Follow all directions on your prescription label and read all medication guides or instruction sheets. Use the medicine exactly as directed.
Filgrastim is injected under the skin or as an infusion into a vein. A healthcare provider will give your first dose and may teach you how to properly use the medication by yourself.
Filgrastim vials and prefilled syringes do not contain the same concentrations of this medicine. Do not give an injection unless you are trained in properly measuring your dose from either the vial or the prefilled syringe.
Read and carefully follow any Instructions for Use provided with your medicine. Do not use filgrastim if you don't understand all instructions for proper use. Ask your doctor or pharmacist if you have questions.
Prepare your injection only when you are ready to give it. Do not use if the medicine has changed colors or has particles in it. Call your pharmacist for new medicine.
You may need frequent medical tests to help your doctor determine how long to treat you with filgrastim.
Store filgrastim in the original container in a refrigerator. Do not freeze and do not shake.
Take the medicine out of the refrigerator and allow it to reach room temperature for 30 minutes before injecting your dose. Do not leave the medicine at room temperature for longer than 24 hours.
Each single-use vial (bottle) or prefilled syringe is for one use only. Throw it away after one use, even if there is still medicine left inside.
Use a needle and syringe only once and then place them in a puncture-proof "sharps" container. Follow state or local laws about how to dispose of this container. Keep it out of the reach of children and pets.
