Iodixanol (contrast agent) (Iodixanol) — Uses, Dosage, Side Effects & Safety

Drug class: Diagnostics, Procedures & Systems

Overview

Iodixanol is a contrast agent used to enhance the visibility of blood vessels, organs, and tissues during medical imaging procedures such as X-rays, computed tomography (CT) scans, and angiography. It helps healthcare providers obtain clearer images to diagnose and monitor various conditions, including heart disease, blood vessel disorders, and cancers. Iodixanol works by temporarily increasing the contrast of the area being examined, making it easier to distinguish between normal and abnormal structures. It is injected into a vein or artery just before or during the imaging procedure. Key points for patients: Iodixanol is generally well-tolerated, but it is important to inform your healthcare provider about any allergies, kidney problems, or previous reactions to contrast agents. You may be asked to fast before the procedure and to drink plenty of fluids afterward to help flush the contrast from your body.

Can Iodixanol cause allergic reactions?

Yes, allergic reactions can occur, ranging from mild rash to severe anaphylaxis. Inform your healthcare provider if you have a history of allergies to contrast agents or other medications.

Do I need to stop taking metformin before receiving iodixanol?

If you are taking metformin, your doctor may advise you to temporarily stop it before and after the procedure to reduce the risk of lactic acidosis, especially if you have kidney impairment.

How long does iodixanol stay in the body?

Iodixanol is usually eliminated from the body within 24 hours in people with normal kidney function. It may take longer in those with kidney problems.

Can I breastfeed after receiving iodixanol?
