Clinical monograph

How it works

It provides ferric iron complexed with maltol, which dissociates to allow iron absorption from the gut for incorporation into haemoglobin and iron stores.

Prescribing in practice

As with all iron, store securely out of reach of children because overdose is a serious poisoning risk.
Avoid during a flare of inflammatory bowel disease and in patients with iron overload disorders.
Separate administration from antacids and certain other medicines that impair iron absorption.

Monitoring

Check haemoglobin and iron indices periodically to confirm response and guide duration of treatment.

Counselling the patient

It may cause abdominal discomfort, wind, constipation or diarrhoea, and can darken the stools.
Take as directed and keep out of the reach of children.
Continue treatment for the recommended period to restore iron stores.

Evidence & guidelines

Oral ferric maltol provides an alternative oral iron option, with use supported by NICE in iron-deficiency anaemia where conventional oral salts are unsuitable.
