Generic name: gadodiamide (intravenous route) [ gad-oh-DYE-a-mide ]
Drug class: Magnetic resonance imaging contrast media
Medically reviewed by Drugs.com. Last updated on Feb 1, 2023.
Gadodiamide is not for intrathecal use. Inadvertent intrathecal use has caused convulsions, coma, and sensory and motor neurologic deficits. Gadolinium-based contrast agents (GBCAs) increase the risk for nephrogenic systemic fibrosis (NSF) among patients with impaired elimination of the drugs Avoid use of GBCAs unless the diagnostic information is essential and not available with non-contrast enhanced MRI. NSF may result in fatal or debilitating systemic fibrosis affecting the skin, muscle, and internal organs. Do not administer to patients with chronic, severe kidney disease (GFR less than 30 mL/min/1.73 m(2)) or acute kidney injury. 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 Omniscan
Gadodiamide injection is used to help diagnose or find problems in the brain, spine, chest, stomach, hip area, and other parts of your body. It is a gadolinium-based contrast agent (GBCA) used in magnetic resonance imaging (MRI) scans. Contrast agents are used to help create a clear picture of the different parts of the body during MRI scans. MRI scans use magnets and computers to create images or “pictures” of certain areas inside the body. Unlike x-rays, they do not involve ionizing radiation.
This medicine is to be used only by or under the direct supervision of your doctor.
Before using Omniscan
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:
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.
Appropriate studies performed to date have not demonstrated pediatric-specific problems that would limit the usefulness of gadodiamide injection in children 2 years of age and older. However, safety and efficacy have not been established in children younger than 2 years of age.
Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of gadodiamide injection in the elderly. However, elderly patients are more likely to have age-related liver, kidney, or heart problems, which may require caution and an adjustment in the dose for patients receiving gadodiamide.
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. 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.

The presence of other medical problems may affect the use of this medicine. Make sure you tell your doctor if you have any other medical problems, especially:
- Asthma or allergies, history of or
- Patients who have had previous reactions to contrast media—Use with caution. May increase the likelihood of an allergic reaction.
- Diabetes or
- Hypertension (high blood pressure) or
- Infection, severe—Use with caution. May increase risk for kidney problems.
- Kidney disease, mild or moderate—Use with caution. May increase the chance for more serious side effects.
- Kidney problems, severe (recent or long-term)—Should not be used in patients with this condition.
Proper use of Omniscan
A doctor or other trained health professional will give you or your child this medicine in a medical facility. It is given through a needle 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 while using Omniscan
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.
The risk of having a very serious disease called nephrogenic systemic fibrosis (NSF) is increased in patients with severe kidney disease. Even if you have severe kidney problems, your doctor may decide that it is still important to receive this medicine. Check with your doctor right away if you or your child have burning, swelling, tightening, or itching of the skin, red or dark patches on the skin, joint stiffness, limited range of motion in the arms and legs, pain that is deep in the hip bone or ribs, or muscle weakness. These may be symptoms of NSF.
This medicine may cause a serious type of allergic reaction called anaphylaxis, which can be life-threatening and requires immediate medical attention. Check with your doctor or nurse right away if you or your child 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 is more likely in patients with a history of kidney problems or in patients receiving increasing 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.
Make sure your doctor knows that you or your child have used this medicine. This medicine may affect the results of certain medical tests (eg, serum iron or calcium).
