This medication is given to those whose ability to make white blood cells has been reduced. This medication stimulates the blood system (bone marrow) to make white blood cells, which help your body fight infections. Sargramostim (also known as GM-CSF, or granulocyte-macrophage colony stimulating factor) is a man-made version of a certain natural substance found in the body that also stimulates the bone marrow to make white blood cells. It is produced using a certain yeast (Saccharomyces cerevisiae).
Do not shake this medication. Doing so may make the drug ineffective.
Follow your doctor's directions exactly. This medication is given by infusion into a vein (IV) or by injection under the skin as directed by your doctor, usually once a day until the proper blood counts are reached. Dosage is based on your medical condition, body size, lab results, and response to treatment. Use the exact amount of drug prescribed by your doctor. If you use less than the prescribed amount, your body may not produce enough white blood cells to protect your body against infections. If you use more than the prescribed amount, your body may produce too many white blood cells.
Use this medication regularly in order to get the most benefit from it. To help you remember, use it at the same time each day.
When injecting under the skin, a new injection site should be chosen for each dose. This will help prevent soreness. Never inject sargramostim into skin that is tender, red, bruised, or hard or has scars or stretch marks.
If you are giving this medication to yourself at home, learn all preparation and usage instructions from your health care professional.

Before using, check this product visually for particles or discoloration. If either is present, do not use the liquid. Learn how to store and discard medical supplies safely.
If you are receiving chemotherapy for cancer, you should not be given sargramostim at the same time. You should receive sargramostim either before or after the chemotherapy, depending on your blood count results and your doctor's directions.
Aching in the bones and muscles, chills, or headache may occur. Taking a non-aspirin pain reliever such as acetaminophen may help. Ask your doctor or pharmacist for more details.

If any of these effects persist or worsen, tell your doctor or pharmacist promptly.
