When This Medicine Should Not Be Used:Make sure your doctor and the person who gives you this medicine know if you have had an allergic reaction to any contrast dye.
How to Use This Medicine:
- Your doctor will prescribe your exact dose and tell you how often it should be given. This medicine can be given different ways, depending on what part of your body the doctor needs to see. This medicine may be given through a needle or catheter (plastic tube) placed in one of your veins.
- A nurse or other health provider will give you this medicine.
- You might also receive other medicine before you are given the contrast dye.
- Tell your caregiver right away if any of this medicine gets on your skin. A caregiver might need to take your blood pressure, temperature, or pulse during the test.
- You might need to stay for awhile after the test is done.
Drugs and Foods to Avoid:
Ask your doctor or pharmacist before using any other medicine, including over-the-counter medicines, vitamins, and herbal products.
- Make sure your doctor knows about all other medicines you are using. Different contrast dyes have different drug and food concerns. Some other things that affect other drugs and foods are what kind of test is being done and what part of your body is being tested.
- Make sure your doctor knows if you are also using a blood thinner such as warfarin (Coumadin®).
Warnings While Using This Medicine:
- Make sure your doctor knows if you are pregnant or breastfeeding.
- Make sure your doctor knows if you have severe kidney problems or liver disease. Also tell your doctor if you have just had a liver transplant or if you are going to have a transplant. The use of a gadolinium-based contrast agent (GBCA) during an MRI should be avoided in patients with severe kidney problems, patients with severe kidney problems due to a severe liver disorder (hepato-renal syndrome), or patients with severe kidney problems before, during, or after a liver transplant. The risk of nephrogenic systemic fibrosis (NSF), a very serious disease affecting the skin, muscle, and internal organs, may be increased. Your doctor may do some tests before your MRI to make sure your kidneys are working properly. Even if you have kidney problems or liver disease, your doctor may decide that it is still important to use the contrast dye. If you are on hemodialysis and treated with this contrast dye, your doctor may perform hemodialysis immediately after you receive the contrast agent.
- Tell your doctor and the person who does the test if you are allergic to iodine, or if you have asthma or any type of allergy. This includes hay fever and food allergy.
- Make sure your health caregiver knows if you have diabetes, sickle cell disease, thyroid problems, or pheochromocytoma (a tumor on the adrenal gland). Tell your caregiver if you have cancer, especially if you have multiple myeloma. Make sure your doctor knows if you have high blood pressure, blood circulation problems, or heart disease.
- Tell any doctor or dentist who treats you that you are using this medicine. This medicine may affect certain medical test results.
- The specific test you are having might have its own side effects or risks. Talk with you health caregiver about the test and what you should expect during and after the test.
