Chronic iron overload in beta-thalassemia patients after continuous blood transfusions has caused notable morbidity and mortality in these patients. The once-a-day oral iron chelator, deferasirox has established efficacy and bearable safety in adults and pediatric thalassemia patients. It is now extensively used for the management of transfusional hemosiderosis. However, a number of studies have revealed a few patients continued to be none respondent or intolerant toward the once-a-day regimen of deferasirox even after the administration of maximum dose recommended by the World Health Organization. In the literature, there were three studies showing the boon of twice in a day dosing of deferasirox among transfusional-dependent beta thalassemia patients. Therefore, a nonsystematic review was conducted on above three studies to ascertain the enhanced effectiveness and tolerability of twice per day regimen of deferasirox with the same total dose as that of once daily regimen of deferasirox in unresponsive or intolerant transfusion-dependent beta-thalassemia (TDT) patients. All the above studies concluded that the twice per day regimen of deferasirox was more efficacious and tolerable among TDT patients when compared to the once-a-day regimen with the same total daily dose. Although there was a significant good results from these studies, there is a need to conduct either muticenter study or randomized control study in a larger number of patients for the better confirmation of the results as all the above studies were conducted in the small number of TDT patients.
