When using antacids, how long should iron tablets be separated?

The correct choice indicates that iron tablets should be separated from antacids by 2 hours. This is because antacids can interfere with the absorption of iron in the gastrointestinal tract. When both are taken close together, the antacid can bind to iron, preventing the body from absorbing it effectively. A separation of 2 hours helps to ensure that the gastrointestinal system can properly absorb the iron before the antacid is introduced, optimizing the effectiveness of the iron supplementation.

It's important for individuals who are taking iron supplements, especially pregnant women or those with specific iron needs, to manage their medication schedule carefully to enhance the absorption of iron.
