sodium feredetate trihydrate: clinical details
Prescribing considerations
- Confirm iron deficiency and assess its underlying cause rather than treating unexplained anaemia empirically.
- Review prescribed medicines, supplements and diet for clinically relevant absorption interactions.
- Black stools are expected with oral iron and can interfere with faecal occult-blood testing.
- Consider the sorbitol, ethanol, sodium, parabens and colourant content when clinically relevant.
Contraindications and cautions
- Hypersensitivity to sodium feredetate trihydrate or an excipient
- Haemochromatosis or haemosiderosis
- Repeated blood transfusions
- Concurrent parenteral iron therapy
- Hereditary fructose intolerance because the oral solution contains sorbitol
Monitoring
- Monitor haemoglobin and appropriate iron indices to confirm response and avoid unnecessary iron exposure.
- Investigate inadequate response, recurrent deficiency or unexpected intolerance.
- Watch for toxic accumulation during prolonged or excessive use in children.
Clinical pharmacology
Sodium feredetate contains non-ionised iron chelated with sodium EDTA. Gastrointestinal dissociation releases elemental iron for haemoglobin synthesis and storage; absorption increases in iron-deficient states. EDTA is poorly absorbed and is eliminated largely unchanged.
Formulation and product differences
- The selected formulation is a red, cherry-flavoured oral solution.
- The chelated formulation is not astringent and is not expected to discolour teeth.
- Water is the recommended diluent when dilution is required.
- The solution contains sorbitol and excipients capable of causing gastrointestinal discomfort or allergic reactions.
sodium feredetate trihydrate interactions
Oral iron can bind other medicines or have its own absorption altered. A pharmacist or prescriber may need to adjust how interacting products are taken.
Dimercaprol
Avoid combination because potentially toxic compounds may form.
Tetracycline and fluoroquinolone antibiotics
Iron can reduce antibiotic absorption; tetracyclines also reduce iron absorption.
Levothyroxine
Iron can reduce levothyroxine absorption and compromise thyroid treatment.
Mycophenolate, penicillamine and bisphosphonates
Iron can reduce absorption of these medicines.
