What is eltrombopag?
Eltrombopag is a man-made form of a protein that increases production of platelets (blood-clotting cells) in your body.
Eltrombopag is used to prevent bleeding episodes in people with chronic immune thrombocytopenic purpura (ITP), a bleeding condition caused by a lack of platelets in the blood.
Eltrombopag is usually given after other medications or surgery have been tried without successful treatment of symptoms.

Eltrombopag is not a cure for ITP and it will not make your platelet counts normal if you have this condition. |
Eltrombopag may also be used for purposes not listed in this medication guide.
