How to fit PROMACTA into your family's lifestyle

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.

What does calcium have to do with it?

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.
