What is Neupogen?Neupogen is a man-made form of granulocyte colony-stimulating factor (G-CSF), which is made using the bacteria E. coli. G-CSF is a substance naturally produced by the body. It stimulates the growth of neutrophils, a type of white blood cell important in the body's fight against infection.
Neupogen is used to treat neutropenia, a condition where the body makes too few neutrophils. Neutropenia may be a long-standing condition where your body does not make enough neutrophils, or it may be caused by drugs used to treat cancer.
What is the most important information I should know about Neupogen?Neupogen may reduce your chance of getting an infection, but does not prevent all infections. You can still get an infection during the short time when your neutrophil levels are low. Be alert for some of the common signs or symptoms of infection, such as fever, chills, rash, sore throat, diarrhea, or redness, swelling, or pain around a cut or sore. If you have any of these signs or symptoms during treatment with Neupogen, tell your doctor immediately.
If you have a sickle cell disorder, make sure that you tell your doctor before you start taking Neupogen. If you have a sickle cell crisis after getting Neupogen, tell your doctor right away.
If you are receiving Neupogen because you are also receiving chemotherapy, the last dose of Neupogen should be injected at least 24 hours before your next dose of chemotherapy.
You could have a reaction at an injection site. If there is a lump, swelling, or bruising at an injection site that does not go away, call your doctor.
Who should not take Neupogen?Do not take Neupogen if you are allergic to other medicines made using the bacteria E. coli.
What should I tell my doctor before I take the first dose of Neupogen?Tell your doctor about all prescription, over-the-counter, and herbal medications you are taking before beginning treatment with Neupogen. Also, talk to your doctor about your complete medical history, especially if you have sickle cell disorder, a blood cell disorder, chronic myeloid leukemia, myelodysplasia (also called "preleukemia"), or if you are receiving chemotherapy or radiation treatment.
