Gadoteridol Injection is a gadolinium-based contrast agent indicated for magnetic resonance imaging (MRI) to visualize: lesions with disrupted blood brain barrier and/or abnormal vascularity in the brain (intracranial lesions), spine and associated tissues in adults and pediatric patients, including term neonates (1.1 ) lesions in the head and neck in adults ( 1.2 ) 1.1 MRI of the Central Nervous System (CNS) Gadoteridol Injection is indicated for magnetic resonance imaging (MRI) in adults and pediatric patients including term neonates to visualize lesions with disrupted blood brain barrier and/or abnormal vascularity in the brain (intracranial lesions), spine and associated tissues. 1.2 MRI of Extracranial/Extraspinal Head and Neck Gadoteridol Injection is indicated for MRI in adults to visualize lesions in the head and neck.

Gadoteridol Injection is contraindicated in patients with known allergic or hypersensitivity reactions to Gadoteridol Injection [see Warnings and Precautions ( 5.3 )] . Allergic or hypersensitivity reactions to Gadoteridol Injection ( 4 )

Hypersensitivity: anaphylactic/anaphylactoid reactions with cardiovascular, respiratory and cutaneous manifestations, ranging from mild to severe reactions including shock can occur. Monitor patients closely for need of emergency cardiorespiratory support ( 5.3 ) Gadolinium is retained for months or years in brain, bone, and other organs. ( 5.4 ) 5.1 Risk Associated with Intrathecal Use Intrathecal administration of GBCAs can cause serious adverse reactions including death, coma, encephalopathy, and seizures. The safety and effectiveness of Gadoteridol injection have not been established with intrathecal use. Gadoteridol injection is not approved for intrathecal use [see Dosage and Administration ( 2.1 ) ]. 5.2 Nephrogenic Systemic Fibrosis GBCAs increase the risk for nephrogenic systemic fibrosis (NSF) among patients with impaired elimination of the drugs. Avoid use of Gadoteridol injection among these patients unless the diagnostic information is essential and not available with non-contrast MRI or other modalities. The GBCA-associated NSF risk appears highest for patients with chronic, severe kidney disease (GFR less than 30 mL/min/1.73 m 2 ) as well as patients with acute kidney injury. The risk appears lower for patients with chronic, moderate kidney disease (GFR 30 - 59 mL/min/1.73 m 2 ) and little, if any, for patients with chronic, mild kidney disease (GFR 60 - 89 mL/min/1.73 m 2 ). NSF may result in fatal or debilitating fibrosis affecting the skin, muscle and …

8.1 Pregnancy Risk Summary GBCAs cross the placenta and result in fetal exposure and gadolinium retention. The human data on the association between GBCAs and adverse fetal outcomes are limited and inconclusive (see Data ) . Because of the potential risks of gadolinium to the fetus, use Gadoteridol Injection only if imaging is essential during pregnancy and cannot be delayed. In animal reproduction studies in rats, gadoteridol doubled the incidence of post-implantation loss at up to 16 times the recommended human dose (RHD). There were no adverse developmental effects observed in rabbits with intravenous administration of gadoteridol during organogenesis at doses up to 19 times the …
