This medication is used to prevent very low platelet counts (thrombocytopenia) and to reduce the need for platelet transfusions after certain chemotherapy treatments. Platelets help your blood clot when you are cut or injured. Having too few platelets can cause you to bruise easier and/or bleed longer when you get cut or injured. This medication causes your body to make more platelets.
