How should I take eltrombopag (Promacta)?
Eltrombopag is available only under a special program called PROMACTA Cares. You must be enrolled in this program and sign all required agreements in order to take the medication. Read all program brochures and agreements carefully.
Take exactly as prescribed by your doctor. Do not take in larger or smaller amounts or for longer than recommended. Follow the directions on your prescription label.
Your doctor may occasionally change your dose to make sure you get the best results.
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.
Taking eltrombopag long-term can cause harmful effects on your bone marrow that may result in serious blood cell disorders.
To be sure this medication is not causing harmful effects, your blood and liver function will need to be tested often. Your eyes may also need to be checked for signs of cataract formation. Visit your doctor regularly.
It may take up to 4 weeks of taking this medicine before it is completely effective in preventing bleeding episodes. Keep taking the medication as directed and tell your doctor if you have any bruising or bleeding episodes after 4 weeks of treatment.

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.
