Important Safety Information for PROMACTA^® (eltrombopag)

What is the most important information I should know about PROMACTA?

PROMACTA can cause serious side effects, including:

Liver problems.

PROMACTA may increase your risk of liver problems that may be severe and possibly life-threatening. Your health care provider will do blood tests to check your liver function before you start taking PROMACTA and during treatment. Your health care provider may stop your treatment with PROMACTA if you have changes in your liver function blood tests.

Tell your health care provider right away if you have any of these signs and symptoms of liver problems:

yellowing of the skin or the whites of the eyes (jaundice)
unusual darkening of the urine
unusual tiredness
right upper stomach area (abdomen) pain
confusion
swelling of the stomach area (abdomen)

What are the possible side effects of PROMACTA?

PROMACTA may cause serious side effects, including:

Worsening of a precancerous blood condition to a blood cancer called acute myelogenous leukemia (AML). PROMACTA is not for treatment of people with a precancerous condition called myelodysplastic syndromes (MDS). If you have MDS and receive PROMACTA, your MDS condition may worsen and become AML. If MDS worsens to become AML, you may die sooner from AML

High platelet counts and higher risk for blood clots. Your risk of getting a blood clot is increased if your platelet count is too high during treatment with PROMACTA. Your risk of getting a blood clot may also be increased during treatment with PROMACTA if you have normal or low platelet counts. You may have severe problems or die from some forms of blood clots, such as clots that travel to the lungs or that cause heart attacks or strokes. Your health care provider will check your blood platelet counts and change your dose or stop PROMACTA if your platelet counts get too high. Tell your health care provider right away if you have signs and symptoms of a blood clot in the leg such as swelling, pain, or tenderness.

People with chronic liver disease may be at risk for a type of blood clot in the stomach area. Tell your health care provider right away if you have stomach area pain that may be a symptom of this type of blood clot

New or worsened cataracts (a clouding of the lens in the eye). New or worsened cataracts have happened in people taking PROMACTA. Your health care provider will check your eyes before and during your treatment with PROMACTA. Tell your health care provider about any changes in your eyesight while taking PROMACTA

What should I tell my health care provider before taking PROMACTA?

Before you take PROMACTA, tell your health care provider about all of your medical conditions, including if you:

have liver problems
have a precancerous condition called MDS or a blood cancer
have or have had a blood clot
have a history of cataracts
have had surgery to remove your spleen (splenectomy)
have bleeding problems
are of Asian ancestry (such as Chinese, Japanese, Taiwanese, or Korean). You may need a lower dose of PROMACTA
are pregnant or plan to become pregnant. It is not known if PROMACTA will harm an unborn baby. Tell your health care provider if you become pregnant or think you may be pregnant during treatment with PROMACTA. If you are a woman who is able to become pregnant, you must use reliable birth control (contraception) while taking PROMACTA and for at least 7 days after you stop taking PROMACTA. Talk to your health care provider about options of effective birth control methods that may be right for you during this time
are breastfeeding or plan to breastfeed. You should not breastfeed during treatment with PROMACTA. Talk to your health care provider about the best way to feed your baby during this time

Tell your health care provider about all the medicines you take, including prescription and over-the-counter medicines, vitamins, and herbal supplements. PROMACTA may affect the way certain medicines work. Certain other medicines may affect the way PROMACTA works.

Especially tell your health care provider if you take:

certain medicines used to treat high cholesterol, called “statins”
a blood thinner medicine

Certain medicines may keep PROMACTA from working correctly. Take PROMACTA at least 2 hours before or 4 hours after taking these products:

antacids used to treat stomach ulcers or heartburn
multivitamins, mineral supplements, or products that contain iron, calcium, aluminum, magnesium, selenium, and zinc

Ask your health care provider if you are not sure if your medicine is one that is listed above.

nausea
diarrhea
upper respiratory tract infection (symptoms may include runny nose, stuffy nose, and sneezing)
vomiting
urinary tract infection

Approved Uses for PROMACTA^® (eltrombopag)
PROMACTA is a prescription medicine used to treat adults and children 1 year and older with low blood platelet counts due to chronic immune thrombocytopenia (ITP) when other medicines to treat your ITP or surgery to remove the spleen have not worked well enough. PROMACTA is used to try to raise platelet counts in order to lower your risk for bleeding.

PROMACTA is not used to make platelet counts normal.

PROMACTA is for the treatment of certain people with low platelet counts caused by chronic ITP, chronic hepatitis C virus (HCV), or severe aplastic anemia (SAA), not for a precancerous condition called myelodysplastic syndromes (MDS) or low platelet counts caused by other conditions or diseases.

It is not known if PROMACTA is safe and effective in children with chronic HCV or previously treated SAA, in children younger than 1 year with ITP, or children younger than 2 years when used in combination with standard immunosuppressive therapy as the first treatment for SAA.

What is PROMACTA?

PROMACTA is the only oral prescription platelet booster used to treat adults and children 1 year and older with chronic immune thrombocytopenia (cITP)
PROMACTA is used after other ITP treatments (such as steroids or IVIg) have failed to keep your platelets up or have caused too many side effects
PROMACTA is the only platelet booster that comes in a once-daily tablet and as an oral suspension

What is cITP?

Chronic immune thrombocytopenia (cITP) is a rare blood condition. People with cITP have not had enough platelets in their blood for 6 months or more.

A low number of platelets can lead to easy bruising and bleeding. Fortunately, cITP can be managed with treatment, such as PROMACTA.

To learn more about cITP, go here.

How is PROMACTA different from other cITP treatments?

PROMACTA is the only platelet booster that comes in a tablet or an oral suspension you can take once a day
Platelet boosters work differently from other cITP treatments: Instead of hurting the immune system, they work with your body to create more platelets so it can make up for the ones it has destroyed. This in turn helps raise platelet counts and improve bruising and bleeding
The efficacy of PROMACTA has been studied and proven in adults for up to 7 years

Who can take PROMACTA?
