Gadofosveset

Generic name: Gadofosveset
Drug class: Magnetic resonance imaging contrast media

Usage of Gadofosveset

Gadofosveset is a contrast agent. It is used in magnetic resonance angiography (MRA) to help create a clear picture of the blood vessels (arteries). The MRA scan is a special kind of diagnostic procedure. It uses magnets and computers to create images or “pictures” of the blood vessels in certain areas of the body. Gadofosveset is a gadolinium-based contrast agent (GBCA).

Gadofosveset is given by injection before MRA to help diagnose problems in the blood vessels (e.g., blockage of the arteries).

This medicine is to be used only by or under the direct supervision of a doctor.

Before taking Gadofosveset

In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For this medicine, the following should be considered:

Allergies

Tell your doctor if you have ever HAD any unusual or allergic Reaction to this medicine or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.

Pediatric

Appropriate studies have not been performed on the relationship of age to the effects of gadofosveset in the pediatric population. Safety and efficacy have not been established.

Geriatric

Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of gadofosveset in the elderly. However, elderly patients are more likely to have age-related kidney problems, which may require caution and an adjustment in the dose for patients receiving gadofosveset.

There are no adequate studies in women for determining infant risk when using this medication during breastfeeding. Weigh the potential benefits against the potential risks before taking this medication while breastfeeding.

Interactions with Medicines

Although certain medicines should not be used together at all, in other cases two different medicines may be used together even if an interaction might occur. In these cases, your doctor may want to change the dose, or other precautions may be necessary. Tell your healthcare professional if you are taking any other prescription or nonprescription (over-the-counter [OTC]) medicine.

Interactions with Food/Tobacco/Alcohol

Certain medicines should not be used at or around the time of eating food or eating certain types of food since interactions may occur.
