NTAG Sept 2018: ​The Northern (NHS) Treatment Advisory Group recommends the use of oral Ferric Maltol as an alternative option in adult patients with mild to moderate iron deficiency anaemia who have been unable to tolerate at least two oral ferrous salts due to adverse effects after an adequate trial (e.g. 3 months) and who would otherwise be treated with IV iron. The recommendation to prescribe Ferric Maltol should be made by a secondary care specialist experienced in the management of IDA.
