Leukine

Generic name: sargramostim

What is Leukine?

Leukine is a man-made form of granulocyte-macrophage colony-stimulating factor (GM-CSF). GM-CSF is a substance produced by the body. It stimulates the growth of certain white blood cells that are important in the body’s fight against infection.

Acute Radiation Syndrome: The effectiveness of Leukine for this use was only studied in animals because it could not be studied in people.

Who should not use Leukine?

Do not take Leukine if you have had a serious allergic reaction to human GM-CSF, such as sargramostim, products that are made from yeast, or any of the ingredients in Leukine. See the end of this leaflet for a complete list of ingredients in Leukine.

What should I tell my healthcare provider before using Leukine?

Before receiving Leukine, tell your healthcare provider about all your medical conditions, including if you:

  • have heart or lung disease
  • are allergic to benzyl alcohol
  • are pregnant or plan to become pregnant. It is not known if Leukine will harm your unborn baby. See “What are the possible side effects of Leukine?” Talk to your healthcare provider about the type of Leukine that is right for you.
  • are breastfeeding or plan to breastfeed. It is not known if Leukine passes into your breast milk. Do not breast feed during treatment and for at least 2 weeks after your last dose of Leukine.

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

How should I use Leukine?

  • Leukine comes in two ways: as a solution or as a powder to be mixed for injection.
  • Leukine 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, see the detailed Instructions for use that comes with your Leukine for information on how to draw up and inject a dose of Leukine.
  • If your healthcare provider gives you Leukine for injection (powder) to be mixed, carefully follow your healthcare provider’s instructions on how to store, mix, draw up and inject the medicine.
  • You and your caregiver should be shown how to prepare and inject Leukine before you use it, by your healthcare provider.
  • Your healthcare provider will tell you how much Leukine to inject and when to inject it. Do not change your dose or stop Leukine unless your healthcare provider tells you to.
  • If you are also receiving chemotherapy or radiation therapy, your dose of Leukine should be injected at least 24 hours before or 24 hours after your dose of chemotherapy and at least 24 hours before your dose of radiation therapy. Your healthcare provider will do blood tests to monitor your white blood cell count and, if necessary, adjust your Leukine dose.
  • If you are receiving Leukine because you have been suddenly (acutely) exposed to an amount of radiation that can affect your bone marrow (Acute Radiation Syndrome), you will need to have blood tests about every 3 days during treatment with Leukine to check your white blood cell count until it returns to normal.
  • If your child needs to receive Leukine for Acute Radiation Syndrome, follow your healthcare provider’s instructions. Leukine injection contains the preservative benzyl alcohol.
  • If you miss a dose of Leukine, talk to your healthcare provider about when you should give your next dose.

What are the possible side effects of Leukine?

Leukine may cause serious side effects, including:

  • Serious allergic reactions. Leukine can cause serious allergic reactions that can be severe. Get medical help right away if you get any of the following signs or symptoms of a serious allergic reaction with Leukine, including: skin rash over your entire body, hives, trouble breathing, wheezing, swelling around your mouth or eyes, a fast heartbeat, sweating, and dizziness or feeling faint.
  • Infusion related reactions. When Leukine is given as an infusion, it can cause reactions during or soon after an infusion. Tell your healthcare provider or nurse right away if you develop trouble breathing, skin flushing, a fast pulse, dizziness or you feel faint during or soon after your infusion.
  • Too much body fluid (fluid retention) and Capillary Leak Syndrome. Leukine can cause you to have too much fluid in your body, and fluid may leak from blood vessels into your body’s tissues. This can happen anywhere in your body, including around your heart and lungs. 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 of your feet or ankles, and are urinating less than usual
    • swelling of your stomach area (abdomen) and feeling of fullness
    • sudden weight gain
    • swollen legs or feet
    • trouble breathing
    • dizziness or feeling faint
    • a general feeling of tiredness
  • Abnormal heart rhythm. An abnormal heart rhythm may happen during treatment with Leukine, especially in people with a history of an abnormal heart rhythm.
  • Increased white blood cell count. Leukine can cause your white blood cell count to increase too high (leukocytosis). Your healthcare provider will check your blood during treatment with Leukine.
  • Risks of using Leukine in newborns, babies born with a low birth weight, and in pregnant women. Some forms of Leukine may contain the preservative benzyl alcohol. Medicines that contain benzyl alcohol, including Leukine, can cause serious side effects that can lead to death in newborns and babies born with a low birth weight. Avoid using Leukine containing benzyl alcohol in newborns, babies born with a low birth weight, and in pregnant women. If Leukine needs to be given to your newborn or baby with a low birth weight, or in pregnant women, talk to your healthcare provider about this risk and which form of Leukine to use.
