If you experience any of the following symptoms, call your doctor immediately: decreased urination, swelling in the ankles, legs, or feet, excessive tiredness, shortness of breath, and confusion.

Deferasirox may also cause serious or life threatening bleeding in the stomach or intestines. The risk that you will develop severe bleeding in the stomach or intestines may be greater if you are elderly, or are very sick from a blood condition. Tell your doctor if you have or have ever had a low level of platelets (a type of blood cell that is needed to control bleeding), or if you are taking any of the following medications: anticoagulants (blood thinners) such as warfarin (Coumadin, Jantoven); aspirin or other nonsteroidal anti-inflammatory medications (NSAIDs) such as ibuprofen (Advil, Motrin, others) and naproxen (Aleve, Naprosyn, others); certain medications to strengthen the bones including alendronate (Binosto, Fosamax), etidronate, ibandronate (Boniva), pamidronate, risedronate (Actonel, Atelvia), and zoledronic acid (Reclast, Zometa); or steroids such as dexamethasone, methylprednisolone (A-methapred, Depo-medrol, Medrol, Solu-medrol), or prednisone (Rayos). If you experience any of the following symptoms, call your doctor immediately: burning stomach pain, vomit that is bright red or looks like coffee grounds, bright red blood in stools, or black or tarry stools.
Keep all appointments with your doctor and the laboratory. Your doctor will order laboratory tests before and during your treatment to be sure it is safe for you to take deferasirox and to see if you are developing these serious side effects.
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.
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.
