What syringes and needles should I use for administration?
Use a 1 mL syringe. Low dead-volume
syringes and/or needles should be used. If standard syringes and needles are used, there may not be sufficient volume to extract a sixth dose from a single vial. If a low dead-volume syringe is not available a standard 1 mL syringe may be used. Please see the Dosing & Administration
