What is Filastin?
Filastin 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. Filastin 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. Filastin is used to prevent or reduce the risk of infection while you are being treated with cancer medicines. Filastin 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.
Filastin is available only with your doctor's prescription.
Filastin indications
Established Cytotoxic Chemotherapy: Filastin 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): Filastin 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 Filastin are similar in adults and children receiving cytotoxic chemotherapy. Filastin 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 Filastin is indicated to increase neutrophil counts and to reduce the incidence and duration of infection-related events.
HIV Infection: Filastin 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): Filastin is indicated to reduce the duration of neutropenia and related clinical sequelae in patients undergoing induction or consolidation chemotherapy.
How should I use Filastin?
Use Filastin as directed by your doctor. Check the label on the medicine for exact dosing instructions.
- An extra patient leaflet is available with Filastin. Talk to your pharmacist if you have questions about this information.
- Do not shake Filastin. Shaking may damage Filastin. If the vial or syringe has been shaken, the solution may appear foamy and should not be used.
- Filastin is usually given as an injection at your doctor's office, hospital, or clinic. If you will be using Filastin at home, a health care provider will teach you how to use it. Be sure you understand how to use Filastin. Follow the procedures you are taught when you use a dose. Contact your health care provider if you have any questions.
- Do not use Filastin if it contains particles, is cloudy or discolored, or if the vial or syringe is cracked or damaged.
- Use only disposable syringes and needles. Use the syringes and needles only once and dispose of them in a puncture-proof container as instructed by your health care provider.
- Choose a new site each time you inject Filastin. Do not inject into an area that is tender, red, bruised, hard, swollen, or has scars or stretch marks.
- Discard any unused portion of medicine left in the vial or syringe.
- Continue to use Filastin for the full course of treatment. Do not miss any doses.
- Filastin works best if it is used at the same time each day.
- If you use Filastin because you also receive chemotherapy, the last dose of Filastin should be used at least 24 hours before your next dose of chemotherapy.
- Keep this product, as well as syringes and needles, out of the reach of children and away from pets. Do not reuse needles, syringes, or other materials. Ask your health care provider how to dispose of these materials after use. Follow all local rules for disposal.
- If you miss a dose of Filastin, contact your doctor right away.
Ask your health care provider any questions you may have about how to use Filastin.

Filastin interactions

What other drugs will affect Filastin?
The safety and efficacy of Filastin 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 Filastin 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 Filastin 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 Filastin. 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: Filastin should not be diluted with saline solutions. If required, Filastin may be diluted in 5% glucose.
Diluted Filastin may be adsorbed to glass and plastic materials. However, when diluted in 5% glucose solution, Filastin is compatible with glass and a variety of plastic including PVC, polyolefin (a copolymer of polypropylene and polyethylene) and polypropylene.
Filastin side effects
See also:
What are the possible side effects of Filastin?
Filastin usually does not cause serious or life-threatening adverse effects and it only rarely has required discontinuance. Because most patients who receive Filastin have recently undergone cytotoxic chemotherapy, many of the adverse effects reported with Filastin therapy may actually result from the actions of the previously administered antineoplastic agents.
The most frequent adverse effect reported during Filastin 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, Filastin-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 Filastin, but is not common.
Filastin contraindications

What is the most important information I should know about Filastin?
You should not use this medication if you are allergic to Filastin or to other medicines that contain the E. coli bacteria.
Before using Filastin, 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 Filastin. Your liver function will also need to be tested, and you may need bone density scans. Visit your doctor regularly.
Stop using Filastin 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).
