Warnings

Black Box Warnings

Not for intrathecal (IT) use; inadvertent IT administration has caused convulsions, coma, sensory and motor neurologic deficits

Risk for nephrogenic systemic fibrosis (NSF) with acute or chronic renal insufficiency (GFR <30 mL/min/1.73m²), hepatorenal syndrome, or acute renal insufficiency resulting from perioperative liver transplant

NSF affects internal organs, skin, and muscle and can be fatal

Only use if essential and MRI cannot not provide appropriate diagnostic image

Screen for renal dysfunction, do not exceed recommended dosage, and allow for drug elimination before giving subsequent doses

Contraindications

Acute kidney disease or chronic, severe kidney disease (ie, GFR <30 mL/min/1.73m²); use associated with increased risk for nephrogenic systemic fibrosis (NSF)

Hypersensitivity

Cautions

Not for intrathecal use (see Black Box Warnings)

Anemia, hepatic/renal impairment

Acute renal failure has occurred in patients with pre-existing renal insufficiency; use the lowest necessary dose and evaluate renal function

Nephrogenic systemic fibrosis (NSF) reported in patients with impaired elimination; higher than recommended dosing or repeat dosing appears to increase the risk

Anaphylactoid and anaphylactic reactions with cardiovascular, respiratory and/or cutaneous manifestations, resulting in death have occurred

Brain deposits

  • 7/28/2015: FDA is investigating the risk of brain deposits following repeated use of gadolinium-based contrast agents (GBCAs) for MRI
  • Recent publications in the medical literature have reported that deposits of GBCAs remain in the brains of some patients who undergo ≥4 contrast MRI scans, long after the last administration
  • It is unknown whether these gadolinium deposits are harmful or can lead to adverse health effects
  • Early data in rat studies show that linear GBCAs are more prone to dissociation into free gadolinium and demonstrate greater brain deposition than macrocyclic GBCAs, which are less prone to dissociation

Pregnancy & Lactation

Pregnancy Category: C

Lactation: not known whether excreted in breast milk, use caution

Pregnancy Categories

A:Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.

B:May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk.

C:Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done.

D:Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk.

X:Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist.

NA:Information not available.
