Neulasta is a prescription medication used to reduce the risk of infection in people receiving strong chemotherapy that decreases the number of infection-fighting white blood cells known as neutrophils.
Neulasta belongs to a group of drugs called colony stimulating factors. These work by helping the body make more neutrophils. Neutrophils are needed to fight infection.
This medication comes in an injectable form and is injected just under the skin, usually once per chemotherapy cycle.
Common side effects of Neulasta include muscle and bone pain.
