Nplate Key Facts
What is Nplate?
Nplate is the brand name for romiplostim subcutaneous injection.
What dosages is Nplate available in?
Nplate is available as a 125 mcg, 250 mcg or 500 mcg single-dose vial.
What is Nplate used for?
Nplate is a thrombopoietin receptor agonist and is used for the following:
- Low platelet levels in the blood caused by attacks from the immune system (immune thrombocytopenic purpura or ITP)
- Blood problems caused by too much radiation (hematopoietic syndrome of acute radiation syndrome).
How does Nplate work?
Nplate is a thrombopoietin receptor agonist. This means that it acts like the hormone thrombopoietin that’s responsible for the production of your platelets. Platelets are blood cells that help you form clots to prevent bleeds. When your platelet levels are too low, you’re at higher risk for bleeds. Nplate is used to raise the amount of platelets in people with immune thrombocytopenia, a condition where your platelets are attacked by your immune system. Nplate is also used to raise platelet levels in people whose platelets have been destroyed by too much radiation exposure. By raising the platelet levels, this medication helps lower the risk for bleeding.
How do I take Nplate?
Nplate is dosed as follows:
- This medication must be given by a healthcare provider. Your provider will determine your dose of Nplate based on your weight
- ITP: The typical starting dose is 1 mcg/kg injected under the skin once weekly. Your provider will adjust your dose based on your platelet level
- Blood problems from too much radiation: The typical dose is 10 mcg/kg injected under the skin as a one-time dose by your provider
