How Antacids Work

Want instant relief from heartburn? Here are some tips on how to get it.

If you are suffering from heartburn now, you may find instant with an over-the-counter antacid like Tums or Rolaids. Antacids work by neutralizing acid in the stomach, so that when the acid enters the esophagus, it will be weaker and therefore, less painful. Antacids work rapidly but they do not last for long. If you need to take antacids more than several times a month or do not experience relief using them, your doctor may recommend you to try a different medication such as Histamine-2 or H2 blockers.

H2 blockers like Zantac and Axid lasts longer than antacids but they also take longer to absorb into the body. Sometimes an hour is needed to feel the effects. For this reason, you may want to try an OTC medication that combines an antacid and an H2 blocker, so you get the quick onset of action combined with sustained relief.
