Best Choice of Syringes for You

GCSF can be supplied either as a single dose vial or as a pre-filled syringe. For small doses, patients generally draw up the medication from a vial. For larger doses, patients may give all or part of the medication in a pre-filled syringe. Your provider will discuss the best option for you. Your nurse or pharmacist will instruct you on how to accurately prepare your dose and teach you how to administer a subcutaneous injection. Contact us if you have questions or would like additional advice on how to draw up and administer GCSF.


For small doses of GCSF your provider may prescribe an insulin syringe. Insulin syringes have orange caps. Insulin syringes measure in units rather than milliliters (mL). A U-100 insulin syringe has 100 units per 1 mL, so each 1 unit = 0.01 mL. Insulin syringes often have finer and shorter needles than other syringes. Shorter needles are often easier to use and have less discomfort than longer needles.

Here are comparisons of syringes, which measure in mL to insulin syringes, which measure in units.
