What is Nplate?

Nplate is a man-made protein medicine used to treat low blood platelet counts in adults with chronic immune thrombocytopenia  (ITP), when certain other medicines, or surgery to remove your spleen, have not worked well enough.

Nplate is not for use in people with a precancerous condition called myelodysplastic syndrome (MDS) or low platelet count caused by any condition other than chronic (lasting a long time) immune thrombocytopenia (ITP).

Nplate is only used if your low platelet count and medical condition increase your risk of bleeding.

Nplate is used to try to keep your platelet count about 50,000 per microliter in order to lower the risk for bleeding. Nplate is not used to make your platelet count normal.

It is not known if Nplate works or if it is safe in people under the age of 18.
