🚨 Boxed Warning ▾
WARNING: RISK ASSOCIATED WITH INTRATHECAL USE and NEPHROGENIC SYSTEMIC FIBROSIS Risk Associated with Intrathecal Use Intrathecal administration of gadolinium-based contrast agents (GBCAs) can cause serious adverse reactions including death, coma, encephalopathy, and seizures. Gadoterate Meglumine Injection 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 Gadoterate Meglumine Injection 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. The risk for NSF appears highest among patients with: Chronic, severe kidney disease (GFR < 30 mL/min/1.73 m 2 ), or Acute kidney injury.
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, diabetes), estimate the glomerular filtration rate (GFR) through laboratory testing ( 5.1 ). For patients at highest risk for NSF, do not exceed the recommended Gadoterate Meglumine Injection dose and allow a sufficient period of time for elimination of the drug from the body prior to any re-administration [see Warnings and Precautions ( 5.2 )] .
WARNING: RISK ASSOCIATED WITH INTRATHECAL USE and NEPHROGENIC SYSTEMIC FIBROSIS See full prescribing information for complete boxed warning.

⛔ Contraindications ▾
4 CONTRAINDICATIONS History of clinically important hypersensitivity reactions to Gadoterate Meglumine Injection [see Warnings and Precautions ( 5.3 )] . Clinically important hypersensitivity reactions to Gadoterate Meglumine Injection. ( 4 )
⚠️ Warnings and Cautions ▾
5 WARNINGS AND PRECAUTIONS Hypersensitivity: 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 is retained for months or years in brain, bone, and other organs. ( 5.4 )
5.1Risk Associated with Intrathecal Use Intrathecal administration of GBCAs can cause serious adverse reactions including death, coma, encephalopathy, and seizures. The safety and effectiveness of Gadoterate Meglumine Injection have not been established with intrathecal use. Gadoterate Meglumine Injection is not approved for intrathecal use [see Dosage and Administration ( 2.1 )] .
5.2Nephrogenic Systemic Fibrosis GBCAs increase the risk for nephrogenic systemic fibrosis (NSF) among patients with impaired elimination of the drugs. Avoid use of gadoterate meglumine 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 < 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 internal organs. Report any diagnosis of NSF following Gadoterate Meglumine Injection administration to Slate Run Pharmaceuticals, LLC at 1-888-341-9214 or FDA (1-800-FDA-1088 or www.fda.gov/medwatch).
Screen patients for acute kidney injury and other conditions that may reduce renal function. Features of acute kidney injury consist of rapid (over hours to days) and usually reversible decrease in kidney function, commonly in the setting of surgery, severe infection, injury or drug-induced kidney toxicity. Serum creatinine levels and estimated GFR may not reliably assess renal function in the setting of acute kidney injury.
For patients at risk for chronically reduced renal function (e.g., age > 60 years, diabetes mellitus or chronic hypertension), estimate the GFR through laboratory testing. The factors that may increase the risk for NSF are repeated or higher than recommended doses of a GBCA and the degree of renal impairment at the time of exposure. Record the specific GBCA and the dose administered to a patient.
For patients at highest risk for NSF, do not exceed the recommended Gadoterate Meglumine Injection dose and allow a sufficient period of time for elimination of the drug prior to re-administration. For patients receiving hemodialysis, physicians may consider the prompt initiation of hemodialysis following the administration of a GBCA in order to enhance the contrast agent’s elimination. The usefulness of hemodialysis in the prevention of NSF is unknown [see Dosage and Administration ( 2 ) and Clinical Pharmacology ( 12 )] .
5.3Hypersensitivity Reactions Anaphylactic and anaphylactoid reactions have been reported with Gadoterate Meglumine Injection, involving cardiovascular, respiratory, and/or cutaneous manifestations. Some patients experienced circulatory collapse and died. In most cases, initial symptoms occurred within minutes of Gadoterate Meglumine Injection administration and resolved with prompt emergency treatment [see Adverse Reactions ( 6 )] .
Before Gadoterate Meglumine Injection administration, assess all patients for any history of a reaction to contrast media, bronchial asthma and/or allergic disorders. These patients may have an increased risk for a hypersensitivity reaction to Gadoterate Meglumine Injection. Administer Gadoterate Meglumine Injection only in situations where trained personnel and therapies are promptly available for the treatment of hypersensitivity reactions, includ…

6.1Clinical Studies Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in clinical practice. The data described below reflect Gadoterate Meglumine Injection exposure in 2867 patients, representing 2682 adults and 185 pediatric patients. Overall, 55% of the patients were men.
In clinical trials where ethnicity was recorded, the ethnic distribution was 81% Caucasian, 11% Asian, 4% Black, and 4% others. The average age was 53 years (range from < 1 week to 97 years). Overall, 4% of patients reported at least one adverse reaction, primarily occurring immediately or within 24 hours following Gadoterate Meglumine Injection administration.
Most adverse reactions were mild or moderate in severity and transient in nature. Table 2 lists adverse reactions that occurred in ≥ 0.2% patients who received Gadoterate Meglumine Injection. Table 2: Adverse Reactions in Clinical Trials Reaction Rate (%) n=2867 Nausea 0.6% Headache 0.4% Injection Site Pain 0.4% Injection Site Coldness 0.2% Rash 0.2% Adverse reactions that occurred with a frequency < 0.2% in patients who received Gadoterate Meglumine Injection include: feeling cold, feeling hot, burning sensation, somnolence, pain, dizziness, dysgeusia, blood creatinine increased, hypotension, hypertension, asthenia, fatigue, injection site reactions (inflammation, extravasation, pruritus, swelling, warmth), paresthesia, pruritus, laryngeal discomfort, pain in extremity, vomiting, anxiety and palpitations.
Adverse Reactions in Pediatric Patients During clinical trials, 185 pediatric patients (52 aged < 24 months, 33 aged 2 - 5 years, 57 aged 6 – 11 years and 43 aged 12 - 17 years) received Gadoterate Meglumine Injection.

👥 Use in Specific Populations ▾
8 USE IN SPECIFIC POPULATIONS Pregnancy: Use only if imaging is essential during pregnancy and cannot be delayed. ( 8.1 )
8.1Pregnancy 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 up to 16 and 10 times, respectively, the recommended human dose (see Data ) .
Because of the potential risks of gadolinium to the fetus, use Gadoterate Meglumine Injection 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 2-4% and 15-20% respectively. Data Human Data Contrast enhancement is visualized in the 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 material 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, and spleen for at least 7 months. GBCAs administered to pregnant mice (2 mmol/kg daily on gestational days 16 through 19) result in measurable gadolinium concentrations in the pups in bone, brain, kidney, liver, blood, muscle, and spleen at one month postnatal age. Reproductive Toxicology Gadoterate meglumine was administered in intravenous doses of 0, 2, 4 and 10 mmol/kg/day [3, 7 and 16 times the recommended human dose (RHD) based on body surface area (BSA)] to female rats for 14 days before mating, throughout the mating period and until gestation day (GD) 17.
Pregnant rabbits were administered gadoterate meglumine in intravenous doses of 0, 1, 3 and 7 mmol/kg/day (3, 10 and 23 times the RHD based on BSA) from GD6 to GD19. No effects on embryo-fetal development were observed at doses up to 10 mmol/kg/day in rats and 3 mmol/kg/day in rabbits. Maternal toxicity was observed in rats at 10 mmol/kg/day and in rabbits at 7 mmol/kg/day.
This maternal toxicity was characterized in rats by a slightly lower litter size and gravid uterus weight compared to the control group, and in rabbits by a reduction in body weight and food consumption.
8.2Lactation Risk Summary There are no data on the presence of gadoterate in human milk, the effects on the breastfed infant, or the effects on milk production. However, published lactation data on other GBCAs indicate that 0.01 to 0.04% of the maternal gadolinium dose is excreted in breast milk. Additionally, there is limited GBCA gastrointestinal absorption in the breast-fed infant.
Gadoterate is present in goat milk (see Data ) . The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for Gadoterate Meglumine Injection and any potential adverse effects on the breastfed infant from Gadoterate Meglumine Injecti…

🧒 Pediatric Use ▾
8.4Pediatric Use The safety and efficacy of Gadoterate Meglumine Injection at a single dose of 0.1 mmol/kg have been established in pediatric patients from birth (term neonates ≥ 37 weeks gestational age) to 17 years of age based on clinical data in 133 pediatric patients 2 years of age and older, and clinical data in 52 pediatric patients birth to less than 2 years of age that supported extrapolation from adult data [see Clinical Studies ( 14 )] . Adverse reactions in pediatric patients were similar to those reported in adults [see Adverse Reactions ( 6.1 )] .
No dosage adjustment according to age is necessary in pediatric patients [see Dosage and Administration ( 2.1 ), Pharmacokinetics ( 12.3 )] . The safety of Gadoterate Meglumine Injection has not been established in preterm neonates. No cases of NSF associated with Gadoterate Meglumine Injection or any other GBCA have been identified in pediatric patients age 6 years and younger [see Warnings and Precautions ( 5.2 )] .
Normal estimated GFR (eGFR) is approximately 30 mL/minute/1.73 m 2 at birth and increases to adult values by 2 years of age. Juvenile Animal Data Single and repeat-dose toxicity studies in neonatal and juvenile rats did not reveal findings suggestive of a specific risk for use in pediatric patients including term neonates and infants.
🧓 Geriatric Use ▾
8.5Geriatric Use In clinical studies of Gadoterate Meglumine Injection, 900 patients were 65 years of age and over, and 304 patients were 75 years of age and over. No overall differences in safety or efficacy were observed between these subjects and younger subjects. In general, use of Gadoterate Meglumine Injection in elderly patients should be cautious, reflecting the greater frequency of impaired renal function and concomitant disease or other drug therapy.
No age-related dosage adjustment is necessary.
🆘 Overdosage ▾
10 OVERDOSAGE Gadoterate Meglumine Injection administered to healthy volunteers and to adult patients at cumulative doses up to 0.3 mmol/kg was tolerated in a manner similar to lower doses. Adverse reactions to overdosage with Gadoterate Meglumine Injection have not been reported. Gadoterate meglumine can be removed from the body by hemodialysis [see Clinical Pharmacology (12.3)] .
🧬 Clinical Pharmacology ▾
12 CLINICAL PHARMACOLOGY
12.1Mechanism of Action Gadoterate is a paramagnetic molecule that develops a magnetic moment when placed in a magnetic field. The magnetic moment enhances the relaxation rates of water protons in its vicinity, leading to an increase in signal intensity (brightness) of tissues. In magnetic resonance imaging (MRI), visualization of normal and pathological tissue depends in part on variations in the radiofrequency signal intensity that occurs with: differences in proton density differences of the spin-lattice or longitudinal relaxation times (T1) differences in the spin-spin or transverse relaxation time (T2) When placed in a magnetic field, gadoterate shortens the T1 and T2 relaxation times in target tissues.
At recommended doses, the effect is observed with greatest sensitivity in the T1-weighted sequences.
12.2Pharmacodynamics Gadoterate affects proton relaxation times and consequently the MR signal, and the contrast obtained is characterized by the relaxivity of the gadoterate molecule. The relaxivity values for gadoterate are similar across the spectrum of magnetic field strengths used in clinical MRI (0.2-1.5 T). Disruption of the blood-brain barrier or abnormal vascularity allows distribution of gadoterate in lesions such as neoplasms, abscesses, and infarcts.
12.3Pharmacokinetics The pharmacokinetics of total gadolinium assessed up to 48 hours following an intravenously administered 0.1 mmol/kg dose of Gadoterate Meglumine Injection in healthy adult subjects demonstrated a mean elimination half-life (reported as mean ± SD) of about 1.4 ± 0.2 hr and 2.0 ± 0.7 hr in female and male subjects, respectively. Similar pharmacokinetic profile and elimination half-life values were observed after intravenous injection of 0.1 mmol/kg of Gadoterate Meglumine Injection followed 20 minutes later by a second injection of 0.2 mmol/kg (1.7 ± 0.3 hr and 1.9 ± 0.2 hr in female and male subjects, respectively).
Distribution The volume of distribution at steady state of total gadolinium in healthy subjects is 179 ± 26 and 211 ± 35 mL/kg in female and male subjects respectively, roughly equivalent to that of extracellular water. Gadoterate does not undergo protein binding in vitro . The extent of blood cell partitioning of gadoterate is not known.
Following GBCA administration, gadolinium is present for months or years in brain, bone, skin and other organs [see Warnings and Precautions ( 5.4 )] . Metabolism Gadoterate is not known to be metabolized. Elimination Following a 0.1 mmol/kg dose of Gadoterate Meglumine Injection, total gadolinium is excreted primarily in the urine with 72.9 ± 17.0% and 85.4 ± 9.7% (mean ± SD) eliminated within 48 hours, in female and male subjects, respectively.
Similar values were achieved after a cumulative dose of 0.3 mmol/kg (0.1 + 0.2 mmol/kg, 20 minutes later), with 85.5 ± 13.2% and 92.0 ± 12.0% recovered in urine within 48 hrs in female and male subjects respectively. In healthy subjects, the renal and total clearance rates of total gadolinium are comparable (1.27 ± 0.32 and 1.74 ± 0.12 mL/min/kg in females; and 1.40 ± 0.31 and 1.64 ± 0.35 mL/min/kg in males, respectively) indicating that the drug is primarily cleared through the kidneys. Within the studied dose range (0.1 to 0.3 mmol/kg), the kinetics of total gadolinium appear to be linear.
Specific Populations Renal Impairment A single intravenous dose of 0.1 mmol/kg of Gadoterate Meglumine Injection was administered to 8 patients (5 men and 3 women) with impaired renal function (mean serum creatinine of 498 ± 98 μmol/L in the 10-30 mL/min creatinine clearance group and 192 ± 62 μmol/L in the 30-60 mL/min creatinine clearance group). Renal impairment delayed the elimination of total gadolinium. Total clearance decreased as a function of the degree of renal impairment.
The distribution volume was unaffected by the severity of renal impairment (Table 5). No changes in renal function test parameters were observed after Gadoterate…
🧬 Mechanism of Action ▾
12.1Mechanism of Action Gadoterate is a paramagnetic molecule that develops a magnetic moment when placed in a magnetic field. The magnetic moment enhances the relaxation rates of water protons in its vicinity, leading to an increase in signal intensity (brightness) of tissues. In magnetic resonance imaging (MRI), visualization of normal and pathological tissue depends in part on variations in the radiofrequency signal intensity that occurs with: differences in proton density differences of the spin-lattice or longitudinal relaxation times (T1) differences in the spin-spin or transverse relaxation time (T2) When placed in a magnetic field, gadoterate shortens the T1 and T2 relaxation times in target tissues.
At recommended doses, the effect is observed with greatest sensitivity in the T1-weighted sequences.

💬 Medication Guide ▾
MEDICATION GUIDE Gadoterate Meglumine (gad” oh ter’ ate meg’ loo meen) Injection (gadoterate meglumine) Injection for intravenous use What is Gadoterate Meglumine Injection? Gadoterate Meglumine Injection is a prescription medicine called a gadolinium-based contrast agent (GBCA). Gadoterate Meglumine Injection, like other GBCAs, is injected into your vein and used with a magnetic resonance imaging (MRI) scanner.
An MRI exam with a GBCA, including Gadoterate Meglumine Injection, helps your doctor to see problems better than an MRI exam without a GBCA. Your doctor has reviewed your medical records and has determined that you would benefit from using a GBCA with your MRI exam. What is the most important information I should know about Gadoterate Meglumine Injection?
GBCAs like Gadoterate Meglumine Injection may cause serious side effects including death, coma, encephalopathy, and seizures when it is given intrathecally (injection given into the spinal canal). It is not known if Gadoterate Meglumine Injection is safe and effective with intrathecal use. Gadoterate Meglumine Injection is not approved for this use.
Gadoterate Meglumine Injection contains a metal called gadolinium. Small amounts of gadolinium can stay in your body including the brain, bones, skin and other parts of your body for a long time (several months to years). It is not known how gadolinium may affect you, but so far, studies have not found harmful effects in patients with normal kidneys.
Rarely patients have reported pains, tiredness, and skin, muscle or bone ailments for a long time, but these symptoms have not been directly linked to gadolinium. There are different GBCAs that can be used for your MRI exam. The amount of gadolinium that stays in the body is different for different gadolinium medicines.
Gadolinium stays in the body more after Omniscan or Optimark than after Eovist, Magnevist or MultiHance. Gadolinium stays in the body the least after Gadoterate Meglumine Injection, Gadavist or ProHance. People who get many doses of gadolinium medicines, women who are pregnant and young children may be at increased risk from gadolinium staying in the body.
Some people with kidney problems who get gadolinium medicines can develop a condition with severe thickening of the skin, muscles and other organs in the body (nephrogenic systemic fibrosis). Your healthcare provider should screen you to see how well your kidneys are working before you receive Gadoterate Meglumine Injection. Do not receive Gadoterate Meglumine Injection if you have had a severe allergic reaction to Gadoterate Meglumine Injection.
Before receiving Gadoterate Meglumine Injection, tell your healthcare provider about all your medical conditions, including if you: have had any MRI procedures in the past where you received a GBCA. Your healthcare provider may ask you for more information including the dates of these MRI procedures. are pregnant or plan to become pregnant. It is not known if Gadoterate Meglumine Injection can harm your unborn baby.
Talk to your healthcare provider about the possible risks to an unborn baby if a GBCA such as Gadoterate Meglumine Injection is received during pregnancy. have kidney problems, diabetes, or high blood pressure. have had an allergic reaction to dyes (contrast agents) including GBCAs. What are possible side effects of Gadoterate Meglumine Injection? See “What is the most important information I should know about Gadoterate Meglumine Injection?” Allergic reactions.
Gadoterate Meglumine Injection can cause allergic reactions that can sometimes be serious. Your healthcare provider will monitor you closely for symptoms of an allergic reaction. The most common side effects of Gadoterate Meglumine Injection include: nausea, headache, pain, or cold feeling at the injection site, and rash.
These are not all the possible side effects of Gadoterate Meglumine Injection. Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800…
