404 adverse event reports received by FDA list deferiprone, a generic name as a suspect or interacting product, from April 2008 to June 2026. A further 118 reports list it only as a concomitant medication, and those are not counted in the figures on this page.

In the 12 months to June 2026, 37 reports listed it, down 21% from 47 in the 12 months before. FDA releases FAERS data quarterly, so the newest months are incomplete and grow in later releases. Over its reporting history that is about 22 reports a year and 0% of the 20,646,523 reports in the database, and 1.5% of the reports for the iron chelator class. How many people take it is not in the data, so a count is not a rate of occurrence.

Reporters most often recorded off label use (21.8%), death (11.4%) and treatment noncompliance (5.7%). A report can list several reactions, so shares add to more than 100%; 142 different terms appear across these reports. Off label use is recorded in 21.8% of these reports, a larger share than in the median iron chelator drug (2.3%).

94.8% of the reports are marked serious by the reporter (85.9% across the class); 19.6% record death among the outcomes and 47.5% record hospitalisation, as reported. 28.5% of the reports came from pharmacists, and the largest patient age group is 18 to 44 (29.7%). FDA states that "a causal relationship cannot be established between product and reactions listed in a report" and that for any given report "there is no certainty that a suspected drug caused the event."

Top 30 of 142 MedDRA preferred terms recorded across these reports, with a plain-language gloss where one is available. One report can record several terms. The hollow bar is the median share across the 5 drugs in the iron chelator class; it describes the reports, not the patients. FDA states that adverse event reports "represent a small percentage of total usage numbers of a product", that "common products may have a higher number of adverse events due to the higher total number of people using the product", and that the data "by themselves are not an indicator of the safety profile of the drug or biologic."

Outcome flags as the reporter set them; a report can carry several, and "other serious" is FDA's own category for serious reports outside the named outcomes. Grey bar: all 26,165 reports in the class. FDA has not verified any outcome and states that the reports "cannot be used to estimate the incidence of these events."

Shares are of reports, not of patients treated. The number of people taking a product is not in the data, so none of these figures is a rate, and differences between columns reflect who takes a product, who reports and how long it has been sold. FDA states that adverse event reports "represent a small percentage of total usage numbers of a product", that "common products may have a higher number of adverse events due to the higher total number of people using the product", and that the data "by themselves are not an indicator of the safety profile of the drug or biologic."

Ordered by report count for navigation only. FDA states that adverse event reports "represent a small percentage of total usage numbers of a product", that "common products may have a higher number of adverse events due to the higher total number of people using the product", and that the data "by themselves are not an indicator of the safety profile of the drug or biologic." A brand and its generic are separate rows because reporters name them separately.

Questions about Deferiprone reports

How many adverse event reports has FDA received for Deferiprone?

404 reports list Deferiprone as a suspect or interacting product in the openFDA FAERS release of 28 Sep 2026, covering reports received through June 2026. 37 of them arrived in the latest 12 months. Another 118 list it only as a concomitant medication.

What reactions are recorded in Deferiprone reports?

off label use (21.8%), death (11.4%), treatment noncompliance (5.7%), agranulocytosis (5.4%) and ill-defined disorder (4.7%). These are MedDRA preferred terms coded from what the reporter described; a report can list several, and a term's presence is not a finding that Deferiprone was responsible.

How serious are the reports?

94.8% are marked serious by the reporter. Among the outcomes recorded, 19.6% of reports include death and 47.5% include hospitalisation. FDA has not verified these outcomes and states that the reports "cannot be used to estimate the incidence" of the events.

Who files these reports?

pharmacist (28.5%), other health professional (26.5%) and consumer or non-health professional (22.3%). Most reports reach FDA through the manufacturer, which must forward reports it receives.

Are reports for Deferiprone rising?

37 reports in the 12 months to June 2026, down 21% from 47 in the 12 months before. FDA releases FAERS data quarterly, so the newest months are incomplete and grow in later releases. Counts also move with how many people take a product, its time on the market and publicity.

Do these reports show that Deferiprone was responsible for these reactions?

No. FDA states that "a causal relationship cannot be established between product and reactions listed in a report" and that for any given report "there is no certainty that a suspected drug caused the event." The reaction may relate to the condition being treated, to other medicines, or to something else.

Is this a list of the side effects of Deferiprone?

No. It is a count of what was reported to FDA. The adverse reactions observed in clinical studies are printed on the FDA-approved label, which a pharmacist or clinician can go through with you.

How do I report an adverse event?

Consumers and health professionals can report to FDA through MedWatch (Form FDA 3500 online, or 1-800-FDA-1088), or to the manufacturer, which must pass reports on. See the guide on how to report.

Where this comes from. Counts are built from the openFDA Drug Adverse Event (FAERS) bulk export released 28 Sep 2026, which holds reports FDA received through 30 Jun 2026. Drug names are as reported, resolved to the brand or generic name on the FDA label where openFDA's harmonisation matched them; classes are the pharmacologic class (EPC) from the label and the National Drug Code Directory of 17 Sep 2026. A report counts here when it lists Deferiprone as a suspect or interacting product; reports listing it only as a concomitant medication (118) are excluded. No report narrative, lot number, patient detail or reporter identity is published. See the methodology and sources; FDA's record is authoritative, and corrections are handled within five working days.
