Descriptions
Gadoterate injection is used a magnetic resonance imaging (MRI) contrast agent used to help create a clear picture of the body during an MRI scan. MRI scans use magnets and computers to create images of certain areas of the body. Unlike x-rays, MRI scans do not involve radiation. Gadoterate is a gadolinium-based contrast agent (GBCA) that is given by injection before an MRI to help diagnose problems in the brain, spine, head, neck, and other parts of the body.
This medicine is to be given only by or under the direct supervision of your doctor.
This product is available in the following dosage forms:
Before Using
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 performed to date have not demonstrated pediatric-specific problems that would limit the usefulness of gadoterate injection in newborns to children 17 years of age. However, safety and efficacy have not been established in preterm newborns.
Geriatric
Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of gadoterate injection in the elderly. However, elderly patients are more likely to have age-related kidney problems, which may require caution in patients receiving gadoterate.
Breastfeeding
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.
Drug Interactions
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.
Other Interactions
Certain medicines should not be used at or around the time of eating food or eating certain types of food since interactions may occur. Using alcohol or tobacco with certain medicines may also cause interactions to occur. Discuss with your healthcare professional the use of your medicine with food, alcohol, or tobacco.

Proper Use
A doctor or other trained health professional will give you or your child this medicine. It is given through an IV catheter that is placed into one of your veins just before you have an MRI scan.
This medicine comes with a Medication Guide. Read and follow these instructions carefully. Ask your doctor if you have any questions.
Precautions
It is very important that your doctor check you or your child's progress while you are receiving this medicine and during the MRI scan to make sure this medicine is working properly. Blood and urine tests may be needed to check for unwanted effects.
This medicine should not be given intrathecally (injection given through the spinal canal). It may cause serious unwanted effects including agitation, back pain, blurred vision, change or loss of consciousness, confusion, death, dizziness, drowsiness, fever, hallucinations, headache, irritability, mood or metal changes, seizures, stiff neck, unusual tiredness or weakness, or vomiting when given intrathecally.
Check with your doctor or nurse right away if you or your child have burning or itching of the skin, deep bone pain in the hips or ribs, joint stiffness, a limited range of motion in the arms and legs, muscle weakness, red or dark patches on the skin of the arms or legs, or skin swelling, hardening, or tightening within the first few days or weeks after you receive this medicine. These may be symptoms of a very serious disease called nephrogenic systemic fibrosis (NSF).
This medicine may cause a serious allergic reaction called anaphylaxis, which can be life-threatening and requires immediate medical attention. Tell your doctor right away if you have a rash, itching, hoarseness, trouble breathing, trouble swallowing, or any swelling of your hands, face, or mouth after receiving the medicine.
This medicine contains a metal called gadolinium, which can stay in your body (including the brain, bones, skin) for a long time (several months to years). Talk to your doctor if you have concerns.
This medicine may increase your risk of having acute kidney injury requiring dialysis. This has occurred in patients with severe kidney problems, and the risk is increased with high doses of gadoterate injection. Talk to your doctor about this risk.
Tell your doctor right away if you or your child have mild, burning pain, feeling of warmth or coldness, peeling of the skin, redness, or swelling at the injection site.
