Drug Handling

  • Visually inspect Optimark for particulate matter and discoloration prior to administration. Do not use the solution if it is discolored or particulate matter is present.
  • Do not mix Optimark with other medications or parenteral nutrition and do not administer Optimark in the same intravenous line as other medications because of the potential for chemical incompatibility.

Imaging

  • Complete the imaging procedure within 1 hour of the injection of Optimark.
  • Paramagnetic contrast agents may impair the visualization of lesions seen on non-contrast MRI. Interpret Optimark MR images with companion non-contrast MR images.
