Yikes! So how can one take antacid and be secure?
A. It’s best to save antacid for a few hours after eating when the food will have spent that amount of time in the acid bath. If your need for antacid is more urgent, a brand called Gaviscon might be of assistance. It’s not really an antacid. It forms a kind of liquid dam that floats on top inside your stomach to keep stomach juices out of the esophagus. That way your esophagus is protected without impairing the stomach’s natural defenses. Gaviscon won’t really neutralize the acid though, so you might need real antacid later, but by that time, your stomach will be nearly empty.
