What is eltrombopag?
Eltrombopag is a man-made form of a protein that increases production of platelets (blood-clotting cells) in your body. Eltrombopag can lower the risk of bleeding by increasing platelets in your blood.
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 for use in adults and children who are at least 1 year old, after other medicines have been tried without success.
Eltrombopag is also used to treat severe aplastic anemia in adults after other medicines have been tried without success.
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.
Call your doctor at once if you have signs of liver problems: nausea, upper stomach pain, confusion, tired feeling, loss of appetite, dark urine, clay-colored stools, jaundice (yellowing of the skin or eyes).
