Preparation and Administration
VIVIMUSTA is a hazardous drug. Follow applicable special handling and disposal procedures.1
VIVIMUSTA is a clear and colorless to yellow solution in a multiple-dose vial.
Store VIVIMUSTA refrigerated at 2°C to 8°C (36°F to 46°F). When refrigerated, the contents may partially freeze. Allow the vial to reach room temperature (15°C to 30°C or 59°F to 86°F) prior to use. Observe the contents of the vial for any visible solid or particulate matter. Do not use the product if solid or particulate matter is observed after reaching room temperature.
Intravenous Infusion
Aseptically withdraw the volume needed for the required dose from the 25 mg/mL solution as per Table 1 below and immediately transfer to a 250 mL infusion bag of one of the following diluents: 0.9% Sodium Chloride Injection, USP; or 2.5% Dextrose/0.45% Sodium Chloride Injection, USP.
The resulting final concentration of bendamustine hydrochloride in the infusion bag should be within 0.1 mg/mL to 1.36 mg/mL.
After transferring, thoroughly mix the contents of the infusion bag. The admixture should be a clear and colorless to slightly yellow solution.
No other diluents have been shown to be compatible [see Dosage and Administration (2.4)].

Complete administration of diluted VIVIMUSTA within this period of time.
VIVIMUSTA (bendamustine hydrochloride injection) is supplied in a multiple-dose vial. Retain the partially used vial in original package to protect from light and store refrigerated (2°C to 8°C or 36°F to 46°F) if additional dose withdrawal from the same vial is intended.
