Uses
This medication is used to treat a certain blood disorder (idiopathic thrombocytopenia purpura - ITP) in which the blood does not clot properly due to a lack of platelets. Platelets are a type of blood cell needed to form blood clots and prevent bleeding. Romiplostim decreases your risk of bleeding by increasing the number of platelets. Romiplostim is also given to people whose ability to make platelets is reduced due to exposure to large amounts of radiation. Romiplostim acts like a certain natural substance (thrombopoietin) that causes the body to produce platelets.

If someone has overdosed and has serious symptoms such as passing out or trouble breathing, call 911. Otherwise, call a poison control center right away. US residents can call 1-800-222-1222. Canada residents can call 1-844-764-7669. Symptoms of overdose may include: pain/swelling/warmth in the groin/calf, sudden shortness of breath, coughing up blood, sudden dizziness/fainting, chest/jaw/left arm pain, trouble speaking, weakness on one side of the body, vision problems/changes.
