WARNING: RISKS ASSOCIATED WITH INTRATHECAL ADMINISTRATION Intrathecal administration, even if inadvertent, may cause death, convulsions, cerebral hemorrhage, coma, paralysis, arachnoiditis, acute renal failure, cardiac arrest, seizures, rhabdomyolysis, hyperthermia, and brain edema. IOMERVU is for intra-arterial or intravenous use only [see Dosage and Administration ( 2.1 ) and Warnings and Precautions ( 5.1 )]. WARNING: RISKS ASSOCIATED WITH INTRATHECAL ADMINISTRATION Intrathecal administration, even if inadvertent, may cause death, convulsions, cerebral hemorrhage, coma, paralysis, arachnoiditis, acute renal failure, cardiac arrest, seizures, rhabdomyolysis, hyperthermia, and brain edema. IOMERVU is for intra-arterial or intravenous use only. (2.1, 5.1)

5 WARNINGS AND PRECAUTIONS Hypersensitivity Reactions: Life-threatening or fatal reactions can occur. Always have emergency resuscitation equipment and trained personnel available. ( 5.2 ) 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 Years 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 IOMERVU is for intra-arterial or intravenous use only and must not be administered intrathecally [see Dosage and Administration ( 2.1 )]. Intrathecal administration, even if inadvertent, can cause death, convulsions, cerebral hemorrhage, coma, paralysis, arachnoiditis, acute renal failure, cardiac arrest, seizures, rhabdomyolysis, hyperthermia, and brain edema. 5.2 Hypersensitivity Reactions IOMERVU can cause life-threatening or fatal hypersensitivity reactions including anaphylaxis. Manifestations include respiratory arrest, laryngospasm, bronchospasm, angioedema, and shock [see Adverse Reactions ( 6.2 )]. Most severe reactions develop shortly after the start of injection (e.g., within 1 to 3 minutes), but delayed reactions can occur. There is an increased risk in patients with a history of a previous reaction to contrast agents, and known allergic disorders (i.e., bronchial asthma, drug, or food allergies) or other hypersensitivities. Premedication with antihistamines or corticosteroids to minimize possible allergic reactions does not prevent serious life-threatening reactions, but may reduce their incidence and severity. Obtain a history of allergy, hypersensitivity, and hypersensitivity reactions to iodinated contrast agents. Always have emergency resuscitation equipment and trained personnel available before use of IOMERVU. Monitor all patients for hypersensitivity reactions. 5.3 Acute Kidney Injury Acute kidney injury, including renal failure, may occur after IOMERVU administration. Risk factors include pre-existing renal impairment, dehydration, diabetes mellitus, heart failure, advanced vascular disease, advanced age, concomitant use of nephrotoxic or diuretic medications, multiple myeloma or other paraproteinemia, and repetitive or large doses of IOMERVU. Use the lowest necessary dose of IOMERVU in patients with renal impairment. Adequately hydrate patients prior to and following IOMERVU administration. Do not use laxatives, diuretics, or preparatory dehydration prior to IOMERVU administration. 5.4 Cardiovascular Adverse Reactions IOMERVU increases the circulatory osmotic load and may induce acute or delayed hemodynamic disturbances in patients with heart failure, severely impaired renal function, combined renal and hepatic disease, or combined renal and cardiac disease, particularly when repetitive or large doses are administered. Life-threatening or fatal cardiovascular reactions including hypotension, shock, and cardiac arrest have occurred with the use of IOMERVU. 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 IOMERVU in patients with heart failure and always have emergency resuscitation equipment and trained personnel available. Monitor all patients for severe cardiovascular reactions. 5.5 Thromboembolic Events Serious, in some cases fatal, thromboembolic events including myocardial infarction and stroke can occur during angiographic procedures with iodinated contrast agents including IOMERVU. During these procedures, increased thrombosis and activation of the complement system can occur. Risk factors for developing thromboembolic events include length of procedure, catheter and syringe material, underlying disease state, and concomitant medications. To reduce risk of thromboembolic events, use meticulous angiographic techniques and minimize the length of the procedure. Avoid blood remaining in contact with syringes containing IOMERVU, which increases the risk of clotting. Avoid angiocardiography in patients with homocystinuria because of the risk of inducing thrombosis and embolism. 5.6 Extravasation and Injection Site Reactions Extravasation can occur with IOMERVU administration, particularly in patients with severe arterial or venous disease. Inflammation, blistering, skin necrosis, and compartment syndrome have been reported following extravasation. In addition, injection site reactions such as pain and swelling at the injection site can also occur [see Adverse Reactions ( 6.1 , 6.2 )] . 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 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 IOMERVU. 5.8 Thyroid Dysfunction in Pediatric Patients 0 Years 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 agents in pediatric patients 0 years 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 iodinated contrast agent 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 IOMERVU, 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 contrast agents in patients with pheochromocytoma. Closely monitor patients when administering IOMERVU if pheochromocytoma or catecholamine-secreting paragangliomas are suspected. Inject the minimum amount of IOMERVU necessary, assess blood pressure throughout the procedure, and have measures for treatment of a hypertensive crisis readily available. 5.10 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 IOMERVU administration and use IOMERVU only if the necessary imaging information cannot be obtained with alternative imaging modalities. 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 IOMERVU to patients with a history of a severe cutaneous adverse reaction to IOMERVU. 5.12 Interference with Laboratory Tests IOMERVU can interfere with protein-bound iodine tests [see Drug Interactions ( 7.2 )].

Adverse Reactions in Adult Patients The safety of IOMERVU was evaluated in 4,621 adult patients who received 1,500 mg to 86,000 mg iodine doses of IOMERVU intra-arterially or intravenously in clinical trials. The average age was 60 years (range 18 years to 99 years), and 34% were female. The racial and ethnic distribution was 83% White, 10% Asian, 1% Black, 1% Hispanic, and 5% patients of other or unspecified groups. Table 5 provides a summary of the adverse reactions reported in ≥0.5% of adult patients.
