Filgrastim is an injection commonly used to increase neutrophils. It's a synthetic version of a naturally occurring substance called a colony-stimulating factor. Filgrastim works by stimulating the bone marrow to produce more white blood cells, specifically neutrophils, which are crucial for fighting infection. This injection is frequently used to prevent neutropenia, a condition characterized by low levels of neutrophils, often caused by cancer treatments like chemotherapy.
How Filgrastim Works:
Filgrastim, also known as Neupogen, is a granulocyte-colony stimulating factor (G-CSF). G-CSF stimulates the bone marrow to produce more neutrophils, thereby increasing their numbers in the blood. This helps the body fight infections more effectively, particularly important for individuals whose neutrophil counts have been suppressed by medications.
- Mechanism of Action: Stimulates bone marrow to increase neutrophil production.
- Administration: Given as an injection, either subcutaneously (under the skin) or intravenously (into a vein).
- Common Use: Prevention and treatment of neutropenia, often associated with cancer chemotherapy.
Other Considerations:
While Filgrastim is a common choice, other G-CSF medications exist. The choice of medication will depend on individual factors and the specific medical situation. Always consult with a healthcare professional for proper diagnosis and treatment.
Examples of other G-CSF medications:
- Pegfilgrastim (Neulasta) – a longer-acting version of Filgrastim.
- Other G-CSF brand names are available but may vary by country or region.
