WARNINGS AND PRECAUTIONS:

Risks Associated with Intrathecal Administration of OMNIPAQUE injection 140 mg iodine/mL and 350mg iodine/ml:  Use only the iodine concentrations and presentations recommended for intrathecal procedures. See Boxed Warning

Risks Associated with Parenteral Administration of OMNIPAQUE Oral Solution:  Use for oral use only. Adverse reactions such as hemolysis may occur if OMNIPAQUE is administered intravenously or intraarterially due to low osmolality.

Hypersensitivity Reactions: OMNIPAQUE can cause life-threating or fatal hypersensitivity reactions including anaphylaxis. Most severe reactions develop shortly after the start of the injection (within 1 to 3 minutes), but delayed reactions can also occur. There is an increased risk in patients with a history of a previous reaction to contrast agent and known allergic disorders or other hypersensitivities.  Premedication with antihistamines or corticosteroids does not prevent serious life-threatening reactions but may reduce both incidence and severity.

Acute Kidney Injury:  Acute kidney injury, including renal failure, may occur after parenteral administration of OMNIPAQUE. 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 lowest dose in patients with renal impairment.  Adequately hydrate patients prior to administration and do not use laxatives, diuretics, or preparatory dehydration prior to OMNIPAQUE administration.

Cardiovascular Adverse Reactions: Life-threatening or fatal cardiovascular reactions including hypotension, shock, cardiac arrest have occurred with the parenteral administration of OMNIPAQUE. Most deaths occur during the injection or 5-10 minutes later, with cardiovascular disease as the main aggravating factor. Use the lowest dose necessary in patient with congestive heart failure and have resuscitation equipment and trained personnel available.

Thromboembolic Events: Serious, rarely fatal, thromboembolic events causing myocardial infarction and stroke can occur during angiocardiography procedures with iodinated contrast agents. Risk factors for thromboembolic events include: length of procedure, catheter and syringe material, underlying disease state, and concomitant medications. Use meticulous angiographic techniques and minimize length of procedures to minimize events. Avoid blood remaining in contact with syringes containing OMNIPAQUE and avoid angiocardiography in patients with homocystinuria.

Extravasation and Injection Site Reactions: Extravasation of OMNIPAQUE during intravenous or intra-arterial injection may cause tissue necrosis and/or compartment syndrome, particularly in patients with severe arterial or venous disease. Ensure correct placement and monitor patients for extravasation.

Thyroid Storm in Patients with Hyperthyroidism: Thyroid storm has occurred after the intravenous or intra-arterial use of iodinated contrast agents in patients with hyperthyroidism, or with an autonomously functioning thyroid nodule. Evaluate the risk in these patients before use of OMNIPAQUE.

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.

Hypertensive Crisis in Patients with Pheochromocytoma: Hypertensive crisis has occurred after the use of iodinated contrast agents in patients with pheochromocytoma.  Monitor patients when administering OMNIPAQUE intravenously or intra-arterially. Use the minimum amount of contrast necessary and monitor blood pressure throughout the procedure.

Sickle Cell Crisis in Patients with Sickle Cell Disease: Iodinated contrast agents when administered intravenously or intra-arterially may promote sickling in individuals who have sickle cell disease. Hydrate patient prior to and following OMNIPAQUE administration and use OMNIPAQUE only if the necessary imaging cannot be obtained with alternative imaging modalities.

Severe Cutaneous Adverse Reactions: Severe cutaneous adverse reactions may develop from 1 hour to several weeks after intravenous or intra-arterial contrast agent administration. These reactions include Stevens-Johnson syndrome and toxic epidermal necrolysis, acute generalized exanthematous pustulosis and drug reaction with eosinophilia and systemic symptoms. Reaction severity may increase and time to onset my decrease with repeat administration of contrast agents. Prophylactic medications may not prevent or mitigate severe cutaneous adverse reactions. Avoid administering to patients with a history of severe cutaneous reactions.

Interference with Laboratory Test: OMNIPAQUE can interfere with protein-bound iodine test.

Increased Risk of Seizures with Intrathecal Procedures: Focal and generalized motor seizures have been reported after intrathecal use of iodinated contrast agents. Use of medications that may lower the seizure threshold should be carefully evaluated. Consider discontinuing these agents at least 48 hours before and at least 24 hours following intrathecal administration of OMNIPAQUE.

Most Common Adverse Reactions

Intrathecal Administration: In clinical trials ≥1% of 1,531 adult patients included: headaches, pain (including backache, neckache, stiffness, and neuralgia), nausea, vomiting and dizziness. In clinical trials ≥1% of 152 pediatric patients included headache, vomiting and backache.

Intra-arterial or Intravenous Administration: In clinical trials ≥1% of 1,485 adult patients included arrhythmias (including PVCs and PACs), pain, vision abnormalities (including blurred vision and photomas), taste perversion and nausea. In clinical trials ≥1% of 391 pediatric patients included vomiting and nausea.

Oral or Rectal Administration for Examination of the Gastrointestinal Tract: In clinical trials ≥1% of 54 adult patients included diarrhea, nausea, vomiting, abdominal pain, flatulence and headache. In clinical trials of 58 pediatric patients included diarrhea, vomiting, nausea, abdominal pain, fever, urticaria and hypotension.

Intraarticular Administration: In clinical trials ≥1% of 285 adult patients included administration site pain, swelling and heat.

Body Cavity Use: No new adverse reactions were associated with the use of OMNIPAQUE in 51 pediatric patients.

Drug-Drug Interactions:

In patients with renal impairment, metformin can cause lactic acidosis.

OMNIPAQUE may interfere with thyroid uptake of radioactive iodine and decrease therapeutic and diagnostic efficacy. Avoid thyroid therapy or testing for up to 6 weeks post OMNIPAQUE.

Pregnancy and Lactation:

There are no data with iohexol use in pregnant women. Published literature report intravenously iohexol crosses the placenta and is visualized in the digestive tract of exposed infants after birth.

Published literature reports that breast feeding after intravenous iohexol administration to the mother would result in the infant receiving an oral dose of approximately 0.7% of the maternal intravenous dose. Lactating women may consider pumping and discarding breast milk for 10 hours after OMNIPAQUE administration to minimize drug exposure to the breastfed infant.

Prior to Omnipaque administration, please read the full Prescribing Information, including Boxed Warning, for Omnipaque.

IMPORTANT SAFETY INFORMATION FOR VISIPAQUE (iodixanol) INJECTION

CONTRAINDICATION: Visipaque injection is contraindicated for intrathecal use.

WARNINGS AND PRECAUTIONS:
• Hypersensitivity Reactions: Life-threatening or fatal reactions can occur. Most severe reactions develop shortly after the start of the injection, but reactions can occur up to hours later. Always have emergency equipment and trained personnel available.
• Contrast Induced Acute Kidney Injury: Acute injury including renal failure can occur. Minimize dose and maintain adequate hydration to minimize risk.
• Cardiovascular Reactions: Life-threatening or fatal cardiovascular reactions, including hypotension, shock, and 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. Use the lowest necessary dose of Visipaque in patients with congestive heart failure.
• Thromboembolic Events: Serious, rarely fatal, thromboembolic events causing myocardial infarction and stroke can occur during angiocardiography procedures with both ionic and nonionic contrast agents.
• 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.
• 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.
• 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 patients 0 to 3 years of age.
• Hypertensive Crisis in Patients with Pheochromocytoma: Hypertensive crisis has occurred after the use of iodinated contrast agents in patients with pheochromocytoma. 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.
• 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.
• Severe Cutaneous Adverse Reactions (SCAR): SCAR may develop from one 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). Avoid administering Visipaque to patients with a history of a SCAR to Visipaque.

USE IN SPECIFIC POPULATIONS:
• Pediatric Use: Pediatric patients at high risk of adverse reactions during and after administration of contrast agents include those with asthma, hypersensitivity to other medication and/or allergens, cyanotic and acyanotic heart disease, chronic heart failure, or a serum creatinine >1.5 mg/dL. Patients with immature renal function or dehydration may be at increased risk due to prolonged elimination of iodinated contrast agents.
• Geriatric Use: While no overall differences in safety or effectiveness were observed in patients >65 years, greater sensitivity regarding some older individuals cannot be ruled out.

ADVERSE REACTIONS:
• Serious, life-threatening, and fatal reactions, mostly of cardiovascular origin, have been associated with the administration of iodine-containing contrast agents, including Visipaque Injection.
• Most common adverse reactions (incidence greater than 0.5%) in adult patients after Visipaque injection: Discomfort, warmth, pain; Cardiovascular: angina. Gastrointestinal: diarrhea, nausea, vomiting. Nervous System: agitation, anxiety, insomnia, nervousness, dizziness, headache, migraine, unusual skin sensations, sensory disturbance, fainting, sensation of spinning. Skin: itchy rash, severe itching, hives. Special Senses: Smell, taste, and vision alteration. Pediatric patients experienced similar adverse reactions.

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, Visipaque administration in patients with an eGFR between 30 and 60 mL/min/1.73 m2; 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 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 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 agent.

INDICATIONS

Clariscan™ (gadoterate meglumine) is a gadolinium-based contrast agent indicated for intravenous use with magnetic resonance imaging (MRI) in brain (intracranial), spine and associated tissues in adult and pediatric patients (including term neonates) to detect and visualize areas with disruption of the blood brain barrier (BBB) and/or abnormal vascularity.

CONTRAINDICATIONS

History of clinically important hypersensitivity reactions to Clariscan.

WARNINGS AND PRECAUTIONS 

Risk Associated with Intrathecal Use: Intrathecal administration of GBCAs can cause serious adverse reactions including death, coma, encephalopathy, and seizures. The safety and effectiveness of Clariscan have not been established with intrathecal use.

Nephrogenic Systemic Fibrosis: GBCAs increase the risk for NSF among patients with impaired elimination of the drugs. Avoid use of Clariscan among these patients unless the diagnostic information is essential and not available with non-contrast MRI or other modalities.

Hypersensitivity Reactions: Anaphylactic and anaphylactoid reactions have been reported with gadoterate meglumine, involving cardiovascular, respiratory, and/or cutaneous manifestations. Some patients experienced circulatory collapse and died.

Before Clariscan administration, assess all patients for any history of a reaction to contrast media, bronchial asthma and/or allergic disorders. These patients may have an increased risk for a hypersensitivity reaction to Clariscan. Administer Clariscan only in situations where trained personnel and therapies are promptly available for the treatment of hypersensitivity reactions, including personnel trained in resuscitation. Observe for signs and symptoms of hypersensitivity reactions during and following administration.

Gadolinium Retention: Gadolinium is retained for months or years in several organs. The highest concentrations have been identified in the bone, followed by other organs (e.g. brain, skin, kidney, liver and spleen). While clinical consequences of gadolinium retention have not been established in patients with normal renal function, certain patients might be at higher risk. These include patients requiring multiple lifetime doses, pregnant and pediatric patients, and patients with inflammatory conditions. Minimize repetitive GBCA imaging studies, particularly closely spaced studies when possible.

Acute Kidney Injury: In patients with chronically reduced renal function, acute kidney injury requiring dialysis has occurred with the use of GBCAs. The risk of acute kidney injury may increase with increasing dose of the contrast agent; administer the lowest dose necessary for adequate imaging.

Extravasation and Injection Site Reactions: Ensure catheter and venous patency before the injection of Clariscan. Extravasation into tissues during Clariscan administration may result in tissue irritation.

ADVERSE REACTIONS

Most Common Adverse Reactions: In clinical trials, the most frequent adverse reactions that occurred in > 0.2% of patients who received Clariscan included: nausea, headache, injection site pain, injection site coldness and rash.

USE IN SPECIFIC POPULATIONS

Pregnancy and Lactation: GBCAs cross the human placenta and result in fetal exposure and gadolinium retention. Use only if imaging is essential during pregnancy and cannot be delayed.   There are no data on the presence of gadoterate in human milk, the effects on the breastfed infant, or the effects on milk production. However, published lactation data on other GBCAs indicate that 0.01 to 0.04% of the maternal gadolinium dose is present in breast milk.

Prior to Clariscan administration, please read the full Prescribing Information for

additional Important Safety Information.

INDICATIONS:

OPTISON is an ultrasound contrast agent indicated for use in adult and pediatric patients with suboptimal echocardiogram to opacify to the left ventricle to improve the delineation of the left ventricle endocardial borders.

CONTRAINDICATIONS:
OPTISON is contraindicated in patients with known or suspected hypersensitivity to perflutren or albumin.

 WARNINGS AND PRECAUTIONS:

• Serious cardiopulmonary reactions including fatalities have occurred uncommonly during or shortly following perflutren-containing microsphere administration, typically within 30 minutes of administration. The risk for these reactions may be increased among patients with unstable cardiopulmonary conditions (acute myocardial infarction, acute coronary artery syndromes, worsening or unstable congestive heart failure, or serious ventricular arrhythmias).
• Serious anaphylactic reactions have been observed during or shortly following perflutren-containing microsphere administration, including shock, hypersensitivity, bronchospasm, throat tightness, angioedema, edema (pharyngeal, palatal, mouth, peripheral, localized), swelling (face, eye, lip, tongue, upper airway), facial hypoesthesia, rash, urticaria, pruritus, flushing, and erythema have occurred in patients with no prior exposure to perflutren-containing microsphere products.
• When administering OPTISON to patients with a cardiac shunt, microspheres can bypass filtering of the lungs and enter the arterial circulation. Assess patients with shunts for embolic phenomena following OPTISON administration. OPTISON is only for intravenous administration; do not administer OPTISON by intra-arterial injection.
• High ultrasound mechanical index values may cause microsphere rupture and lead to ventricular arrhythmias. Additionally, end-systolic triggering with high mechanical indices has been reported to cause ventricular arrhythmias. OPTISON is not recommended for use at mechanical indices greater than 0.8.

Adverse Reactions

Common adverse reactions (incidence > 0.5%) were: headache, nausea and/or vomiting, warm sensation or flushing, dizziness, dysgeusia, chills or fever, flu-like symptoms, malaise/weakness/fatigue, chest pain, dyspnea, injection site discomfort, and erythema. Cardiac arrests and other serious but nonfatal adverse reactions were uncommonly reported in post-approval use. Reports also identified neurologic reactions (loss of consciousness or convulsions) as well as anaphylactoid reactions.  Overall, the safety profile observed in pediatric patients from the clinical study was consistent with the safety profile in adult patients.

Use in Specific Populations

Pregnancy and Lactation

There are no data with OPTISON use in pregnant woman to inform any drug-associated risks. 

There are no data on the presence of perflutren protein-type A microspheres in human milk, the effects on the breastfed infant or the effects on milk production.

Pediatric Use

Safety and efficacy of OPTISON in pediatric patient is supported by evidence from adequate and well-controlled studies in adults and additional efficacy and safety data from a clinical study in 37 pediatric patients aged 9-17 years.

Geriatric Use

No overall differences in safety or effectiveness were observed in patients 65 years and over but a greater sensitivity to OPTISON in older individuals cannot be ruled out.

Please see the full Prescribing Information, including Boxed Warning for additional important safety information.

Indications
CNS (Central Nervous System): OMNISCAN is a gadolinium-based contrast agent indicated for intravenous use in MRI to visualize lesions with abnormal vascularity (or those thought to cause abnormalities in the blood-brain barrier) in the brain (intracranial lesions), spine, and associated tissues.

Body (Intrathoracic [noncardiac], Intra-abdominal, Pelvic and Retroperitoneal Regions): OMNISCAN is a gadolinium-based contrast agent indicated for intravenous use in MRI to facilitate the visualization of lesions with abnormal vascularity within the thoracic (noncardiac), abdominal, pelvic cavities, and the retroperitoneal space.

Important Safety Information
OMNISCAN is contraindicated in patients with chronic, severe kidney disease (glomerular filtration rate, GFR < 30 mL/min/1.73m²) or acute kidney injury and/or prior hypersensitivity to OMNISCAN.

Risk Associated with Intrathecal Use: Intrathecal administration of GBCAs can cause serious adverse reactions including death, coma, encephalopathy, and seizures. The safety and effectiveness of OMNISCAN have not been established with intrathecal use. OMNISCAN is not approved for intrathecal use.

Nephrogenic Systemic Fibrosis: GBCAs increase the risk for nephrogenic systemic fibrosis (NSF) among patients with impaired elimination of the drugs. Avoid use of OMNISCAN among these patients unless the diagnostic information is essential and not available with non-contrast enhanced MRI or other modalities. The GBCA-associated NSF risk appears highest for patients with chronic, severe kidney disease as well as patients with acute kidney injury. Do not administer OMNISCAN to these patients. Screen patients for acute kidney injury and other conditions that may reduce renal function. Do not exceed the recommended dose.

Hypersensitivity Reactions: Anaphylactoid and anaphylactic reactions, with cardiovascular, respiratory and/or cutaneous manifestations, resulting in death have occurred. Trained personnel and resuscitation equipment should be present prior to administration. Stop OMNISCAN if hypersensitivity reactions occur. Closely monitor patients with a history of drug reactions, asthma, allergies and hypersensitivity disorders.

Gadolinium Retention: Gadolinium is retained for months or years in several organs; especially bone and other organs. Consequences of gadolinium retention in the brain have not been established. Pathologic and clinical consequences of GBCA administration and retention in skin and other organs have been established in patients with impaired renal function.

Acute Renal Failure: In patients with renal insufficiency, acute renal failure requiring dialysis or worsening renal function have occurred, mostly within 48 hours of OMNISCAN Injection. The risk of renal failure may increase with increasing dose of gadolinium contrast. Use the lowest necessary.

Impaired Visualization of Lesions Detectable with non-contrast MRI: Paramagnetic contrast agents such as OMNISCAN might impair the visualization of lesions which are seen on the non-contrast MRI. Exercise caution when OMNISCAN MRI scans are interpreted in the absence of a companion non-contrast MRI.

Laboratory Test Findings: Asymptomatic, transitory changes in serum iron have been observed. The clinical significance is unknown. In patients with decreased renal function, the interference with calcium measurements is expected to last during the prolonged elimination of OMNISCAN. After patients receive OMNISCAN, careful attention should be used in selecting the type of method used to measure calcium.

Adverse Reactions: The most frequent adverse reactions were nausea, headache, and dizziness that occurred in 3% or less of the patients. Postmarketing experience reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure: acute pancreatitis with onset within 48 hours after GCBA administration. Please see full prescribing information for a complete list of adverse reactions including postmarketing events.

Pregnancy: GBCAs cross the human placenta and result in fetal exposure and gadolinium retention. The human data on the association between GBCAs and adverse fetal outcomes are limited and inconclusive.

Prior to Omniscan administration, please read the full Prescribing Information for additional Important Safety Information.
