Filgrastim is a common injection used to increase white blood cell (WBC) count. Several brand names exist, including Neupogen, Nivestym, Releuko, and Zarxio. This injection is frequently used to treat neutropenia, a condition characterized by low white blood cell counts, often caused by cancer treatments like chemotherapy.
How Filgrastim Works to Increase WBC Count
Filgrastim, a granulocyte-colony stimulating factor (G-CSF), stimulates the bone marrow to produce more white blood cells. This helps prevent infections that are more likely to occur when WBC counts are low. The injection can be administered intravenously (IV) or subcutaneously (under the skin). The treatment duration varies; for example, with filgrastim or lenograstim, a daily injection for up to 7 days may be prescribed.
Other Medications that Increase WBC Count
Besides Filgrastim, other medications, such as pegfilgrastim (Neulasta), also help increase white blood cell counts. Neulasta works similarly by stimulating the production of white blood cells, reducing the infection risk during chemotherapy. UDENYCA is another example of a prescription medicine that reduces infection chances due to low white blood cell counts in certain cancer patients.
Important Considerations
- Healthcare providers monitor blood counts during treatment with these medications.
- The specific medication and dosage depend on the individual's condition and treatment plan.
- Potential side effects vary and should be discussed with a doctor.
