What is Neulasta?
Neulasta (pegfilgrastim) is a man-made form of a protein that stimulates the growth of white blood cells in your body. White blood cells help your body fight against infection.
Neulasta injection is used to prevent neutropenia, a lack of certain white blood cells caused by receiving chemotherapy.
Neulasta may also be used for purposes not listed in this medication guide.
Before using Neulasta, tell your doctor if you have sickle cell disorder, chronic myeloid leukemia, myelodysplasia (also called "preleukemia"), or if you are allergic to latex.
Follow all directions on your medicine label and package. Tell each of your healthcare providers about all your medical conditions, allergies, and all medicines you use.
Do not self-inject Neulasta if you do not fully understand how to give the injection and properly dispose of used needles and syringes.
Neulasta is usually given once per chemotherapy cycle. It should not be given within 14 days before or 24 hours after you receive chemotherapy.

It is not known whether pegfilgrastim will harm an unborn baby. Tell your doctor if you are pregnant or plan to become pregnant.
If you are pregnant, your name may be listed on a pregnancy registry. This is to track the outcome of the pregnancy and to evaluate any effects of Neulasta on the baby.

How should I use Neulasta?
Neulasta is injected under the skin. You may be shown how to use injections at home. Do not self-inject this medicine if you do not fully understand how to give the injection and properly dispose of used needles and syringes.
Read all patient information, medication guides, and instruction sheets provided to you. Ask your doctor or pharmacist if you have any questions.
Neulasta is usually given once per chemotherapy cycle. This medication should not be given within 14 days before or 24 hours after you receive chemotherapy.
Do not shake the prefilled syringe. Prepare your dose only when you are ready to give an injection. Do not use if the medicine has changed colors or has particles in it. Call your pharmacist for new medicine.
The Neulasta On-body Injector is a special device placed on the skin that delivers your pegfilgrastim dose at a specific time. Read and carefully follow all instructions for using this product. You will need to wear the device for 27 hours before the dose begins. The timed dose will then be released from the device slowly over a 45-minute period. While wearing the On-body Injector, you or a caregiver will need to check the device to make sure it is working properly.
Each prefilled Neulasta syringe or On-body Injector is for one use only. Throw away after one use, even if there is still some medicine left in it after injecting your dose.
Use a disposable needle and syringe only once. Follow any state or local laws about throwing away used needles and syringes. Use a puncture-proof "sharps" disposal container (ask your pharmacist where to get one and how to throw it away). Keep this container out of the reach of children and pets.
You may need frequent medical tests to help your doctor determine how long to treat you with this medicine.
Store Neulasta in the refrigerator, do not freeze. Protect from light and do not shake.
Take the medicine out of the refrigerator and allow it to reach room temperature before injecting your dose. Do not leave the medicine at room temperature for longer than 48 hours.
