Jadenu (deferasirox) is a prescription medicine used to lower iron levels in people with chronic iron overload. This condition often develops in patients who receive frequent blood transfusions for diseases like thalassemia, sickle cell anemia, or certain other chronic anemias. By reducing excess iron, Jadenu helps protect vital organs such as the heart, liver, and pancreas from long-term damage.
In this easy-to-read guide, you’ll learn what Jadenu is, how it works, when doctors prescribe it, how to take it safely, possible side effects, precautions, and answers to some of the most common questions people search online.

What is Jadenu?
Jadenu (active ingredient: deferasirox) belongs to a class of medicines called iron chelators. It works by binding to excess iron in the body and allowing it to be removed naturally, mainly through the stool.
Jadenu is available in two main forms:
- Jadenu tablets (film-coated, taken with or without a light meal)
- Jadenu Sprinkle granules (mixed with soft food or liquids, usually for those who have difficulty swallowing tablets)
It is often prescribed as a more convenient alternative to Exjade, another deferasirox-based medication.

- Follow all directions on your prescription label and instructions provided by your healthcare team.
- Do not change your dose or stop taking Jadenu unless instructed by your doctor.
- Jadenu may cause serious liver, kidney, or gastrointestinal side effects in some patients. Regular monitoring with blood tests is required.
Seek medical attention right away if you experience symptoms such as severe stomach pain, blood in stools, vomiting blood, yellowing of skin/eyes, or unusual tiredness.

Popular FAQ

Both contain deferasirox, but Jadenu is easier to take because it can be swallowed directly, while Exjade tablets must be dissolved in liquid.
How long do I need to take Jadenu?
Treatment is long-term and depends on your iron levels. Many patients take it for months or years, with dose adjustments based on regular monitoring.
Does Jadenu cure thalassemia or sickle cell disease?
No. Jadenu does not cure the underlying disease; it only manages iron overload from blood transfusions.
Can children take Jadenu?
Yes, but only if prescribed by a doctor, with careful dose adjustments and monitoring.
Final Thoughts
Jadenu is an important medicine for managing chronic iron overload and preventing organ damage in patients who need regular blood transfusions. While highly effective, it requires close monitoring to avoid serious side effects.
