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

Drug class: Diagnostics, Procedures & Systems

Overview

Ioversol is a contrast agent used to enhance the visibility of blood vessels, organs, and tissues during imaging procedures such as CT scans, angiography, and urography. It contains iodine, which helps X-ray images appear clearer and more detailed. This medication is administered by a healthcare professional, usually through an injection into a vein or artery. Ioversol is designed to be less likely to cause allergic reactions or discomfort compared to older, high-osmolar contrast agents. Patients should inform their healthcare provider about any allergies, kidney problems, or previous reactions to contrast agents before receiving Ioversol. Staying well-hydrated before and after the procedure can help reduce the risk of kidney-related side effects.

Therapeutic uses

• Angiography (e.g., cerebral, peripheral, coronary)
