A low white blood cell count is one of the side effects known to occur is some users of deferiprone (Ferriprox, Kelfer). Neutropenia can occur and depending on how low the white cell count has dropped, either a temporary reduction in dosage or temporary cessation altogether is recommended when this occurs. Once the white cell count is normalized, the drug can be started again. When a severe drop occurs, agranulocytosis, the drug should be stopped altogether. Not enough information is available to recommend re-challenging a patient with deferiprone once agranulocytosis. has taken place, and another chelator should be used.
Your white cell count is lower than normal, but not dangerously so. Either a temporary cessation or at least a reduction in daily dose should be taken until the level restores. This is a common side effect of deferiprone, but when managed properly, the drug can be continued as long as the white cell level is restored.
