Deferasirox may cause severe and sometimes fatal kidney problems or liver problems. The risk may be greater in patients who already have kidney or liver problems. Lab tests, including kidney and liver function, will be performed while you use deferasirox to check for these problems. Be sure to keep all doctor and lab appointments.
Deferasirox may also cause severe and sometimes fatal stomach or bowel bleeding. The risk may be greater in elderly patients who have advanced blood or bone marrow cancer and/or low blood platelet counts.
Tell your doctor if you develop symptoms of kidney problems (eg, decreased urination) or liver problems (eg, yellowing of the skin or eyes; dark urine; pale stools; severe or persistent nausea, stomach pain, or loss of appetite). Tell your doctor if you develop symptoms of stomach or bowel bleeding (eg, stomach pain; black, tarry stools; vomit that looks like coffee grounds).
Deferasirox is used for:
Treating high levels of iron in the blood.
Deferasirox is an iron-chelating agent. It works by binding to the extra iron in the blood and removing it from the body.
Do NOT use deferasirox if:
- you are allergic to any ingredient in deferasirox
- you have severe kidney or liver problems or very low blood platelet levels
- you have certain blood or bone marrow problems (high-risk MDS) or advanced cancer
Contact your doctor or health care provider right away if any of these apply to you.
