Gadodiamide

⛔ FDA Black Box Warning

WARNING: RISK ASSOCIATED WITH INTRATHECAL USE and NEPHROGENIC SYSTEMIC FIBROSIS WARNING: RISK ASSOCIATED WITH INTRATHECAL USE and NEPHROGENIC SYSTEMIC FIBROSIS See full prescribing information for complete boxed warning. Intrathecal administration of gadolinium-based contrast agents (GBCAs) can cause serious adverse reactions including death, coma, encephalopathy, and seizures. OMNISCAN is not approved for intrathecal use ( 5.1 ). GBCAs increase the risk for nephrogenic systemic fibrosis among patients with impaired elimination of the drugs. Avoid use of OMNISCAN in these patients unless the diagnostic information is essential and not available with non-contrasted MRI or other modalities. Do not administer OMNISCAN to patients with: chronic, severe kidney disease (GFR < 30 mL/min/1.73m 2 ), or acute kidney injury ( 4 ). Screen patients for acute kidney injury and other conditions that may reduce renal function. For patients at risk for chronically reduced renal function (e.g., age > 60 years, hypertension or diabetes), estimate the glomerular filtration rate (GFR) through laboratory testing ( 5.2 ). Risk Associated with Intrathecal Use Intrathecal administration of gadolinium-based contrast agents (GBCAs) can cause serious adverse reactions including death, coma, encephalopathy, and seizures. OMNISCAN is not approved for intrathecal use [see Warnings and Precautions (5.1) ]. Nephrogenic Systemic Fibrosis GBCAs increase the risk for nephrogenic systemic fibrosis (NSF) among patients with impaired elimination of the drugs. Avoid use of OMNISCAN in these patients unless the diagnostic information is essential and not available with non-contrasted MRI or other modalities. NSF may result in fatal or debilitating fibrosis affecting the skin, muscle and internal organs. Do not administer OMNISCAN to patients with: chronic, severe kidney disease (GFR < 30 mL/min/1.73m 2 ), or acute kidney injury [see Contraindications (4) ]. Screen patients for acute kidney injury and other

Contraindications

4 CONTRAINDICATIONS OMNISCAN is contraindicated in patients with: Chronic, severe kidney disease (glomerular filtration rate, GFR < 30 mL/min/1.73m 2 ) or acute kidney injury Prior hypersensitivity to OMNISCAN Patients with chronic, severe kidney disease (GFR < 30 mL/min/1.73m 2 ) or acute kidney injury ( 4 ).

Pregnancy & Breastfeeding

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, no adverse fetal effects were observed with administration of gadodiamide to pregnant rats during organogenesis at doses 1.3 times the maximum human dose based on body surface area (see Data ) . Because of the potential risks of gadolinium to the fetus, use OMNISCAN only if imaging is essential during pregnancy and cannot be delayed. The estimated background risk of major birth defects and miscarriage for the indicated population(s) are unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively. Data Human Data Contrast enhancement is visualized in the human placenta and fetal tissues after maternal GBCA administration. Cohort studies and case reports on exposure to GBCAs during pregnancy have not reported a clear association between GBCAs and adverse effects in the exposed neonates. However, a retrospective cohort study, comparing pregnant women who had a GBCA MRI to pregnant women who did not have an MRI, reported a higher occurrence of stillbirths and neonatal deaths in the group receiving GBCA MRI. Limitations of this study include a lack of comparison with non-contrast MRI and lack of information about the maternal indication for MRI. Overall, these data preclude a reliable evaluation of the potential risk of adverse fetal outcomes with the use of GBCAs in pregnancy. Animal Data Gadolinium Retention GBCAs administered to pregnant non-human primates (0.1 mmol/kg on gestational days 85 and 135) result in measurable gadolinium concentration in the offspring in bone, brain, skin, liver, kidney
