DOSAGE AND ADMINISTRATION Adjust the volume and concentration of OPTIRAY. Modify the dose accounting for factors such as age, body weight, vessel size, blood flow rate within the vessel. Please see details in full Prescribing Information. ( 2 ) 2.1 Important Administration Instructions OPTIRAY is for intravascular use only [see Boxed Warning, Contraindications ( 4 ), Warnings and Precautions ( 5.1 )] . Use sterile technique for all handling and administration of OPTIRAY. Inspect glass and plastic containers prior to use for breakage or other damage and do not use damaged containers. Warm OPTIRAY and administer at body or room temperature. Inspect OPTIRAY for particulate matter or discoloration before administration. Do not administer if OPTIRAY contains particulate matter or is discolored. Do not mix OPTIRAY with other drugs, solutions or total parenteral nutrition mixtures. Use the lowest dose necessary to obtain adequate visualization. Adjust the volume and concentration of OPTIRAY. Modify the dose accounting for factors such as age, body weight, vessel size, blood flow rate within the vessel, anticipated pathology, degree and extent of opacification required, structure(s) or area to be examined, disease processes affecting the patient, and equipment and technique to be employed. Avoid extravasation when injecting OPTIRAY; especially in patients with severe arterial or venous disease [see Warnings and Precautions ( 5.6 )]. Hydrate patients before and after OPTIRAY administration [see Warnings and Precautions ( 5.3 )]. Discard unused portion of OPTIRAY from single-dose container after use. 2.2 Radio Frequency Identification (RFID)-Tagged Syringe Directions for Use The RFID-tagged syringe must be used with an Optivantage Injector with RFID technology [see How Supplied/Storage and Handling ( 16.2 )] . The RFID tag allows for the exchange of product information such as lot number, expiration, concentration, and identification of the syringe as being “unused” prior to use and “used” after product administration. Do not operate any part of the Optivantage Injector System and RFID-tagged syringes within 6 inches (15 cm) of a pacemaker and/or defibrillator. If the RFID tag is damaged or otherwise non-functional, the OPTIRAY syringe with the non-functional RFID tag may still be used; however, no data will be transferred to the injector. 2.3 Intra-arterial Procedures in Adults Cerebral Arteriography Use OPTIRAY 300 or OPTIRAY 320.

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 Adverse 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 ) 5.1 Risks Associated with Inadvertent Intrathecal Administration OPTIRAY is indicated for intravascular use only [see Dosage and Administration ( 2.1 )] . Inadvertent intrathecal administration can cause death, convulsions, cerebral hemorrhage, coma, paralysis, arachnoiditis, acute renal failure, cardiac arrest, seizures, rhabdomyolysis, hyperthermia, and brain edema. 5.2 Hypersensitivity Reactions OPTIRAY can cause life-threatening or fatal hypersensitivity reactions including anaphylaxis and anaphylactic shock. Manifestations include respiratory arrest, laryngospasm, bronchospasm, angioedema, and shock. Most severe reactions develop shortly after the start of the injection (e.g. within 1 to 3 minutes), but delayed reactions may occur. 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), and other hypersensitivities. Premedication with antihistamines or corticosteroids to avoid or minimize possible allergic reactions does not prevent serious life-threatening reactions, but may reduce both their incidence and severity. 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. 5.3 Contrast Induced Acute Kidney Injury Acute kidney injury, including renal failure, may occur after OPTIRAY 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 OPTIRAY in patients with renal impairment. Adequately hydrate patients prior to and following OPTIRAY administration. Do not use laxatives, diuretics, or preparatory dehydration prior to OPTIRAY administration. 5.4 Cardiovascular Adverse Reactions OPTIRAY increases the circulatory osmotic load and may induce acute or delayed hemodynamic disturbances in patients with congestive heart failure, severely impaired renal function, combined renal and hepatic disease, combined renal and cardiac disease, particularly when repetitive or large doses are administered. Life-threatening or fatal cardiovascular reactions have occurred with the use of OPTIRAY, including cardiac arrest, hypotensive collapse, and shock. Most deaths occur within 10 minutes of injection; with cardiovascular disease as the main underlying factor. Cardiac decompensation, serious arrhythmias, and myocardial ischemia or infarction can occur during coronary arteriography and ventriculography. Based upon literature reports, deaths from the administration of iodinated contrast agents range from 6.6 per 1 million (0.00066 percent) to 1 in 10,000 patients (0.01 percent). Use the lowest necessary dose of OPTIRAY in patients with congestive heart failure and always have emergency resuscitation equipment and trained personnel available. Monitor all patients for severe cardiovascular reactions. 5.5 Thromboembolic Events Angiocardiography Serious, fatal, thromboembolic events causing myocardial infarction and stroke can occur during angiographic procedures with OPTIRAY. 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 technique. Avoid blood remaining in contact with syringes containing OPTIRAY, which increases the risk of clotting. Avoid angiocardiography in patients with homocystinuria because of the risk of inducing thrombosis and embolism [see Clinical Pharmacology ( 12.2 )] . 5.6 Extravasation and Injection Site Reactions Extravasation can occur with OPTIRAY administration, particularly in patients with severe arterial or venous disease and can be associated with pain, hemorrhage and necrosis. Ensure intravascular placement of catheters prior to injection. Monitor patients for extravasation and advise patients to seek medical care for progression of symptoms. 5.7 Thyroid Storm in Patients with Hyperthyroidism OPTIRAY is contraindicated in patients with symptomatic hyperthyroidism [see Contraindications ( 4 )] . Thyroid storm has occurred following the intravascular use of iodinated radiopaque agents in patients with hyperthyroidism or with an autonomously functioning thyroid nodule. Evaluate the risk in such patients before use of OPTIRAY. 5.8 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. 5.9 Hypertensive Crisis in Patients with Pheochromocytoma Hypertensive crisis has occurred after the use of iodinated radiopaque contrast agents in patient with pheochromocytoma. Closely monitor patients when administering OPTIRAY if pheochromocytoma or catecholamine-secreting paraganglioma is suspected. Inject the minimum amount of OPTIRAY necessary and have measures for treatment of hypertensive crisis readily available. 5.10 Sickle Cell Crisis in Patients with Sickle Cell Disease Iodinated contrast agents may promote sickling in individuals who are homozygous for sickle cell disease. Hydrate patients prior to and following OPTIRAY administration, use OPTIRAY only if the necessary imaging information cannot be obtained with alternative imaging modalities, and inject the minimum amount necessary. 5.11 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 a contrast agent; prophylactic medications may not prevent or mitigate severe cutaneous adverse reactions. Avoid administering OPTIRAY to patients with a history of a severe cutaneous adverse reaction to OPTIRAY.

CONTRAINDICATIONS Symptomatic hyperthyroidism. Symptomatic Hyperthyroidism ( 4 )

DRUG INTERACTIONS 7.1 Drug-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, OPTIRAY 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 agents. Re-evaluate eGFR 48 hours after the imaging procedure, and reinstitute only after renal function is stable. Radioactive Iodine Administration of iodinated contrast agents may interfere with thyroid uptake of radioactive iodine (I 131) and decrease therapeutic efficacy in patients with carcinoma of the thyroid. The decrease in efficacy lasts for 6-8 weeks. Oral Cholecystographic Contrast Agents Renal toxicity has been reported in patients with liver impairment who were given oral cholecystographic agents followed by intravascular contrast agents. Administration of OPTIRAY should be postponed in patients who have recently received a cholecystographic contrast agent. 7.2 Drug/Laboratory Test Interactions Protein-Bound Iodine, Radioactive Iodine Determinations The results of protein bound iodine and radioactive iodine uptake studies, which depend on iodine estimation, will not accurately reflect thyroid function for up to 16 days following administration of iodinated contrast agent. However, thyroid function tests that do not depend on iodine estimations, e.g., T3 resin uptake and total or free thyroxine (T4) assays are not affected.

Adverse reactions reported were similar in quality and frequency to the adverse events reported by adults. 6.2 Postmarketing Experience The following additional adverse drug reactions have been reported during post-approval use of OPTIRAY. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate frequency or establish a causal relationship to drug exposure. Cardiac disorders: coronary artery spasm, cyanosis, arrhythmia (ventricular fibrillation, tachycardia, extrasystole), ECG abnormal. Endocrine disorders: hyperthyroidism, hypothyroidism. Eye disorders: temporary blindness, conjunctivitis (including eye irritation, ocular hyperemia, watery eyes). Gastrointestinal disorders: tongue edema, salivary hypersecretion. General disorders and administration site conditions: injection site reactions including pain, hemorrhage, and necrosis especially after extravasation [see Warnings and Precautions ( 5.6 )] , face edema, feeling hot.

Respiratory disorders: Respiratory arrest, asthma, bronchospasm, laryngeal spasm and obstruction, throat irritation, dysphonia. 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). Vascular Disorders: phlebitis, thrombosis.

Mechanism of Action Intravascular injection of ioversol opacifies those vessels in the path of the flow of the contrast medium, permitting radiographic visualization of the internal structures until significant hemodilution occurs. Ioversol may be visualized in the renal parenchyma within 30 to 60 seconds following rapid intravenous injection. Opacification of the calyces and pelves in patients with normal renal function becomes apparent within 1 to 3 minutes, with optimum contrast occurring within 5 to 15 minutes. OPTIRAY enhances computed tomographic imaging through augmentation of radiographic efficiency. The degree of density enhancement is directly related to the iodine content in an administered dose; peak iodine blood levels occur immediately following rapid intravenous injection. Blood levels fall rapidly within 5 to 10 minutes and the vascular compartment half-life is approximately 20 minutes. This can be accounted for by the dilution in the vascular and extravascular fluid compartments which causes an initial sharp fall in plasma concentration. Equilibration with the extracellular compartments is reached in about 10 minutes; thereafter, the fall becomes exponential.
