 There is no consensus on how to treat LID but one of the options is to treat it as an iron-deficiency anemia with ferrous sulfate (Iron(II) sulfate) at a dose of 100 mg x day in two doses (one at breakfast and the other at dinner) or 3 mg x Kg x day in children (also in two doses) during two or three months.The ideal would be to increase the deposits of body iron, measured as levels of ferritin in serum, trying to achieve a ferritin value between 30 and 100 ng/mL.Another clinical study has shown an increase of ferritin levels in those taking iron compared with others receiving a placebo from persons with LID.
