What is gadoversetamide?

Gadoversetamide is a contrast agent with magnetic properties. It is used in combination with magnetic resonance imagining (MRI) to allow blood vessels, organs, and other non-bony tissues to be seen more clearly on the MRI.

Gadoversetamide is used to help diagnose certain disorders of the brain and spine (central nervous system), or the liver.

Gadoversetamide may also be used for purposes not listed in this medication guide.


Gadoversetamide can cause a life-threatening condition in people with advanced kidney disease. You should not receive this medication if you have kidney disease or if you are on dialysis.

How is gadoversetamide given?

Gadoversetamide is given as an infusion into a vein. A healthcare provider will give you this injection.

Your doctor or other healthcare provider may want to watch you for a short time after your test is over. This is to make sure you do not have any unwanted side effects or delayed reactions.

Gadoversetamide can affect the results of certain medical tests for up to 24 hours after your MRI. Tell any doctor who treats you that you have received gadoversetamide.

What happens if I miss a dose?

Since gadoversetamide is used only during your MRI, you will not be on a dosing schedule.

What happens if I overdose?

Since this medication is given by a healthcare professional in a medical setting, an overdose is unlikely to occur.

What should I avoid after receiving gadoversetamide?

Follow your doctor's instructions about any restrictions on food, beverages, or activity.
