From the Guidelines
For an iron deficit of 1220mg, oral iron supplementation is the preferred treatment option, rather than transfusion, as it is safer, less expensive, and allows for gradual correction of the deficit. According to the British Society of Gastroenterology guidelines for the management of iron deficiency anaemia in adults 1, oral iron therapy is recommended as the first-line treatment for iron deficiency anaemia, with a suggested dose of 50-100mg of elemental iron per day.
The guidelines suggest that a once daily dose of 50-100mg of elemental iron, such as ferrous sulfate 200mg tablet, taken in the fasting state, may be the best compromise option for initial treatment 1. It is essential to monitor the initial haematological response and modify the treatment as appropriate in case of apparent therapeutic failure.
Transfusion is generally reserved for patients with severe anemia causing hemodynamic instability, significant symptoms, or those who cannot tolerate oral therapy 1. The guidelines recommend considering restricted packed cell transfusion for moderately severe anaemia, but also emphasize the importance of commencing oral iron replacement therapy (IRT) once daily with 50-100mg elemental iron 1.
It is crucial to continue oral iron supplementation for 3-6 months to fully replenish iron stores, and to monitor hemoglobin and ferritin levels after 4-8 weeks of therapy to assess response 1. Patients should be advised to take iron supplements on an empty stomach and avoid taking them with calcium, dairy products, tea, coffee, or antacids, which can reduce absorption.
If oral iron is not tolerated or ineffective after 1-2 months, consider intravenous iron formulations, and in patients with chronic disease, continuing blood loss, impaired absorption, or GI inflammatory pathology, parenteral iron may be more effective than continuing traditional oral therapy 1.
Key points to consider when treating iron deficiency anaemia include:
- Oral iron supplementation is the preferred treatment option
- Transfusion is reserved for severe cases
- Monitor haematological response and adjust treatment as needed
- Continue oral iron for 3-6 months to replenish iron stores
- Avoid taking iron supplements with substances that reduce absorption.

From the Research
Iron Deficiency Treatment
The treatment for iron deficiency typically involves oral iron supplementation as the first line of treatment 2. This can include ferrous sulfate, other ferrous salts, and ferric complexes.
Oral Iron Supplementation
- Oral iron supplementation is usually efficacious in correcting iron-deficiency anemia and replenishing iron stores 2.
- However, it can cause gastrointestinal side effects that reduce compliance 2.
- Emerging data suggest that low-dose iron has comparable efficacy, with fewer side effects 3.
- A low starting dose of oral iron, such as one ferrous sulfate tablet per day, for treatment of iron deficiency is worth considering 3.
Intravenous Iron Therapy
- Intravenous iron therapy can rapidly achieve therapeutic targets without gastrointestinal complications when oral iron supplementation is contraindicated 2.
- Both intravenous and oral iron can effectively raise hemoglobin levels in iron-deficiency anemia, with no evidence that intravenous iron can raise hemoglobin at a faster pace 3.
Specific Case
For an iron deficit of 1220mg, the decision to transfuse or give oral iron depends on various factors, including the severity of the deficiency, the presence of any underlying medical conditions, and the patient's overall health. However, based on the available evidence, oral iron supplementation is usually the first line of treatment for iron deficiency 2, 3.
