What is Filgrastim Duncan?
Filgrastim Duncan injection is used to treat neutropenia (low white blood cells) that is caused by cancer medicines. It is a synthetic (man-made) form of a substance that is naturally produced in your body called a colony stimulating factor. Filgrastim Duncan helps the bone marrow to make new white blood cells.
When certain cancer medicines are used to fight cancer cells, they also affect the white blood cells that fight infections. Filgrastim Duncan is used to prevent or reduce the risk of infection while you are being treated with cancer medicines. Filgrastim Duncan is also used to help the bone marrow recover after a bone marrow transplantation, for a process called peripheral blood progenitor cell collection in cancer patients, and to improve survival in cancer patients who have been exposed to radiation.
Filgrastim Duncan is available only with your doctor's prescription.
Filgrastim Duncan indications
Established Cytotoxic Chemotherapy: Filgrastim Duncan is indicated for reduction in the duration of neutropenia and the incidence of febrile neutropenia in patients treated with established cytotoxic chemotherapy for malignancy (with the exception of chronic myeloid leukemia and myelodysplastic syndromes) and for the reduction in the duration of neutropenia and its clinical sequelae in patients undergoing myeloablative therapy followed by bone marrow transplantation.
Peripheral Blood Progenitor Cell Mobilization (PBPC): Filgrastim Duncan is indicated for the mobilization of autologous peripheral blood progenitor cells alone, or following myelosuppressive chemotherapy in order to accelerate hematopoetic recovery by infusion of such cells, after myelosuppressive or myeloablative therapy. The safety and efficacy of Filgrastim Duncan are similar in adults and children receiving cytotoxic chemotherapy. Filgrastim Duncan is indicated for the mobilization of peripheral blood progenitor cells in normal volunteers for use in allogeneic peripheral blood progenitor cell transplantation.
Severe Chronic Neutropenia (SCN): In patients, children or adults, with severe congenital, cyclic or idiopathic neutropenia with an ANC of ≤0.5x109/L, and a history of severe or recurrent infections, long-term administration of Filgrastim Duncan is indicated to increase neutrophil counts and to reduce the incidence and duration of infection-related events.
HIV Infection: Filgrastim Duncan is indicated for the treatment of persistent neutropenia (ANC ≤1.0 x 109/L) in patients with advanced HIV infection, in order to reduce risk of bacterial infections, when other options to manage neutropenia are inappropriate.
Patients with Acute Myeloid Leukemia (AML): Filgrastim Duncan is indicated to reduce the duration of neutropenia and related clinical sequelae in patients undergoing induction or consolidation chemotherapy.

Filgrastim Duncan interactions

What other drugs will affect Filgrastim Duncan?
The safety and efficacy of Filgrastim Duncan given on the same day as myelosuppressive cytotoxic chemotherapy have not been definitively established. In view of the sensitivity of rapidly dividing myeloid cells to myelosuppressive cytotoxic chemotherapy, the use of Filgrastim Duncan is not recommended in the period from 24 hrs before to 24 hrs after chemotherapy. Preliminary evidence from a small number of patients treated concomitantly with Filgrastim Duncan and 5-fluorouracil indicate that the severity of neutropenia may be exacerbated. Possible interactions with other haematopoietic growth factors and cytokines have not yet been investigated in clinical trials.
Since lithium promotes the release of neutrophils, lithium is likely to potentiate the effect of Filgrastim Duncan. Although this interaction has not been formally investigated, there is no evidence that such an interaction is harmful.
Increased haematopoietic activity of the bone marrow in response to growth factor therapy has been associated with transient positive bone-imaging changes. This should be considered when interpreting bone-imaging results.
Incompatibilities: Filgrastim Duncan should not be diluted with saline solutions. If required, Filgrastim Duncan may be diluted in 5% glucose.
Diluted Filgrastim Duncan may be adsorbed to glass and plastic materials. However, when diluted in 5% glucose solution, Filgrastim Duncan is compatible with glass and a variety of plastic including PVC, polyolefin (a copolymer of polypropylene and polyethylene) and polypropylene.
Filgrastim Duncan side effects
See also:
What are the possible side effects of Filgrastim Duncan?
Filgrastim Duncan usually does not cause serious or life-threatening adverse effects and it only rarely has required discontinuance. Because most patients who receive Filgrastim Duncan have recently undergone cytotoxic chemotherapy, many of the adverse effects reported with Filgrastim Duncan therapy may actually result from the actions of the previously administered antineoplastic agents.
The most frequent adverse effect reported during Filgrastim Duncan therapy is deep, throbbing medullary bone pain, most often in the lower back, pelvis, ribs or sternum (eg, sites containing bone marrow). Sternal pain can imitate the pain of an acute myocardial infarction. The severity of the pain usually is increased in patients with more extensive leukocytosis. Non-opiate analgesics can alleviate this effect, and bone pain may spontaneously resolve with continued therapy.
Dose- or route-dependent, Filgrastim Duncan-induced leukocytosis (leukocyte count >100,000/mm3) can occur during therapy, and the drug should be discontinued if the absolute neutrophil count (ANC) rises >10,000/mm3 after the nadir is achieved. An ANC >10,000/mm3 will not increase the effectiveness of the drug, but can increase its toxicity.
Splenomegaly has been observed in both children and adults during therapy with Filgrastim Duncan, but is not common.

What is the most important information I should know about Filgrastim Duncan?
You should not use this medication if you are allergic to Filgrastim Duncan or to other medicines that contain the E. coli bacteria.
Before using Filgrastim Duncan, tell your doctor if you have a blood cell disorder (such as sickle cell anemia), chronic myeloid leukemia, myelodysplasia (also called "preleukemia"), or if you are receiving chemotherapy or radiation treatment.
Do not self-inject this medicine if you do not fully understand how to give the injection and properly dispose of used needles, syringes, IV tubing, and other items used to inject the medicine.
To be sure this medication is helping your condition, your blood may need to be tested often. This will help your doctor determine how long to treat you with Filgrastim Duncan. Your liver function will also need to be tested, and you may need bone density scans. Visit your doctor regularly.
Stop using Filgrastim Duncan and call your doctor at once if you have a serious side effect such as sudden or severe pain in your left upper stomach spreading up to your shoulder, rapid breathing or feeling short of breath, or signs of infection (fever, chills, sore throat, flu symptoms, easy bruising or bleeding, loss of appetite, nausea and vomiting, mouth sores, or unusual weakness).
