FERRIPROX SIDE EFFECTS
- Generic Name: deferiprone
- Brand Name: Ferriprox

The following clinically significant adverse reactions are described below and elsewhere in the labeling:
- Agranulocytosis and Neutropenia
- Liver Enzyme Elevations
- Zinc Deficiency
Clinical Trial Experience
Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.
FERRIPROX tablets (twice a day) were evaluated in trials in healthy subjects. Currently, there are no clinical data in patients with FERRIPROX tablets (twice a day). FERRIPROX tablets (twice a day) contain deferiprone, the same active ingredient as FERRIPROX (deferiprone) tablets (three times a day) and oral solution. The following adverse reaction information represents the pooled data collected from 642 patients who participated in single arm or active-controlled clinical trials taking FERRIPROX (deferiprone) tablets (three times a day) and oral solution.
The most serious adverse reaction reported in clinical trials with FERRIPROX was agranulocytosis.
The table below lists the adverse drug reactions that occurred in at least 1% of patients treated with FERRIPROX in clinical trials.
Table 1:Adverse drug reactions occurring in ≥ 1% of FERRIPROX-treated patients
|BLOOD AND LYMPHATIC SYSTEM DISORDERS|
|Alanine Aminotransferase increased||7|
|Aspartate Aminotransferase increased||1|
|METABOLISM AND NUTRITION DISORDERS|
|MUSCULOSKELETAL AND CONNECTIVE TISSUE DISORDERS|
|Pain in extremity||2|
|NERVOUS SYSTEM DISORDERS|
Gastrointestinal symptoms such as nausea, vomiting, and abdominal pain were the most frequent adverse reactions reported by patients participating in clinical trials and led to the discontinuation of FERRIPROX therapy in 1.6% of patients.
Chromaturia (reddish/brown discoloration of the urine) is a result of the excretion of iron in the urine.
The following additional adverse reactions have been reported in patients receiving FERRIPROX. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or to establish a causal relationship to drug exposure.
