It is first reduced to leucomethylene blue, which reduces heme group from methemoglobin to hemoglobin. It is given in a dose of 1 mg/kg IV over 5-30 minutes. If methemoglobin level remains greater than 30%, a repeat dose can be given after one hour. Along with dihydroartemisinin-piperaquine, methylene blue in an oral dose of 15 mg/kg/d for 3 days, is useful to treat artemesinin-resistant malaria and
