How long is typically required to replete iron stores with oral therapy?

12-24 months 6-12 months 3-6 months 1-2 months

Correct Answer:

3-6 months

Explanation:

Replenishing iron stores with oral therapy takes months, not just weeks. While hemoglobin often begins to rise quickly once therapy starts, the body’s iron reserves (ferritin stores) require a longer, steady input of iron to be rebuilt. With standard oral iron, the usual course is enough to restore depleted stores over several months—typically around half a year. The exact duration depends on ongoing blood loss, absorption, dosage, and adherence. You monitor progress by checking ferritin and iron indices, continuing therapy until stores are replenished even after hemoglobin has normalized. Shorter courses may raise Hb but leave stores depleted, while longer courses are needed if losses persist or absorption is poor.
