(el trom' boe pag)
If you have chronic hepatitis C (an ongoing viral infection that may damage the liver) and you take eltrombopag with medications for hepatitis C called interferon (Peginterferon, Pegintron, others) and ribavirin (Copegus, Rebetol, Ribasphere, others), there is an increased risk that you will develop serious liver damage. If you experience any of the following symptoms, call your doctor immediately: yellowing of the skin or eyes, dark urine, excessive tiredness, pain in the upper right part of the stomach, swelling of the stomach area, or confusion.
Your doctor or pharmacist will give you the manufacturer's patient information sheet (Medication Guide) when you begin treatment with eltrombopag and each time you refill your prescription. Read the information carefully and ask your doctor or pharmacist if you have any questions. You can also visit the Food and Drug Administration (FDA) website (http://www.fda.gov/Drugs/DrugSafety/ucm085729.htm) or the manufacturer's website to obtain the Medication Guide.
Talk to your doctor about the risks of taking eltrombopag.
WHY is this medicine prescribed?
Eltrombopag is used to increase the number of platelets (cells that help the blood clot) to decrease the risk of bleeding in adults and children 1 year of age and older who have chronic immune thrombocytopenia (ITP; an ongoing condition that may cause unusual bruising or bleeding due to an abnormally low number of platelets in the blood) and who have not been helped or cannot be treated with other treatments, including medications or surgery to remove the spleen. Eltrombopag is also used to increase the number of platelets in people who have hepatitis C (a viral infection that may damage the liver) so that they can begin and continue treatment with interferon (Peginterferon, Pegintron, others) and ribavirin (Rebetol). Eltrombopag is also used to treat people with aplastic anemia (condition in which the body does not make enough new blood cells) who have not been helped with other medications. It is used to increase the number of platelets enough to decrease the risk of bleeding in people with ITP or to allow treatment with interferon and ribavirin in people with hepatitis C, but it is not used to increase the number of platelets to a normal level. Eltrombopag should not be used to treat people who have low numbers of platelets due to conditions other than ITP or hepatitis C. Eltrombopag is in a class of medications called thrombopoietin receptor agonists. It works by causing the cells in the bone marrow to produce more platelets.
HOW should this medicine be used?
Eltrombopag comes as a tablet and as a powder for oral suspension (liquid) to take by mouth. It is usually taken once a day on an empty stomach, at least 1 hour before or 2 hours after eating. Take eltrombopag at around the same time every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take eltrombopag exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Take eltrombopag at least 2 hours before or 4 hours after you eat or drink foods that contain a lot of calcium, such as dairy products, calcium-fortified juices, cereals, oatmeal, and breads; trout; clams; leafy green vegetables such as spinach and collard greens; and tofu and other soy products. Ask your doctor if you are not sure if a food contains a lot of calcium. You may find it helpful to take eltrombopag close to the beginning or end of your day so that you will be able to eat these foods during most of your waking hours.
Swallow the tablets whole. Do not split, chew, or crush them and mix them into food or liquids.
If you are taking the powder for oral suspension, carefully read the manufacturer's instructions for use that comes with the medication. These instructions describe how to prepare and measure your dose. Mix the powder with cool or cold water before use. Do not mix the powder with hot water. Immediately after preparation, swallow the dose. If it is not taken within 30 minutes or if there is remaining liquid, dispose of the mixture in the trash (do not pour it down the sink).
Do not allow the powder to touch your skin. If you spill the powder on your skin, wash it off immediately with soap and water. Call your doctor if you have a skin reaction or if you have any questions.
Your doctor will probably start you on a low dose of eltrombopag and adjust your dose depending on your response to the medication. At the beginning of your treatment, your doctor will order a blood test to check your platelet level once every week. Your doctor may increase your dose if your platelet level is too low. If your platelet level is too high, your doctor may decrease your dose or may not give you eltrombopag for a time. After your treatment has continued for some time and your doctor has found the dose of eltrombopag that works for you, your platelet level will be checked less often. Your platelet level will also be checked weekly for at least 4 weeks after you stop taking eltrombopag.
If you have chronic ITP, you may receive other medications to treat your condition along with eltrombopag. Your doctor may decrease your dose of these medications if eltrombopag works well for you.
Eltrombopag does not work for everyone. If your platelet level does not increase enough after you have taken eltrombopag for some time, your doctor may tell you to stop taking eltrombopag.
Eltrombopag may help to control your condition but will not cure it. Continue to take eltrombopag even if you feel well. Do not stop taking eltrombopag without talking to your doctor.

This medication may be prescribed for other uses; ask your doctor or pharmacist for more information.
What SPECIAL PRECAUTIONS should I follow?
Before taking eltrombopag,
- tell your doctor and pharmacist if you are allergic to eltrombopag, any other medications, or any of the ingredients in eltrombopag tablets. Ask your pharmacist or check the Medication Guide for a list of the ingredients.

Be sure to mention any of the following: anticoagulants (blood thinners) such as warfarin (Coumadin, Jantoven); bosentan (Tracleer); cholesterol-lowering medications (statins) such as atorvastatin (Lipitor, in Caduet), fluvastatin (Lescol), pitavastatin (Livalo), pravastatin (Pravachol), rosuvastatin (Crestor), and simvastatin (Zocor, in Simcor, in Vytorin); ezetimibe (Zetia, in Vytorin); glyburide (Diabeta, Glynase, in Glucovance); imatinib (Gleevec); irinotecan (Camptosar); olmesartan (Benicar, in Azor, in Tribenzor, others); lapatinib (Tykerb); methotrexate (Trexall); mitoxantrone; repaglinide (Prandin, in PrandiMet): rifampin (Rimactane, Rifadin, in Rifamate, Rifater); sulfasalazine (Azulfidine); topotecan (Hycamtin), and valsartan (in Diovan HCT, in Entresto, in Exforge). Your doctor may need to change the doses of your medications or monitor you carefully for side effects. Many other medications may also interact with eltrombopag, so be sure to tell your doctor about all the medications you are taking, even those that do not appear on this list.
- if you are taking antacids containing calcium, aluminum, or magnesium (Maalox, Mylanta, Tums) or vitamin or mineral supplements containing calcium, iron, zinc or selenium, take them 2 hours before or 4 hours after you take eltrombopag.
- tell your doctor if you are of East Asian (Chinese, Japanese, Taiwanese, or Korean) descent and if you have or have ever had a cataract (clouding of the lens of the eye that may cause vision problems), blood clots, any condition that increases the risk that you will develop a blood clot, bleeding problems, or liver or kidney disease. Also tell your doctor if you have had surgery to remove your spleen.

- if you are having surgery, including dental surgery, tell the doctor or dentist that you are taking eltrombopag.
