Hi.... I understand your concern. Anaemia is a very simple problem, but at the same time, if it is only isolated anaemia the most common reason is Iron deficiency. As a physician has recently checked your son and told that it is only an isolated anaemia and he is also symptomatic - like easy fatigability, I suggest you use iron supplements at 3 mg per kg per day in 1 of 2 divided doses. But this is a prescription drug and this is the reason why I am unable to give you a prescription here. I suggest that you get back to your son s pediatrician regarding this. He will be requiring iron supplements for 3 months consistently. Regards - Dr. Sumanth
