Romiplostim, sold under the brand name Nplate among others, is a medication used to treat immune thrombocytopenic purpura (ITP) and acute radiation syndrome. In ITP it may be used when corticosteroids, immunoglobulins, or splenectomy are not effective. It is given by injection under the skin.

Common side effects include joint pain, trouble sleeping, abdominal pain, headache, and tiredness. Other side effects include blood cancer, blood clots, and bone marrow fibrosis. Safety in pregnancy is unclear. It works to stimulate platelet production by activating the thrombopoietin receptor.

Romiplostim was approved for medical use in the United States in 2008 and Europe in 2009. In the United Kingdom a 125 mcg vial costs the NHS about £240 as of 2021. This amount in the United States costs about 1,100 USD.
