How does this medication work? What will it do for me?
Deferiprone belongs to the class of medications called iron-chelating agents. It is used to reduce the amount of iron in the blood for people with thalassemia, when other treatments have not worked.
Thalassemia is a condition where the body cannot produce normal red blood cells. Treatment of thalassemia involves regular blood transfusions to provide the body with the red blood cells necessary for normal functioning. Regular transfusions cause too much iron to build up in the body, which can be harmful. Deferiprone binds to the extra iron, removing it from the body.
This medication may be available under multiple brand names and/or in several different forms.

How should I use this medication?
The usual dose of deferiprone is based on body weight. Your doctor will calculate the dose as 25 to 33 mg per kilogram of body weight. This dose is then taken by mouth, three times a day.
Deferiprone can be taken with or without food. If you experience upset stomach with this medication, take it with food. People who experience severe nausea, vomiting, or abdominal pain may find it helpful to reduce the dose temporarily. Talk to your doctor to see if this may be an option for you if you have side effects.
If you are taking other medications or supplements that contain iron, aluminum, or zinc, leave at least 4 hours between taking deferiprone and the other medication.
If you are using deferiprone liquid, use an oral syringe to measure each dose of the liquid, as it gives a more accurate measurement than household teaspoons.
Many things can affect the dose of medication that a person needs, such as body weight, other medical conditions, and other medications. If your doctor has recommended a dose different from the ones listed here, do not change the way that you are taking the medication without consulting your doctor.
It is important to take this medication exactly as prescribed by your doctor.
If you miss a dose, take it as soon as possible and continue with your regular schedule. If it is almost time for your next dose, skip the missed dose and continue with your regular dosing schedule. Do not take a double dose to make up for a missed one. If you are not sure what to do after missing a dose, contact your doctor or pharmacist for advice.

Are there any other precautions or warnings for this medication?
Before you begin using a medication, be sure to inform your doctor of any medical conditions or allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use this medication.
Infection: Deferiprone can reduce the number of cells that fight infection in the body (white blood cells). If possible, avoid contact with people with contagious infections. Tell your doctor immediately if you notice signs of an infection, such as fever or chills, severe diarrhea, shortness of breath, prolonged dizziness, headache, stiff neck, weight loss, or listlessness. Your doctor will do blood tests regularly to monitor the number of specific types of blood cells in your blood.
Liver function: Deferiprone may have an effect on your liver function, causing abnormal liver test results. Your doctor may want to test your liver function regularly with blood tests while you are taking this medication. Usually, this means that reduced liver function can be identified before it becomes too severe. This is particularly important if you have liver problems, such as hepatitis C.
Neurological problems: Deferiprone may cause symptoms related to the nervous system. Vision changes, abnormal movements, and loss of muscle tone have been reported in children taking this medication. If you observe any unusual symptoms, talk to your doctor as soon as possible.
Pregnancy: This medication may cause harm to the developing baby if it is taken by the mother during pregnancy. If you become pregnant while taking this medication, contact your doctor immediately.
Breast-feeding: It is not known if deferiprone passes into breast milk. If you are a breast-feeding mother and are taking this medication, it may affect your baby. Breast-feeding is not recommended if you are taking this medication.
