Stimufend

Generic name: pegfilgrastim-fpgk

What is Stimufend?

Stimufend is a man-made form of granulocyte colony-stimulating factor (G-CSF). G-CSF is a substance produced by the body. It stimulates the growth of neutrophils, a type of white blood cell important in the body's fight against infection.

Who should not use Stimufend?

Do not take Stimufend if you have had a serious allergic reaction to pegfilgrastim products or filgrastim products.

What should I tell my healthcare provider before using Stimufend?

Before you receive Stimufend, tell your healthcare provider about all of your medical conditions, including if you:

  • have a sickle cell disorder.
  • have kidney problems.
  • are allergic to latex. The needle cap on the prefilled syringe contains dry natural rubber (derived from latex). You should not give Stimufend using the prefilled syringe if you have latex allergies.
  • are pregnant or plan to become pregnant. It is not known if Stimufend will harm your unborn baby.
  • are breastfeeding or plan to breastfeed. It is not known if Stimufend passes into your breast milk.

Tell your healthcare provider about all of the medicines you take, including prescription and over-the-counter medicines, vitamins, and herbal supplements.

How should I use Stimufend?

  • Stimufend is given as an injection under your skin (subcutaneous injection) by a healthcare provider. If your healthcare provider decides that the subcutaneous injections can be given at home by you or your caregiver, follow the detailed “Instructions for use” that comes with your Stimufend for information on how to prepare and inject a dose of Stimufend.
  • You and your caregiver will be shown how to prepare and inject Stimufend before you use it.
  • You should not inject a dose of Stimufend to children weighing less than 45 kg from a Stimufend prefilled syringe. A dose less than 0.6 mL (6 mg) cannot be accurately measured using the Stimufend prefilled syringe.
  • If you are receiving Stimufend because you are also receiving chemotherapy, the last dose of Stimufend should be injected at least 14 days before and 24 hours after your dose of chemotherapy.
  • If you miss a dose of Stimufend, talk to your healthcare provider about when you should give your next dose.

What are the possible side effects of Stimufend?

Stimufend may cause serious side effects, including:

  • Spleen rupture. Your spleen may become enlarged and can rupture. A ruptured spleen can cause death. Call your healthcare provider right away if you have pain in the left upper stomach area or your left shoulder.
  • A serious lung problem called Acute Respiratory Distress Syndrome (ARDS). Call your healthcare provider or get emergency help right away if you have shortness of breath with or without a fever, trouble breathing, or a fast rate of breathing.
  • Serious allergic reactions. Stimufend can cause serious allergic reactions. These reactions can cause a rash over your whole body, shortness of breath, wheezing, dizziness, swelling around your mouth or eyes, fast heart rate, and sweating. If you have any of these symptoms, stop using Stimufend and call your healthcare provider or get emergency medical help right away.
  • Sickle cell crises. You may have a serious sickle cell crisis, which could lead to death, if you have a sickle cell disorder and receive Stimufend. Call your healthcare provider right away if you have symptoms of sickle cell crisis such as pain or difficulty breathing.
  • Kidney injury (glomerulonephritis). Stimufend can cause kidney injury. Call your healthcare provider right away if you develop any of the following symptoms:
    • swelling of your face or ankles
    • blood in your urine or dark colored urine
    • you urinate less than usual
  • Increased white blood cell count (leukocytosis). Your healthcare provider will check your blood during treatment with Stimufend.
  • Decreased platelet count (thrombocytopenia). Your healthcare provider will check your blood during treatment with Stimufend. Tell your healthcare provider if you have unusual bleeding or bruising during treatment with Stimufend. This could be a sign of decreased platelet counts, which may reduce the ability of your blood to clot.
  • Capillary Leak Syndrome. Stimufend can cause fluid to leak from blood vessels into your body's tissues. This condition is called “Capillary Leak Syndrome” (CLS). CLS can quickly cause you to have symptoms that may become life-threatening. Get emergency medical help right away if you develop any of the following symptoms:
    • swelling or puffiness and are urinating less than usual
    • trouble breathing
    • swelling of your stomach area (abdomen) and feeling of fullness
    • dizziness or feeling faint
    • a general feeling of tiredness
  • Myelodysplastic syndrome and acute myeloid leukemia. If you have breast cancer or lung cancer, when Stimufend is used with chemotherapy and radiation therapy, or with radiation therapy alone, you may have an increased risk of developing a precancerous blood condition called myelodysplastic syndrome (MDS) or a blood cancer called acute myeloid leukemia (AML). Symptoms of MDS and AML may include tiredness, fever, and easy bruising or bleeding. Call your healthcare provider if you develop these symptoms during treatment with Stimufend.
  • Inflammation of the aorta (aortitis). Inflammation of the aorta (the large blood vessel which transports blood from the heart to the body) has been reported in patients who received pegfilgrastim products. Symptoms may include fever, abdominal pain, feeling tired, and back pain. Call your healthcare provider if you experience these symptoms.

The most common side effects of Stimufend are pain in the bones, arms, and legs.

These are not all the possible side effects of Stimufend. Call your healthcare provider for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.
