- Patients diagnosed with clinically significant IDA should have iron replacement therapy to correct anaemia and replenish iron stores.
- Treatment should normally be conducted in parallel with investigations to determine the underlying cause. However, for some patients such as those with complex multi-morbidity or approaching end of life, such investigations may not be appropriate.
- Oral iron is the first line treatment of choice*.
- Prescribe ferrous fumarate 210mg or ferrous sulfate 200mg once a day as initial therapy (see below for information on dosing).
- Oral iron therapy should be continued for 3 months after haemoglobin (Hb) optimised and then stopped (consider ongoing prophylaxis in at risk patients).
- The irritant adverse effects of oral iron are related to the amount of elemental iron taken rather than the type of preparation.
- Iron preparations with a low content of elemental iron must be tried (with food) before acceptance of genuine intolerance to oral iron.
* see inclusion criteria for IV iron therapy in full guideline, including use as first line agent in certain clinical settings.
