Preparation: Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration. Using aseptic techniques, attach a sterile needle to a sterile syringe. Remove the flip off from the vial containing FILGRASTIM (LEUCOGEN), and wipe the rubber stopper with a disinfectant. Insert the needle into the vial, and withdraw into the syringe an appropriate volume of solution If required, FILGRASTIM (LEUCOGEN) may be diluted in 5% dextrose. FILGRASTIM (LEUCOGEN) diluted to concentrations between 5 and 15 mcg/ml should be protected from adsorption to plastic materials by the addition of Albumin (Human) to a final concentration of 2 mg/ml. When diluted in 5% dextrose or 5% dextrose plus Albumin (Human), FILGRASTIM (LEUCOGEN) is compatible with glass and plastic bottles and materials. Dilution of FILGRASTIM (LEUCOGEN) to a final concentration of less than 5 mcg/ml is not recommended at any time.
