Continue for 3-6 months after the Hb reaches normal to replenish iron stores.
Hb is expected to rise by at least 1.5 g/dL in two weeks.
If Hb does not increase after two weeks, do a full blood count (FBC) to confirm hypochromic microcytic anaemia.
When using iron together with calcium supplementation, ensure that iron and calcium are taken at least 4 hours apart from one another.
If there is no response to oral iron, review adherence and do a FBC. If iron deficiency is confirmed on FBC and oral iron is not tolerated consider intravenous iron sucrose using the following formula:
Total dose = weight (kg) x [11 g/dL - actual Hb (g/dL)] x 2.4 + 200 mg. Maximum daily dose: 200 mg. Administer over 30 minutes in 200 mL sodium chloride 0.9%. Repeat every second day until the total dose is given.
If delivery is anticipated within 3-5 days, consider blood transfusion in women with a Hb <7 g/dL.
