FDA Warnings

GADODIAMIDE

5 WARNINGS AND PRECAUTIONS Hypersensitivity Reactions: Anaphylactoid and other serious hypersensitivity reactions including fatal reactions have occurred particularly in patients with history of allergy or drug reactions
1 Risk Associated with Intrathecal Use Intrathecal administration of GBCAs can cause serious adverse reactions including death, coma, encephalopathy, and seizures
2 Nephrogenic Systemic Fibrosis GBCAs increase the risk for nephrogenic systemic fibrosis (NSF) among patients with impaired elimination of the drugs
The GBCA-associated NSF risk appears highest for patients with chronic, severe kidney disease (GFR 60 years, diabetes mellitus or chronic hypertension), estimate the GFR through laboratory testing

IODIXANOL

5 WARNINGS AND PRECAUTIONS Hypersensitivity Reactions: Life-threatening or fatal reactions can occur
Minimize dose and maintain adequate hydration to minimize risk
4 ) Thyroid Dysfunction in Pediatric Patients 0 to 3 Years of Age: Individualize thyroid function monitoring based on risk factors such as prematurity
1 Risks Associated with Inadvertent Intrathecal Administration Iodixanol is for intravascular use only and is contraindicated for intrathecal use [see Contraindications (4) and Dosage and Administration (2
