Important warnings This medicine can cause some serious health issues

Intravenous route (solution)

Gadodiamide is not for intrathecal use.

Inadvertent intrathecal use has caused convulsions, coma, and sensory and motor neurologic deficits.

Gadolinium-based contrast agents (GBCAs) increase the risk for nephrogenic systemic fibrosis (NSF) among patients with impaired elimination of the drugs Avoid use of GBCAs unless the diagnostic information is essential and not available with non-contrast enhanced MRI.

NSF may result in fatal or debilitating systemic fibrosis affecting the skin, muscle, and internal organs.

Do not administer to patients with chronic, severe kidney disease (GFR less than 30 mL/min/1.73 m(2)) or acute kidney injury.

Screen all patients for acute kidney injury and other conditions that may reduce renal function.

For patients at risk for chronically reduced renal function (eg, age greater than 60 years, hypertension, or diabetes), perform lab testing to estimate the GFR.

For patients with the highest NSF risk, do not exceed recommended dose and allow a sufficient time period for elimination prior to readministration.
