Patient Education

Romiplostim Injection


Romiplostim injection is used to increase the number of platelets (cells that help the blood to clot) in order to decrease the risk of bleeding in adults who have immune thrombocytopenia (ITP; idiopathic thrombocytopenic purpura; an ongoing condition that may cause easy bruising or bleeding due to an abnormally low number of platelets in the blood). Romiplostim injection is also used to increase the number of platelets in order to decrease the risk of bleeding in children at least 1 year of age who have had ITP for at least 6 months. Romiplostim injection should only be used in adults and children 1 year of age or older who cannot be treated or have not been helped by other treatments, including other medications or surgery to remove the spleen. Romiplostim injection should not be used to treat people who have low platelet levels caused by myelodysplastic syndrome (a group of conditions in which the bone marrow produces blood cells that are misshapen and does not produce enough healthy blood cells) or any other conditions that cause low platelet levels other than ITP. Romiplostim injection is used to increase the number of platelets enough to lower the risk of bleeding, but it is not used to increase the number of platelets to a normal level. Romiplostim is in a class of medications called thrombopoietin receptor agonists. It works by causing the cells in the bone marrow to produce more platelets.
