The usual dose is 180 mg per day of Iron in adults and 2 mg per kg of body weight per day in children.
Usually ferrous sulfate, 325 mg, three times per day is given, which yields 180 mg of Iron (about 10-20 mg is
absorbed).
Symptoms of Iron deficiency anemia include easy fatigability, tachycardia, palpitations and tachypnea on exertion.
Blood tests must be monitored during Iron supplementation at these high doses to ensure adequate replenishment
and the prevention of Iron overload. It may take one to two months to correct anemia with further supplementation
to replenish Iron stores.8
