Why is this medication prescribed?

Granix (tbo-filgrastim) is prescribed primarily to help prevent infections in patients who are undergoing chemotherapy treatments for cancer. Chemotherapy can often suppress the bone marrow’s ability to produce enough white blood cells, particularly neutrophils, which are essential for fighting infections. Granix belongs to a class of drugs known as colony-stimulating factors (CSFs) or hematopoietic growth factors.

Granix works by stimulating the production of white blood cells, specifically neutrophils, in the bone marrow. By increasing the number of neutrophils, Granix helps reduce the risk of infections, particularly febrile neutropenia, which is a significant concern in cancer patients undergoing chemotherapy. Febrile neutropenia refers to a fever combined with a low white blood cell count, which can leave patients vulnerable to serious infections.

In summary, Granix is prescribed to support patients undergoing chemotherapy by boosting their immune system and reducing the risk of infections associated with low white blood cell counts. It plays a crucial role in helping cancer patients complete their chemotherapy treatment regimens effectively while minimizing the risk of potentially life-threatening infections.

How should this medicine be used?

Granix (tbo-filgrastim) is typically used to help prevent infections in patients undergoing chemotherapy treatment for cancer. Here’s how it is generally used:

• Administration: Granix is administered as an injection under the skin (subcutaneously). Healthcare professionals usually perform the injection in a clinical setting, such as a hospital or clinic. Patients should not attempt to self-administer Granix unless specifically instructed by their healthcare provider.
• Dosage: The dosage of Granix can vary depending on factors such as the patient’s body weight, the specific chemotherapy regimen being used, and the individual patient’s response to treatment. The healthcare provider will determine the appropriate dosage for each patient.
• Frequency: The frequency of Granix injections can also vary. It is typically administered once per chemotherapy cycle, with the first injection given approximately 24 hours after chemotherapy. However, the specific schedule may be adjusted based on individual patient needs and treatment protocols.
• Duration: Granix is usually given for the duration of the chemotherapy treatment cycle. The healthcare provider will determine how many cycles of chemotherapy and Granix injections are necessary based on the patient’s condition and treatment plan.
• Proper Handling: Patients should store Granix as directed by the healthcare provider, typically in the refrigerator. Before administration, the medication should be allowed to come to room temperature to reduce discomfort during injection. Patients should not shake the vial or syringe containing Granix vigorously.
