What is oprelvekin (Neumega)?
Oprelvekin is a protein that stimulates production of platelets in the blood. Platelets are important for proper clotting of the blood and for wound healing.
Oprelvekin is used to prevent platelets from becoming dangerously low in certain people receiving chemotherapy that can result in bone marrow suppression or the need for blood platelet transfusions.
Oprelvekin may also be used for other purposes not listed in this medication guide.
