Deferiprone, sold under the brand name Ferriprox among others, is a medication that chelates iron and is used to treat iron overload in thalassaemia major.[5] It was first approved and indicated for use in treating thalassaemia major in 1994[6] and had been licensed for use in the European Union for many years while awaiting approval in Canada and in the United States.[5] On 14 October 2011, it was approved for use in the US under the FDA's accelerated approval program.[7][8]

The most common side effects include red-brown urine (showing that iron is being removed through the urine), nausea (feeling sick), abdominal pain (stomach ache) and vomiting.[9][7] Less common but more serious side effects are agranulocytosis (very low levels of granulocytes, a type of white blood cell) and neutropenia (low levels of neutrophils, a type of white blood cell that fights infections).[9][7]
