Two medicines in one question?
Name two or more medicines and Osler runs an interaction check. A severe interaction is stated at the very top of the answer.
VISIPAQUE is contraindicated for Intrathecal use [see Warnings and Precautions (5.1) ] . Not indicated for intrathecal use. ( 4 )
Warnings and precautions
Hypersensitivity Reactions: Life-threatening or fatal reactions can occur. Always have emergency equipment and trained personnel available. ( 5.2 ) Contrast-Induced Acute Kidney Injury: Acute injury including renal failure can occur. Minimize dose and maintain adequate hydration to minimize risk. ( 5.3 ) Cardiovascular reactions: Hemodynamic disturbances including shock and cardiac arrest may occur during or after administration.
( 5.4 ) Thyroid dysfunction in pediatric patients 0 to 3 Years of Age: Individualize thyroid function monitoring based on risk factors such as prematurity. ( 5.8 )
5.1Risks Associated with Inadvertent Intrathecal Administration
VISIPAQUE is for intravascular use only and is contraindicated for intrathecal use [see Contraindications (4) and Dosage and Administration (2.1) ]. Inadvertent Intrathecal administration can cause death, convulsions/seizures, cerebral hemorrhage, coma, paralysis, arachnoiditis, acute renal failure, cardiac arrest, rhabdomyolysis, hyperthermia, and brain edema.
5.2Hypersensitivity Reactions
VISIPAQUE can cause life-threatening or fatal hypersensitivity reactions including anaphylaxis. Manifestations include respiratory arrest, laryngospasm, bronchospasm, angioedema, and shock. Most severe reactions develop shortly after the start of the injection (within 3 minutes), but reactions can occur up to hours later. There is an increased risk in patients with a history of a previous reaction to contrast agent, and known allergies (i.e., bronchial asthma, drug, or food allergies) or other hypersensitivities.
Premedication with antihistamines or corticosteroids does not prevent serious life-threatening reactions, but may reduce both their incidence and severity. Obtain a history of allergy, hypersensitivity, or hypersensitivity reactions to iodinated contrast agents and always have emergency resuscitation equipment and trained personnel available prior to VISIPAQUE administration. Monitor all patients for hypersensitivity reactions.
5.3Contrast-Induced Acute Kidney Injury
Acute kidney injury, including renal failure, may occur after VISIPAQUE administration. Risk factors include: pre-existing renal impairment, dehydration, diabetes mellitus, congestive heart failure, advanced vascular disease, elderly age, concomitant use of nephrotoxic or diuretic medications, multiple myeloma/paraproteinaceous diseases, repetitive and/or large doses of an iodinated contrast agent. Use the lowest necessary dose of VISIPAQUE in patients with renal impairment.
Adequately hydrate patients prior to and following VISIPAQUE administration. Do not use laxatives, diuretics, or preparatory dehydration prior to VISIPAQUE administration.
or fatal cardiovascular reactions including hypotension, shock, cardiac arrest have occurred with the use of VISIPAQUE. 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. Based upon clinical literature reported deaths from the administration of iodinated contrast agents range from 6.6 per million (0.00066%) to 1 in 10,000 (0.01%).
Use the lowest necessary dose of VISIPAQUE in patients with congestive heart failure and always have emergency resuscitation equipment and trained personnel available. Monitor all patients for severe cardiovascular reactions.
5.5Thromboembolic 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.
5.6Extravasation and Injection Site Reactions Extravasation of
VISIPAQUE 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.
5.7Thyroid 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 VISIPAQUE.
5.8Thyroid 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.
5.9Hypertensive Crisis in Patients with Pheochromocytoma
Hypertensive crisis has occurred after the use of iodinated contrast agents in patient with pheochromocytoma. Monitor patients when administering VISIPAQUE 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.
5.10Sickle 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 VISIPAQUE administration and use VISIPAQUE only if the necessary imaging information cannot be obtained with alternative imaging modalities.
5.11Severe 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 VISIPAQUE to patients with a history of a severe cutaneous adverse reaction to VISIPAQUE.
Interactions
7.1Drug-Drug Interactions Metformin
In patients with renal impairment, metformin can cause lactic acidosis. Iodinated contrast agents appear to increase the risk of metformin-induced lactic acidosis, possibly as a result of worsening renal function. Stop metformin at the time of, or prior to, VISIPAQUE administration in patients with an eGFR between 30 and 60 mL/min/1.73 m 2 ; in patients with a history of hepatic impairment, alcoholism or heart failure; or in patients who will be administered intra-arterial iodinated contrast.
Re-evaluate eGFR 48 hours after the imaging procedure, and reinstitute metformin only after renal function is stable. Radioactive Iodine Administration of iodinated contrast agents may interfere with thyroid uptake of radioactive iodine (I-131 and I-123) and decrease therapeutic and diagnostic efficacy in patients with carcinoma of the thyroid. The decrease in efficacy lasts for 6 to 8 weeks. Beta-adrenergic Blocking Agents The use of beta-adrenergic blocking agents lowers the threshold for and increases the severity of contrast reactions, and reduces the responsiveness of treatment of hypersensitivity reactions with epinephrine.
Because of the risk of hypersensitivity reactions, use caution when administering VISIPAQUE to patients taking beta-blockers. Oral Cholecystographic Contrast Agents Renal toxicity has been reported in patients with liver dysfunction who were given an oral cholecystographic agent followed by intravascular iodinated contrast agents. Postpone the administration of VISIPAQUE in patients who have recently received an oral cholecystographic contrast agent.
7.2Drug-Laboratory Test Interactions Effect on Thyroid Tests
The results of protein bound iodine and radioactive iodine uptake studies, which depend on iodine estimation, will not accurately reflect thyroid function for at least 16 days following administration of iodinated contrast agents. However, thyroid function tests which do not depend on iodine estimations (e.g., T3 resin uptake and total or free thyroxine T4 assays) are not affected. Effect on Urine Tests As reported with other contrast agents, VISIPAQUE may produce a false-positive result for protein in the urine using urine dip tests.
However, the Coomassie blue method has been shown to give accurate results for the measurement of urine protein in the presence of VISIPAQUE. In addition, care should be used in interpreting the results of urine specific gravity measurements in the presence of high levels of VISIPAQUE and other contrast agents in the urine. Refractometry or urine osmolality may be substituted.
Pregnancy and breastfeeding
8.1Pregnancy Risk Summary
There are no data with iodixanol use in pregnant women to inform any drug-associated risks. In animal reproduction studies, no developmental toxicity occurred with intravenous iodixanol administration to rats and rabbits at doses up to 0.24 (rat) or 0.48 (rabbit) times the maximum recommended human intravenous dose ( see Data ). All pregnancies have a background risk of birth defect, loss or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2 to 4% and 15 to 20%, respectively.
Data Animal Data Reproduction studies were performed in rats and rabbits with intravenous administration of iodixanol at doses up to 2 g Iodine/kg, daily, from implantation of the embryo (gestation day 7 in rat; 6 in rabbit) through closure of the hard palate (gestation day 17 in rats; 18 in rabbits). No maternal toxicity occurred, and no adverse effects occurred on fetal survival, embryo-fetal development, or the ability of dams to rear a litter.

6.1Clinical 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. VISIPAQUE is often associated with sensations of discomfort, warmth or pain. In a subgroup of 1259 patients; 30% who received VISIPAQUE or a comparator had application site discomfort, pain, warmth or cold.
VISIPAQUE had a trend toward fewer patient reports of moderate or severe pain or warmth. Pain was reported in 2% of patients receiving VISIPAQUE and 10% of patients receiving a comparator. Heat was reported in 29% of patients receiving VISIPAQUE and 51% of patients receiving a comparator. Table 3 shows the incidence of events reported in blinded, controlled clinical studies of VISIPAQUE in a total of 1244 adult patients.
Adverse events (AEs) are listed by body system and in decreasing order of occurrence greater than 0.5% 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%). A total of 3% of women and 0.8% of men reported chest pain.

6.2Post-marketing Experience
The following additional adverse reactions have been identified during post approval use of VISIPAQUE. 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. Cardiovascular Disorders: Cardiac arrest, palpitations, spasms of coronary arteries, hypertension, and flushing Endocrine Disorders : Hyperthyroidism, hypothyroidism Eye Disorders: Transient visual impairment including cortical blindness, diplopia, and blurred vision Gastrointestinal Disorders: Abdominal pain, pancreatitis, salivary gland enlargement General Disorders and Administration Site Conditions: Chills, pyrexia, pain and discomfort, administration site reactions including extravasation Immune System Disorders: Hypersensitivity reactions, anaphylactic shock including, life-threatening or fatal anaphylaxis Nervous System Disorders: Tremor (transient), coma, disturbance in consciousness, transient contrast-induced encephalopathy caused by extravasation of contrast media (including amnesia, hallucination, paralysis, paresis, transient speech disorder, aphasia, dysarthria) Psychiatric Disorders: Anxiety, agitation Respiratory, Thoracic, and Mediastinal Disorders: Cough, sneezing, throat irritation or tightness, laryngeal edema, pharyngeal edema, bronchospasm Skin and subcutaneous tissue disorders : Reactions range from mild (e.g., rash, erythema, pruritus, urticaria, and skin discoloration) to severe: [e.g., Stevens-Johnson syndrome and toxic epidermal necrolysis (SJS/TEN), acute generalized exanthematous pustulosis (AGEP) and drug reaction with eosinophilia and systemic symptoms (DRESS)]
6.3Pediatric 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 VISIPAQUE 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 VISIPAQUE 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 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 to 2 mL/kg and most patients received a maximu
