The absorption of
iron and the expected haematological response can be reduced by the concurrent use of
antacids (sodium bicarbonate,
calcium carbonate, alum- inium/magnesium hydroxide, magnesium trisilicate).
Separate the
administration of
iron preparations and
antacids as much as possible to avoid admixture in the gut. Note that separating the dosing by 2 to 3 hours minimises other absorption interactions with
antacids.
