Iohexol, sold under the trade name Omnipaque among others, is a contrast agent used during X-rays. This includes when visualizing arteries, veins, ventricles of the brain, the urinary system, and joints, as well as during computer tomography (CT scan). It is given by mouth, injection into a vein, or into a body cavity.

Side effects include vomiting, skin flushing, headache, itchiness, kidney problems, and low blood pressure. Less commonly allergic reactions or seizures may occur. Allergies to povidone-iodine or shellfish do not affect the risk of side effects more than other allergies. Use in the later part of pregnancy may cause hypothyroidism in the baby. Iohexol is an iodinated non-ionic radiocontrast agent. It is in the low osmolar family.

Iohexol was approved for medical use in 1985. It is on the World Health Organization's List of Essential Medicines. The wholesale cost in the developing world is about US$10.99 per 50 ml vial. In the United States a dose costs US$50–100.
