When Should Antacids Be Taken?

Antacids should be used when you have symptoms or think you will get them soon – for most people, the best time to take them is with or soon after meals, and just before going to bed. Remember that doses for children may be lower than for adults.

Should antacids be taken on an empty stomach?

Take antacids about 1 hour after eating or when you have heartburn. If you are taking them for symptoms at night, do not take them with food. Antacids cannot treat more serious problems, such as appendicitis, a stomach ulcer, gallstones, or bowel problems.

Why are antacids taken after meals?

Medicines called antacids are taken to prevent heartburn and acid reflux and indigestion, which usually occur when acid is produced as food enters your stomach. Therefore, these medicines are most effective if taken immediately after, or during, a meal.
