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
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
