Overview
Iohexol is a nonionic radiographic contrast agent available as: OMNIPAQUE (iohexol) injection for intrathecal, intra-arterial, intravenous, oral, rectal, intraarticular, and body cavity use OMNIPAQUE (iohexol) oral solution for oral use The chemical name of iohexol is Bis(2,3-dihydroxypropyl)-5-[ N -(2,3-dihydroxypropyl)-acetamido]-2,4,6- triiodoisophthalamide with a molecular weight of 821.14 (iodine content 46.36%). Iohexol has the following structural formula: OMNIPAQUE injection is a sterile, pyrogen-free, colorless to pale yellow solution available in five concentrations of iodine: OMNIPAQUE 140 mg iodine/mL: Each mL contains 302 mg iohexol (providing 140 mg organically bound iodine) and the following inactive ingredients: 0.1 mg edetate calcium disodium and 1.21 mg tromethamine. OMNIPAQUE 180 mg iodine/mL: Each mL contains 388 mg iohexol (providing 180 mg organically bound iodine) and the following inactive ingredients: 0.1 mg edetate calcium disodium and 1.21 mg tromethamine. OMNIPAQUE 240 mg iodine/mL: Each mL contains 518 mg iohexol (providing 240 mg organically bound iodine) and the following inactive ingredients: 0.1 mg edetate calcium disodium and 1.21 mg tromethamine. OMNIPAQUE 300 mg iodine/mL: Each mL contains 647 mg iohexol (providing 300 mg organically bound iodine) and the following inactive ingredients: 0.1 mg edetate calcium disodium and 1.21 mg…
How to use
For each imaging procedure, specific dosage forms, concentrations, and presentations are recommended. Individualize the concentration and volume according to the specific dosing tables and accounting for factors such as age, body weight, and condition of the patient, and the equipment and imaging technique used. ( 2.2 , 2.3 , 2.4 , 2.5 , 2.6 , 2.7 , 2.8 , 2.9 ) See full prescribing information for complete dosing and administration information. ( 2 ) 2.1 Important Dosage and Administration Instructions Specific dosage forms, concentrations, and presentations of OMNIPAQUE are recommended for each type of imaging procedure [see Dosage and Administration (2.2 , 2.3 , 2.4 , 2.5 , 2.6 , 2.7 , 2.8 , 2.9) and Warnings and Precautions (5.1 , 5.2) ]. Individualize the volume, strength, and rate of administration of OMNIPAQUE injection according to the specific dosing tables [see Dosage and Administration (2.2 , 2.3 , 2.4 , 2.5 , 2.6 , 2.7 , 2.8 , 2.9) ] . Consider factors such as age, body weight, vessel size, blood flow rate within the vessel, anticipated pathology, degree and extent of opacification required, structures or area to be examined, disease processes affecting the patient, and equipment and technique to be employed. Hydrate patients before and after administration of OMNIPAQUE injection [see Warnings and Precautions (5.4) ]. Use aseptic technique for all handling and…

Warnings
Important safety information
WARNING: RISKS ASSOCIATED WITH INTRATHECAL ADMINISTRATION OF OMNIPAQUE INJECTION 140 mg IODINE/mL and 350 mg IODINE/mL Use only the OMNIPAQUE iodine concentrations and presentations recommended for intrathecal procedure [see Dosage and Administration (2.2 , 2.8) ]. Intrathecal administration of OMNIPAQUE of a wrong iodine concentration, even if inadvertent, may cause death, convulsions, seizures, cerebral hemorrhage, coma, paralysis, arachnoiditis, acute renal failure, cardiac arrest, rhabdomyolysis, hyperthermia, and brain edema [see Warnings and Precautions (5.1) ]. WARNING: RISKS ASSOCIATED WITH INTRATHECAL ADMINISTRATION OF OMNIPAQUE INJECTION 140 and 350 mg IODINE/mL Use only the iodine concentrations and presentations recommended for intrathecal procedures. Intrathecal administration of a wrong iodine concentration, even if inadvertent, may cause death, convulsions, seizures, cerebral hemorrhage, coma, paralysis, arachnoiditis, acute renal failure, cardiac arrest, rhabdomyolysis, hyperthermia, and brain edema. ( 2.2 , 2.8 , 5.1 )
Interactions
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, OMNIPAQUE 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 OMNIPAQUE may interfere with thyroid uptake of radioactive iodine (I-131 and I-123) and decrease therapeutic and diagnostic efficacy. Avoid thyroid therapy or testing for up to 6 weeks post OMNIPAQUE. 7.2 Drug-Laboratory Test Interactions Protein-Bound Iodine Test Iodinated contrast agents, including OMNIPAQUE, will temporarily increase protein-bound iodine in blood. Do not perform protein-bound iodine test for at least 16 days following administration of OMNIPAQUE. However, thyroid function tests that do not depend on iodine estimation, e.g., T 3 resin uptake or direct thyroxine assays, are not affected.
