Why is this medication prescribed?

Pegfilgrastim injection is prescribed to help prevent or reduce the severity of certain side effects associated with cancer treatments, specifically chemotherapy. It is a synthetic form of a natural protein called granulocyte-colony stimulating factor (G-CSF).

Chemotherapy, while effective in killing cancer cells, can also affect the bone marrow, where new blood cells are produced. This can lead to a decrease in the number of neutrophils, which are a type of white blood cell important for fighting infections. When the neutrophil count drops significantly, it can increase the risk of developing febrile neutropenia, a condition characterized by a fever and a low white blood cell count. This condition can be dangerous and potentially life-threatening as it leaves the body vulnerable to infections.

Pegfilgrastim works by stimulating the bone marrow to produce more neutrophils, thus reducing the duration and severity of neutropenia and lowering the risk of febrile neutropenia during chemotherapy treatment. It is administered as a single injection once per chemotherapy cycle, as opposed to daily injections of the shorter-acting form of G-CSF.

How should this medicine be used?

Pegfilgrastim injection should be used exactly as prescribed by a healthcare professional, typically an oncologist or a nurse specializing in cancer care. It is important to follow their instructions carefully. Here are some general guidelines for using Pegfilgrastim:

• Administration: Pegfilgrastim is usually given as a subcutaneous injection, which means it is injected just under the skin. It is commonly administered in the fatty tissue of the upper arm, abdomen, or thigh. The injection site may vary, so always follow the specific instructions given by your healthcare provider.
• Timing: Pegfilgrastim is typically given on the same day as your chemotherapy treatment. It is important to administer it at the appropriate time as directed by your healthcare provider to get the best results in stimulating the bone marrow and supporting your immune system.
• Single Dose: Unlike other forms of G-CSF that require daily injections, Pegfilgrastim is a long-acting formulation. It is usually given as a single injection per chemotherapy cycle. This convenience reduces the frequency of injections, making it more patient-friendly.
• Do Not Shake: Pegfilgrastim comes in a prefilled syringe, and it’s essential not to shake the syringe. Gently inspect the solution for any particles or discoloration before administering the injection. If you notice anything unusual, do not use it and consult your healthcare provider.
• Needle Disposal: After administering the injection, dispose of the syringe and needle properly according to medical waste disposal guidelines or as directed by your healthcare provider.
• Medical Supervision: Pegfilgrastim should always be administered by a healthcare professional. If you are using it at home, make sure you have been properly trained on how to do it safely and correctly.
• Missed Dose: If you miss a scheduled dose of Pegfilgrastim, contact your healthcare provider immediately for advice on what to do next.

Remember, always communicate with your healthcare team about any concerns or questions you have regarding the use of Pegfilgrastim. They are there to help you manage your treatment and ensure your well-being throughout your cancer journey.

Other uses for this medicine
