5 WARNINGS AND PRECAUTIONS Pulmonary and cerebral embolism: avoid use in patients with severely impaired lung function, cardiorespiratory failure or right-sided cardiac overload ( 5.1 ) Hypersensitivity reactions: avoid use in patients with a history of sensitivity to other iodinated contrast agents, bronchial asthma or allergic disorders because of an increased risk of a hypersensitivity reaction to Lipiodol ( 5.2 ) Exacerbation of chronic liver disease ( 5.3 ) Thyroid dysfunction ( 5.4 ) 5.1 Pulmonary and Cerebral Embolism Pulmonary embolism may occur immediately or after a few hours to days from inadvertent systemic vascular injection or intravasation of Lipiodol and cause decreased pulmonary diffusing capacity and pulmonary blood flow, pulmonary infarction, acute respiratory distress syndrome and fatalities. Embolization of Lipiodol to brain and other major organs may occur. Avoid use of Lipiodol in patients with severely impaired lung function, cardiorespiratory failure, or right–sided cardiac overload. Perform radiological monitoring during the Lipiodol injection. Do not exceed the recommended maximum dose and rate of injection of Lipiodol. During lymphography to minimize the risk of pulmonary embolism obtain radiographic confirmation of intralymphatic (rather than venous) injection, and terminate the procedure when Lipiodol becomes visible in the thoracic duct or lymphatic obstruction is observed. 5.2 Hypersensitivity Reactions Anaphylactoid and anaphylactic reactions with cardiovascular, respiratory or cutaneous manifestations, ranging from mild to severe, including death, have uncommonly occurred following Lipiodol administration. Avoid use in patients with a history of sensitivity to other iodinated contrast agents, bronchial asthma or allergic disorders because of an increased risk of a hypersensitivity reaction to Lipiodol. Administer Lipiodol only in situations where trained personnel and therapies are promptly available for the treatment of hypersensitivity reactions, including personnel trained in resuscitation; ensure continuous medical monitoring and maintain an intravenous access line. Most hypersensitivity reactions to Lipiodol occur within half an hour after administration. Delayed reactions can occur up to several days after administration. Observe patients for signs and symptoms of hypersensitivity reactions during and for at least 30 minutes following Lipiodol administration. 5.3 Exacerbation of Chronic Liver Disease Lipiodol hepatic intra-arterial administration can exacerbate the following conditions: portal hypertension and cause variceal bleeds due to obstruction of the intrahepatic portal channels by opening a pre sinusoidal anastomosis; hepatic ischemia and cause liver enzyme elevations, fever and abdominal pain; hepatic failure and cause ascites and encephalopathy. Hepatic vein thrombosis, irreversible liver insufficiency and fatalities have been reported. Procedural risks include vascular complications and infections. 5.4 Thyroid Dysfunction Iodinated contrast media can affect thyroid function because of the iodide content and can cause hyperthyroidism or hypothyroidism. Ethiodized oil may remain in the body for several months, depending on dose administered and route of administration. Keep the dose of Lipiodol as low as possible and consider monitoring thyroid function closely for several months after administration of Lipiodol.
6 ADVERSE REACTIONS Adverse reactions caused by Lipiodol include hypersensitivity reactions, pulmonary embolism, pulmonary dysfunction, exacerbation of liver disease, procedural complications, abdominal pain, fever, nausea, vomiting, and thyroid dysfunction. To report SUSPECTED ADVERSE REACTIONS, contact GUERBET LLC at 1-877-729-6679 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch 6.2 Postmarketing Experience The following adverse reactions (Table 1) have been identified during post approval use of Lipiodol. 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 drug exposure. The following adverse reactions are described in more detail in other sections of the prescribing information: Pulmonary and cerebral embolism [see Warnings and Precautions ( 5.1 ) ] Hypersensitivity reactions [see Warnings and Precautions ( 5.2 ) ] Exacerbation of chronic liver disease [see Warnings and Precautions ( 5.3 ) ] Thyroid dysfunction [see Warnings and Precautions ( 5.4 ) ]. Thyroid dysfunction in the mother and the infant of a subsequent pregnancy [See Use in Specific Populations ( 8.1 )] Table 1: Adverse Reactions in the Postmarketing Experience System Organ Class Adverse Reaction Eye disorders retinal vein thrombosis General disorders and administration site conditions fever, pain, granuloma Immune system disorders hypersensitivity, anaphylactic reaction, anaphylactoid reaction, cardiovascular reactions Nervous system disorders cerebral embolism Respiratory, thoracic and mediastinal disorders pulmonary embolism, dyspnea, cough, acute respiratory distress syndrome Urinary system disorders renal insufficiency Hysterosalpingography Abdominal pain, foreign body reactions, exacerbation of pelvic inflammatory disease, salpingitis or pelvic peritonitis have been reported after the examination in case of latent infection. Lymphography Lymphangitis, thrombophlebitis, edema or exacerbation of preexisting lymphedema, dyspnea and cough, iodism (headache, soreness of mouth and pharynx, coryza and skin rash), allergic dermatitis, lipogranuloma, delayed healing at the site of incision. Selective Hepatic Intra-arterial Injection Abdominal pain, nausea, and vomiting are the most common reactions; other reactions include hepatic vein thrombosis, hepatic ischemia, liver enzymes abnormalities, transitory decrease in liver function, liver decompensation and renal insufficiency. Procedural risks include vascular complications and infections.
