PROMACTA® (eltrombopag) is the only treatment of its kind that offers convenient once-daily oral dosing for pediatric patients with persistent or chronic immune thrombocytopenia (ITP). Most young children start PROMACTA on 25 mg once daily. Your child’s doctor will work with you to find which strength and formulation work best for your child over the long term.


PROMACTA comes in both an oral tablet and oral suspension:


12.5 mg, 25 mg, 50 mg, 75 mg


12.5 mg, 25 mg


You and your child can choose which way is best to take PROMACTA.


PROMACTA can be taken without a meal or with a meal low in calcium (≤50 mg).
PROMACTA should be taken 2 hours before or 4 hours after taking medications like antacids, mineral supplements, or foods that are high in calcium.
Weekly doctor visits aren’t required for administration of PROMACTA.
How to Mix and Give PROMACTA for Oral Suspension

With PROMACTA, you don’t have to build your child’s life around treatment administration. You and your child decide when to take it. Once you find a time that works, simply stick to that time, all the time. Here are some ideas to get you started creating a schedule.

Too much calcium (more than 50 mg) stops PROMACTA from working properly. To get the full benefit of PROMACTA, you need to be careful to avoid eating calcium-rich foods such as dairy products (yogurt, cheese, milk, ice cream), calcium-fortified foods (some orange juice, dry cereal, and bread), and certain fruits and vegetables.
