From the Guidelines
The treatment for a patient with low Total Iron Binding Capacity (TIBC) due to iron overload primarily involves therapeutic phlebotomy to remove excess iron from the body, with a target ferritin level of 50-100 lg/L 1. The goal of treatment is to reduce iron stores and prevent organ damage.
- Phlebotomy is typically performed weekly, with the removal of 1 unit of blood (approximately 200-250 mg of iron) as tolerated.
- The choice of treatment depends on the severity of iron overload, patient age, organ involvement, and comorbidities.
- Regular monitoring of serum ferritin levels, liver and cardiac function, and renal function is necessary to adjust treatment as needed.
- Dietary modifications to reduce iron intake are not necessary, but vitamin C supplements and iron supplements should be avoided 1.
- Maintenance phlebotomy may be required to prevent reaccumulation of iron, with the frequency varying among individuals depending on the rate of iron accumulation 1.
From the FDA Drug Label
In patients with iron overload, deferoxamine mesylate is used to reduce iron stores 2. The recommended dose of Desferal in adults is 40 mg/kg/day to 50 mg/kg/day over 8 hours to 12 hours at a rate of up to 15 mg/kg/hour for 5 days to 7 days per week 2. Vitamin C in doses up to 200 mg for adults may be given in divided doses, starting after an initial month of regular treatment with deferoxamine mesylate 2.

Additionally, vitamin C may be given in doses up to 200 mg for adults, starting after an initial month of regular treatment with deferoxamine mesylate, to increase the availability of iron for chelation 2.
From the Research
Low TIBC and Treatment
- Low Total Iron Binding Capacity (TIBC) is often associated with iron overload, which can lead to various health complications.
- Treatment for iron overload typically involves iron chelation therapy, which aims to reduce iron levels in the body and prevent tissue damage 3, 4, 5.
- There are several iron chelators available, including deferoxamine, deferiprone, and deferasirox, which have been shown to be effective in reducing iron levels and improving outcomes in patients with iron overload 3, 4, 5.
- The choice of chelator and treatment regimen depends on various factors, including the severity of iron overload, patient compliance, and potential side effects 4, 6.
- In patients with low TIBC due to iron overload, treatment with iron chelation therapy may help improve TIBC levels and reduce the risk of complications associated with iron overload 7.
- Regular monitoring of iron levels, liver function, and other clinical parameters is essential to assess the response to treatment and adjust the treatment regimen as needed 6.
Iron Chelation Therapy
- Iron chelation therapy is a crucial treatment approach for patients with iron overload, and it has been shown to improve survival and reduce the risk of complications 3, 4, 5.
- The goal of iron chelation therapy is to reduce iron levels in the body and prevent tissue damage, while minimizing the risk of side effects and ensuring patient compliance 4, 6.
- The choice of iron chelator and treatment regimen should be individualized based on patient-specific factors, including the severity of iron overload, medical history, and potential side effects 4, 6.
Clinical Outcomes
- Low TIBC levels have been associated with poor clinical outcomes, including increased mortality, in patients with iron overload 7.
- Treatment with iron chelation therapy has been shown to improve clinical outcomes, including survival, in patients with iron overload 3, 4, 5.
- Regular monitoring of clinical parameters, including iron levels, liver function, and quality of life, is essential to assess the response to treatment and adjust the treatment regimen as needed 6.
