Deferasirox

WHY is this medicine prescribed?

Deferasirox is used to treat adults and children 2 years of age and older who have too much iron in their body because they received many blood transfusions. It is also used to treat adults and children 10 years of age and older who have too much iron in their body because of a genetic blood disorder called non–transfusion-dependent thalassemia (NTDT). Deferasirox is in a class of medications called iron chelators. It works by attaching to iron in the body so that it can be excreted (removed from the body) in feces.

HOW should this medicine be used?

Deferasirox comes as a tablet, granules, and a tablet for suspension (a tablet to dissolve in liquid) to take by mouth. It should be taken on an empty stomach once a day, at least 30 minutes before eating, The tablets and granules can also be taken with a light meal such as a whole wheat English muffin with jelly and skim milk, or a small turkey sandwich on whole wheat bread. Take deferasirox at around the same time every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take deferasirox exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.

Different deferasirox products are absorbed by the body in different ways and cannot be substituted for one another. If you need to switch from one deferasirox product to another, your doctor may need to adjust your dose. Each time you receive your medication, check to be sure that you have received the deferasirox product that was prescribed for you. Ask your pharmacist if you are not sure that you received the right medication.

If you have trouble swallowing the tablet, you may crush the tablet and mix with a soft food such as yogurt or applesauce immediately before taking. However, do not crush the 90 mg tablet (Jadenu) using a professional crushing device that has jagged edges.
