Promacta Patient Information Including Side Effects

Brand Names: Promacta

Generic Name: eltrombopag (Pronunciation: el TROM boe pag)

What is eltrombopag (Promacta)?

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 also used to prevent bleeding in people with chronic hepatitis C who are treated with an interferon (such as Intron A, Infergen, Pegasys, PegIntron, Rebetron, Redipen, or Sylatron).

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.

What are the possible side effects of eltrombopag (Promacta)?

Get emergency medical help if you have any of these signs of an allergic reaction: hives; difficult breathing; swelling of your face, lips, tongue, or throat.

  • fever, chills, body aches, flu symptoms, unusual weakness or tired feeling;

  • pain, swelling, warmth, or redness in one or both legs;
  • easy bruising, unusual bleeding (nose, mouth, vagina, or rectum), purple or red pinpoint spots under your skin; or

What is the most important information I should know about eltrombopag (Promacta)?

Before you take eltrombopag tell your doctor if you have kidney disease, blood cancer, a bone marrow disorder, high platelet levels, liver problems (if you are not being treated for hepatitis C), a history of cataracts or blood clot, if your spleen has been removed, or if you are of East Asian descent. Also tell your doctor about all other medications you use.

Take eltrombopag on an empty stomach, at least 1 hour before or 2 hours after a meal. Do not take this medication with milk. Avoid all dairy products or products that contain calcium (including fortified fruit juice) for at least 4 hours before or after you take eltrombopag.

Avoid taking other medications, including antacids or vitamin and mineral supplements, within 4 hours before or after you take eltrombopag.

While using eltrombopag, you may need frequent blood tests at your doctor's office.

Eltrombopag may cause liver damage. Stop using eltrombopag and call your doctor at once if you have nausea, upper stomach pain, itching, loss of appetite, dark urine, clay-colored stools, or jaundice (yellowing of the skin or eyes).

After you stop taking eltrombopag, your risk of bleeding may be even higher than it was before you started treatment. Be extra careful to avoid cuts or injury for at least 4 weeks after you stop taking eltrombopag. Your blood will need to be tested weekly during this time.
