactions(SCAR), including Stevens-Johnson syndrome and toxic epidermal necrolysis (SJS/TEN), acute generalized exanthematous pustulosis (AGEP) and drug reaction with eosinophilia and systemic symptoms (DRESS), may develop from 1 hr to several weeks after intravascular contrast agent administration; reaction severity may increase and time to onset may decrease with repeat administration of contrast agent; prophylactic medications may not prevent or mitigate severe cutaneous adverse reactions; avoid administering product to patients with history of severe cutaneous adverse reaction to product
Thyroid dysfunction in pediatric patients
- Thyroid dysfunction characterized by hypothyroidism or transient thyroid suppression reported after both single exposure and multiple exposures to iodinated contrast media 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 increased risk of hypothyroidism after ICM exposure
- Pediatric patients with congenital cardiac conditions may be at 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 iodinated contrast media, individualize thyroid function monitoring in pediatric patients 0-3 years of age based on underlying risk factors, especially in term and preterm neonates
- Pediatric patients 0-3 years of age warrant closer monitoring because an underactive thyroid during early life may be harmful to motor, hearing, and cognitive development and may require transient T4 replacement therapy
Pregnancy & Lactation
Pregnancy
Postmarketing data with product use in pregnant women are insufficient to determine if there is risk of drug-associated adverse developmental outcomes; literature reports show that product crosses placenta and is visualized in digestive tract of exposed infants after birth; product crosses placenta and reaches fetal tissues in small amounts; in animal reproduction studies, no adverse developmental effects were observed following intravenous administration of ioversol to pregnant rats and rabbits at doses 0.35 and 0.71 times, respectively, the maximum recommended human dose
Lactation
There is no information about presence of product in human or animal milk, effects of drug on breastfed infant, or effects of drug on milk production; however, iodinated contrast agents are excreted unchanged in human milk in very low amounts with poor absorption from gastrointestinal tract of breastfed infant; the developmental and health benefits of breastfeeding should be considered along with mother’s clinical need for product and any potential adverse effects on breastfed infant from product or from underlying maternal condition; interruption of breastfeeding after exposure to iodinated contrast agents is not necessary because potential exposure of breastfed infant to iodine is small; however, a lactating woman may consider interrupting breastfeeding and pumping and discarding breast milk for 8 hours (approximately 5 elimination half-lives) after product administration in order to minimize drug exposure to breast fed infant
Pregnancy Categories
A: Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.
B: May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk. C: Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done. D: Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk. X: Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist. NA: Information not available.Pharmacology
