OptiMARK 0.5 mmol/mL (gadoversetamide) Injection is a paramagnetic agent used with magnetic resonance imaging (MRI) in patients with abnormal blood-brain barrier or abnormal vascularity of the brain, spine and associated tissues, and to provide contrast enhancement and facilitate visualization of lesions with abnormal vascularity in the liver in patients who are highly suspect for liver structural abnormalities on computed tomography. Common side effects include headache, widening of blood vessels, changes in taste, dizziness, nausea, and tingling sensation.
OptiMARK Injection is administered as a bolus peripheral intravenous injection at a dose of 0.2 mL/kg (0.1 mmol/kg) and at a rate of 1 to 2 mL/sec delivered by manual or by power injection.

Optimark FDA Prescribing Information: Side Effects
A total of 1309 subjects (24 healthy volunteers and 1285 patients) received OptiMARK™ Injection and 46 subjects received placebo (saline). Of the 1309 subjects who received OptiMARK™ Injection, 680 (52%) were men and 629 (48%) were women with a mean age of 50 years (range 12 to 85 years). In this population there were 1102 (84%) white, 116 (9%) black, 33 (3%) Asian, and 58 (4%) subjects and patients of other racial groups.
In the clinical trials there were 8 serious adverse events and 1 death. The one death occurred in a patient with advanced multisystem disease and appeared to be related to the underlying disease. Six of the eight serious events appeared to be related to underlying disease. Two patients had either persistent paresthesia or numbness of unknown etiology that required hospitalization for diagnostic evaluations or treatment.
Of the 1309 subjects, 460 (35%) reported at least one adverse event out of a total of 997 adverse events; and 22 (47.8%) of the 46 subjects who received placebo reported at least one adverse event out of a total of 81 adverse events.
The most commonly noted adverse events were headache (9.4%), vasodilatation (6.4%), taste perversion (6.2%), dizziness (3.7%), nausea (3.2%), and paresthesia (2.2%). All adverse events reported in 1% or greater of all patients are listed in Table 5. Of the subjects and patients who experienced adverse events, 95.8% of the adverse events were of mild or moderate intensity after dosing with OptiMARK™ Injection.
