Why is this medication prescribed?

Filgrastim injection products (Granix, Neupogen, Nivestym, Releuko, Zarxio) are used to lower the risk of infection in patients with non-myeloid cancer (cancer that does not involve the bone marrow) who are receiving chemotherapy drugs that may lower the number of neutrophils (a type of blood cell needed to fight infection). Acute myeloid leukemia (AML), a form of white blood cell cancer, is treated with chemotherapy drugs. Filgrastim injection products (Neupogen, Nivestym, Releuko, Zarxio) are used to help increase the number of white blood cells and shorten the duration of fever in patients receiving these treatments. Injections of filgrastim (Neupogen, Nivestym, Releuko, Zarxio) are also used to treat severe chronic neutropenia (a disease in which there are not enough neutrophils in the blood) and to treat bone marrow transplant recipients. Injections of filgrastim (Neupogen, Nivestym, and Zarxio) are also used to prepare blood for leukapheresis, a procedure that involves the removal of certain blood cells from the body. Injections of filgrastim (Neupogen) are additionally used to improve survival rates in patients who have been exposed to hazardous levels of radiation, which can seriously and potentially fatally damage your bone marrow. The drug filgrastim belongs to the group of drugs known as colony-stimulating factors. It functions by enhancing the body’s production of neutrophils.

How should this medicine be used?

Injections of filgrastim are available as liquid solutions in vials and prefilled syringes for subcutaneous (under the skin) or intravenously (into a vein) administration. When used to treat severe chronic neutropenia, filgrastim injection products (Neupogen, Nivestym, Releuko, Zarxio) may be administered twice daily. Your ailment and how well your body responds to the medication will determine how long you need to receive treatment.

You will receive your first dose of the medication at least 24 hours after receiving a dose of chemotherapy, and you will continue to receive the medication every day for up to 2 weeks or until your blood cell counts return to normal, whichever comes first, if you are using filgrastim injection products to reduce your risk of infection, shorten the duration of your fever, or increase the number of white blood cells while receiving chemotherapy. You will receive the drug at least 24 hours after receiving chemotherapy and at least 24 hours after the bone marrow is infused if you are taking filgrastim injectable products to reduce the risk of infection after a bone marrow transplant. You will receive your first dose of the medicine at least 4 days before to the first leukapheresis if you are using filgrastim injection products to prepare your blood for leukapheresis. You will continue to receive the medication until the last leukapheresis. You could need to utilize filgrastim injection products for a long time if you’re treating severe persistent neutropenia with them. Your doctor will closely monitor you if you are receiving filgrastim injection because you were exposed to dangerous levels of radiation, and the length of your therapy will depend on how well your body responds to the drug. Stop using filgrastim injection products only after seeing your physician.

You might be given filgrastim injection products by a nurse or other medical professional, or you might be instructed to administer the medication yourself at home. A healthcare professional will demonstrate how to inject the drug if you or a caregiver will be injecting filgrastim injection products at home. Make sure you comprehend these instructions. If you have any questions, ask your healthcare practitioner. As instructed, use filgrastim injection products. Use it only as directed by your doctor, neither more nor less often.

Syringes or vials containing filgrastim solution shouldn’t be shaken. Before injecting, always have a look at the filgrastim injection goods. If the product has beyond its expiration date, contains particles, or seems foamy, foggy, or discolored, do not use it.

Only use one vial or syringe per object. Do not re-use the syringe or vial, even if there is still some solution inside. Put used needles, syringes, and vials in a container that won’t puncture. How to get rid of the puncture-resistant container should be discussed with your doctor or pharmacist.

You might begin with filgrastim injection products at a low dose, then your doctor may gradually raise it. Depending on how your body responds to the drug, your doctor may decide to lower your dose.

You should be aware that utilizing filgrastim injection products to treat severe persistent neutropenia won’t cure your disease; instead, it will only regulate it. Even if you feel well, keep using filgrastim injection products. Without consulting your doctor, do not stop using filgrastim injection products.

For a copy of the manufacturer’s information for the patient, ask your pharmacist or doctor.

Other uses for this medicine

Aplastic anemia (a condition in which the bone marrow does not produce enough healthy blood cells) and certain types of myelodysplastic syndrome (a group of conditions in which the bone marrow produces blood cells that are misshapen and does not produce enough healthy blood cells) are other conditions that may occasionally be treated with filgrastim injection products. Additionally, human immunodeficiency virus (HIV) positive patients and patients taking certain medications that reduce neutrophil counts may occasionally use filgrastim injection products to lessen their risk of infection. When using this medication to treat your condition, discuss the risks with your doctor.
