What is True about oral iron supplements used for iron deficiency anaemia and explain in detail?
Tolerable dose of elemental iron is 200 mg per day in three divided doses i.e. app. 60 mg per dose.

Mass of elemental iron is more important in determining daily dose rather than a mass of total salt, because different salts provide a different amount of elemental iron.
Treatment with oral iron should be continued even after reaching the desired haemoglobin level to replenish the stores.
The desired rate of haemoglobin improvement is 0.5 to 1 mg per week (not day).
