Clariscan is a gadolinium-based contrast agent indicated for intravenous use with magnetic resonance imaging (MRI) in brain (intracranial), spine and associated tissues in adult and pediatric patients (including term neonates) to detect and visualize areas with disruption of the blood brain barrier (BBB) and/or abnormal vascularity.

History of clinically important hypersensitivity reactions to Clariscan [see Warnings and Precautions (5.3) ]. Clinically important hypersensitivity reactions to Clariscan. ( 4 )

Hypersensitivity Reactions: Anaphylactoid/anaphylactic reactions with cardiovascular, respiratory or cutaneous manifestations, ranging from mild to severe, including death, have uncommonly occurred. Monitor patients closely for need of emergency cardiorespiratory support. ( 5.3 ) Gadolinium Retention: 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 Clariscan have not been established with intrathecal use. Clariscan 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 Clariscan 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 < 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 to 59 mL/min/1.73 m 2 ) and little, if any, for patients with chronic, mild kidney disease (GFR 60 to 89 mL/min/1.73 m 2 ). NSF may result in fatal or debilitating fibrosis affecting the skin, muscle, and internal …

8.1 Pregnancy Risk Summary GBCAs cross the human 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 ) . In animal reproduction studies, there were no adverse developmental effects observed in rats or rabbits with intravenous administration of gadoterate meglumine during organogenesis at doses of 16 and 10 times, respectively, the recommended human dose (see Data ) . Because of the potential risks of gadolinium to the fetus, use Clariscan only if imaging is essential during pregnancy and cannot be delayed. The estimated background risk of major birth defects and …
