MEDICATION GUIDE
OMNISCAN™ (OMNI-scan)
(gadodiamide)
Injection for intravenous use

What is OMNISCAN?

  • OMNISCAN is a prescription medicine called a gadolinium-based contrast agent (GBCA). OMNISCAN, like other GBCA medicines, is used with a magnetic resonance imaging (MRI) scanner.
  • An MRI exam with a GBCA, including OMNISCAN, helps your doctor to see problems better than an MRI exam without a GBCA.
  • Your doctor has reviewed your medical records and has determined that you would benefit from using a GBCA with your MRI exam.

What is the most important information I should know about OMNISCAN?

  • OMNISCAN contains a metal called gadolinium. Small amounts of gadolinium can stay in your body including the brain, bones, skin and other parts of your body for a long time (several months to years).
  • It is not known how gadolinium may affect you, so far, studies have not found harmful effects in patients with normal kidneys.
  • Rarely, patients have reported pains, tiredness, and skin, muscle or bone ailments for a long time, but these symptoms have not been directly linked to gadolinium.
  • There are different GBCAs that can be used for your MRI exam. The amount of gadolinium that stays in the body is different for different gadolinium medicines. Gadolinium stays in the body more after Omniscan or Optimark than after Eovist, Magnevist, or MultiHance. Gadolinium stays in the body the least after Dotarem, Gadavist, or ProHance.
  • People who get many doses of gadolinium medicines, women who are pregnant and young children may be at increased risk from gadolinium staying in the body.
  • Some people with kidney problems who get gadolinium medicines can develop a condition with severe thickening of the skin, muscles and other organs in the body (nephrogenic systemic fibrosis). Your healthcare provider should screen you to see how well your kidneys are working before you receive OMNISCAN.

Do not receive OMNISCAN if you have had a severe allergic reaction to OMNISCAN.

Before receiving OMNISCAN, tell your healthcare provider about all your medical conditions, including if you:

  • have had any MRI procedures in the past where you received a GBCA. Your healthcare provider may ask you for more information including the dates of these MRI procedures.
  • are pregnant or plan to become pregnant. It is not known if OMNISCAN can harm your unborn baby. Talk to your healthcare provider about the possible risks to an unborn baby if a GBCA such as OMNISCAN is received during pregnancy
  • have kidney problems, diabetes, or high blood pressure.
  • have had an allergic reaction to dyes (contrast agents) including GBCAs
