Warnings and precautions
Serious Warnings and Precautions
Gadolinium-based contrast agents (such as Omniscan) increase the risk of a rare disease called Nephrogenic Systemic Fibrosis (NSF) in patients with:
- severe kidney disease or acute kidney injury
- mmature renal function, such as newborns and infants
Your doctor will monitor your health after administering Omniscan, if you are considered to be at risk for developing NSF.
BEFORE you are given Omniscan talk to your doctor if any of the following situations apply to you. The doctor will decide whether the intended examination is possible or not:
- You are pregnant or could be pregnant
- You are breastfeeding or intend to breastfeed
- You have sickle cell disease
- You have poor kidney function or kidney problems
- You have diabetes
- You have high blood pressure
- You have seizures
- You are allergic or have had a hypersensitivity (allergic) reaction to contrast media products similar to Omniscan
There have been post-market reports of a rare disease called Nephrogenic Systemic Fibrosis (NSF) following gadolinium-based contrast agent (GBCA) use.
NSF is a rare condition which has only been observed so far in patients with severe kidney disease. At present, there is no evidence that other patient groups are at risk of developing the condition. Due to NSF the skin becomes thickened, coarse and hard, which sometimes makes bending of the joints difficult. NSF may spread to other organs and even cause death.
Patients with severe kidney disease should avoid the use of Omniscan unless the health care professional believes the possible benefits outweigh the potential risks. Those who have already had an MR imaging procedure and who have any of the following symptoms should seek medical attention as soon as possible:
- Swelling, hardening and tightening of the skin
- Reddened or darkened patches on the skin
- Burning or itching of the skin
- Yellow spots on the whites of the eyes
- Stiffness in the joints, problems moving or straightening arms, hands, legs or feet
- Pain deep in the hip bone or ribs
- Weakness of the muscles
Accumulation of gadolinium in the brain
Recent information shows that gadolinium (as in Omniscan) may build up in the brain after multiple uses and:
- The effect on the brain is unknown right now.
- Your doctor will:
- carefully consider whether to use repeated doses
- use the lowest dose
Interactions with this medication
Drug interaction studies have not been done with Omniscan.
