Why is this medication prescribed?

Filgrastim Injection is a medication prescribed for several purposes, primarily to stimulate the production of white blood cells in the body. It is commonly used in the following situations:

  • Chemotherapy Treatment: Filgrastim can be prescribed to cancer patients undergoing chemotherapy, as chemotherapy often suppresses the production of white blood cells, leaving the patient vulnerable to infections. By boosting white blood cell production, Filgrastim helps reduce the risk of infections.
  • Bone Marrow Transplant: Patients who have undergone bone marrow transplantation may also receive Filgrastim to help stimulate the production of new white blood cells.
  • Severe Chronic Neutropenia: This is a condition where the body produces an abnormally low number of neutrophils, which are crucial for fighting infections. Filgrastim can be prescribed to treat severe chronic neutropenia.
  • Peripheral Blood Progenitor Cell Collection: Filgrastim may also be used to mobilize stem cells from the bone marrow into the bloodstream for collection in preparation for a stem cell transplant.
  • Other Conditions: Filgrastim might also be used in other situations where there is a need to increase white blood cell counts, such as certain types of infections or following severe trauma.

How should this medicine be used?

Filgrastim Injection is typically administered as a subcutaneous injection, meaning it is injected under the skin. Here’s a general guide on how it is typically used:

  • Preparation: Wash your hands thoroughly with soap and water before handling the medication. Gather all the necessary supplies, including the vial of Filgrastim, a syringe, and alcohol swabs. Check the expiration date and the appearance of the medication before use. If there are any abnormalities or if the medication has expired, do not use it and consult your healthcare provider.
  • Administration: Choose an injection site, typically the abdomen or thigh, and clean the area with an alcohol swab. Allow the skin to air dry before proceeding.
  • Withdrawal of Medication: If instructed by your healthcare provider, withdraw the prescribed amount of Filgrastim solution into the syringe. Make sure to follow the precise dosage instructions provided to you.
  • Injection: Pinch the skin around the cleaned area to create a fold. Insert the needle at a 45 to 90-degree angle into the fold of skin. Inject the medication slowly and steadily.
  • Disposal: After injecting the medication, remove the needle from the skin and dispose of it properly in a puncture-resistant container. Do not recap the needle. Dispose of any unused medication as per your healthcare provider’s instructions or local guidelines.
  • Post-Injection Care: Apply gentle pressure to the injection site with a clean cotton ball or gauze pad. Do not rub the area. If there is any bleeding, apply a bandage if necessary. Wash your hands again after handling the used materials.

It’s important to follow your healthcare provider’s instructions carefully regarding the dosage and administration of Filgrastim Injection. They will provide specific guidance tailored to your condition and individual needs. Additionally, healthcare providers or nurses often provide instructions on how to administer the injection correctly. If you have any questions or concerns about using Filgrastim Injection, it’s crucial to consult your healthcare provider for clarification and guidance.

Other uses for this medicine

Other uses for Filgrastim Injection include:

  • Stem Cell Mobilization: Filgrastim can be used to help mobilize stem cells from the bone marrow into the bloodstream for collection in patients undergoing stem cell transplantation.
  • Neutropenia Prevention: It may be used to prevent neutropenia (low white blood cell count) in patients undergoing bone marrow transplant or those with certain other medical conditions that affect the immune system.

What special precautions should I follow?

As for special precautions to follow when using Filgrastim Injection, here are some important considerations:

  • Allergic Reactions: If you have a history of allergic reactions to Filgrastim or any other medications, inform your healthcare provider before starting treatment.
  • Bone Pain: Filgrastim can sometimes cause bone pain, especially in the sternum (breastbone), pelvis, and lower back. Inform your healthcare provider if you experience severe or persistent bone pain.
  • Monitoring: Your healthcare provider may regularly monitor your blood cell counts while you are receiving Filgrastim treatment to adjust the dosage as needed and monitor for any potential side effects.
  • Storage: Follow the storage instructions provided by your healthcare provider or pharmacist. Store Filgrastim Injection in the refrigerator and protect it from light. Do not freeze the medication.
  • Pregnancy and Breastfeeding: Inform your healthcare provider if you are pregnant, planning to become pregnant, or breastfeeding before starting Filgrastim treatment. The potential risks and benefits should be discussed with your healthcare provider.

What side effects can this medication cause?

Filgrastim Injection, like any medication, can cause side effects. Not everyone will experience these side effects, and their severity can vary from person to person. Some common side effects of Filgrastim Injection include:

  • Bone Pain: This is one of the most commonly reported side effects. It often manifests as mild to moderate pain in the bones, particularly in the sternum (breastbone), pelvis, and lower back.
  • Injection Site Reactions: You may experience redness, swelling, or tenderness at the site of injection. These reactions are usually mild and temporary.
  • Headache: Some individuals may experience headaches while receiving Filgrastim treatment.
  • Nausea and Vomiting: These gastrointestinal symptoms are relatively common but are usually mild and transient.
  • Fever: Filgrastim treatment may cause a mild increase in body temperature, which typically resolves on its own.
  • Fatigue: Some individuals may experience fatigue or tiredness during Filgrastim treatment.
  • Allergic Reactions: Although rare, some people may experience allergic reactions to Filgrastim, which can include hives, itching, difficulty breathing, or swelling of the face, lips, tongue, or throat. Seek medical attention immediately if you experience any signs of an allergic reaction.
  • Splenomegaly (Enlargement of the Spleen): In rare cases, Filgrastim treatment may lead to enlargement of the spleen, which can cause abdominal pain, fullness, or discomfort.
  • Capillary Leak Syndrome: This is a rare but potentially serious side effect characterized by fluid leakage from blood vessels into surrounding tissues, leading to swelling, low blood pressure, and potentially organ damage.

It’s essential to report any side effects or symptoms you experience while receiving Filgrastim Injection to your healthcare provider promptly.
