Rarely, eltrombopag has caused severe (possibly fatal) liver problems. Get medical help right away if you develop symptoms of liver problems (such as persistent nausea, stomach/abdominal pain, dark urine, yellowing eyes/skin).
People with a certain liver problem (chronic hepatitis C) who are taking this medication with ribavirin and interferon may sometimes experience worsening of their liver problem. Get medical help right away if you have any very serious side effects, including symptoms of liver problems, stomach/abdominal swelling, or mental/mood changes. Talk with your doctor about the risks and benefits of this medication.
To help decrease the risk of liver problems, your doctor will order laboratory tests (liver function tests). Do every laboratory test ordered by your doctor and keep all medical appointments. Your doctor will order liver tests before you start eltrombopag, every 2 weeks as the dose is changed, and monthly after you have been taking the same dose for a while.
This medication is used to treat low platelet levels in people who have a certain blood disorder called chronic immune (idiopathic) thrombocytopenia purpura (ITP) or who have chronic hepatitis C. It may also be used to treat people with a certain blood disorder (aplastic anemia). Platelets are a type of blood cell needed to form blood clots and prevent bleeding. Eltrombopag decreases your risk of bleeding by increasing the number of platelets. Eltrombopag acts like a certain natural substance (thrombopoietin) that causes the body to produce platelets.
Read the Medication Guide provided by your pharmacist before you start using eltrombopag and each time you get a refill. If you have any questions, consult your doctor or pharmacist.
Take this medication by mouth, usually once daily or as directed by your doctor. Take on an empty stomach, either 1 hour before a meal or 2 hours after a meal.
Take this medication at least 4 hours before or after taking any products that contain magnesium, aluminum, or calcium. Some examples include antacids, vitamins/minerals, quinapril, certain forms of didanosine (chewable/dispersible buffered tablets or pediatric oral solution), and sucralfate. Follow the same instructions with dairy products (such as milk, yogurt), calcium-enriched juice, bismuth subsalicylate, iron, selenium, and zinc. These products bind with eltrombopag, preventing its full absorption.
Take this medication regularly to get the most benefit from it. To help you remember, take it at the same time each day. Dosage is based on your medical condition, response to treatment, and laboratory tests. Your doctor will order blood tests (platelet counts) to find the right dose for you. Keep all medical/lab appointments. Follow your doctor's directions carefully. If you are of Asian descent or if you have liver problems, your doctor may direct you to start with a lower dose because you may be more sensitive to its effects.
Your risk of bleeding may increase when you stop using eltrombopag. After your last dose, your doctor should order a blood test once a week for at least 4 weeks to check your platelet count. Tell your doctor immediately if you develop any bleeding/bruising.
Tell your doctor if your condition (bleeding/bruising) persists or worsens.
