MAGNEVIST®
(gadopentetate dimeglumine) Injection

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.

  • Do not administer MAGNEVIST (gadopentetate dimeglumine) to patients with:
    • chronic, severe kidney disease (GFR < 30 mL/min/1.73m²), or
    • acute kidney injury (see CONTRAINDICATIONS).
  • Screen patients for acute kidney injury and other conditions that may reduce renal function. For patients at risk for chronically reduced renal function (for example, age > 60 years, hypertension or diabetes), estimate the glomerular filtration rate (GFR) through laboratory testing.

Do not exceed the recommended MAGNEVIST (gadopentetate dimeglumine) 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).
