DOTAREM
DOTAREM- gadoterate meglumine injection
Guerbet LLC
WARNING: NEPHROGENIC SYSTEMIC FIBROSIS (NSF)
Gadolinium-based contrast agents (GBCAs) increase the risk for NSF among patients with impaired elimination of the drugs. Avoid use of GBCAs 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 DOTAREM 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 ( 5.1)] .
1 INDICATIONS AND USAGE
DOTAREM 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.
2 DOSAGE AND ADMINISTRATION
2.1 Dosing Guidelines
For adult and pediatric patients (including term neonates), the recommended dose of DOTAREM is 0.2 mL/kg (0.1 mmol/kg) body weight administered as an intravenous bolus injection, manually or by power injector, at a flow rate of approximately 2 mL/second for adults and 1 — 2 mL/second for pediatric patients. Table 1 provides weight-adjusted dose volumes.

To ensure complete injection of DOTAREM the injection may be followed by normal saline flush. Contrast MRI can begin immediately following DOTAREM injection.
2.2 Drug Handling
- Visually inspect DOTAREM for particulate matter prior to administration. Do not use the solution if particulate matter is present or if the container appears damaged. DOTAREM should be a clear, colorless to yellow solution.
- Do not mix with other drugs or parenteral nutrition.
- Discard any unused portions of the drug.
Directions for Use of the DOTAREM (gadoterate meglumine) Injection
Glass vial:
Aseptically draw up the contrast medium into a disposable syringe and use immediately.
Glass or plastic pre-filled syringe:
1) Holding the syringe barrel firmly, screw the threaded tip of the plunger rod clockwise into the cartridge plunger.
- For glass pre-filled syringe: Push forward a few millimeters to break any friction between the cartridge plunger and syringe barrel.
- For plastic pre-filled syringe: After screwing the push rod into the syringe cartridge plunger, turn the push rod clockwise an additional ½ turn so that the cartridge plunger rotates freely.
2) Holding the syringe vertically so the rubber cap is pointed upward, aseptically remove the rubber cap from the tip of the syringe and attach either a sterile, disposable needle or compatible needleless luer lock tubing set using a push-twist action. At this point, the tubing set is not attached to a patient’s intravenous connection.
- If using a needleless luer lock tubing set, check the connection between the syringe and the tubing as the fluid flows. Ensure that the connection is successful before administration of DOTAREM Injection.
- If using a needle, hold the syringe vertically and push plunger forward until all of the air is evacuated and fluid either appears at the tip of the needle or the tubing is filled. Following the usual venous blood aspiration procedure, complete the DOTAREM injection.
3) To ensure complete delivery of the contrast medium, the injection may be followed by a normal saline flush.
4) Properly dispose of the syringe and any other materials used.
