gadofosveset (Injection route)
Gadolinium-based contrast agents (GBCAs) increase the risk for nephrogenic systemic fibrosis (NSF) in patients with impaired elimination of the drugs (ie, chronic, severe renal insufficiency (GFR less than 30 mL/min/1.73 m(2)), or acute kidney injury. Avoid use of GBCAs unless the diagnostic information is essential and not available with non-contrast enhanced MRI. Screen all patients for acute kidney injury and other conditions that may reduce renal function. For patients at risk for chronically reduced renal function (eg, age greater than 60 years, hypertension, or diabetes), perform lab testing to estimate the GFR. For patients with the highest NSF risk, do not exceed recommended dose and allow a sufficient time period for elimination prior to readministration .

Uses For 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).
gadofosveset is to be used only by or under the direct supervision of a doctor.
Before Using 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 gadofosveset, the following should be considered:
Tell your doctor if you have ever had any unusual or allergic reaction to gadofosveset 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.
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.
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.
