Pepto Bismol is an over-the-counter medication frequently used for the management of intermittent symptoms of uncomplicated gastrointestinal problems, including indigestion, heartburn, and diarrhea. 

Pepto-Bismol functions as an antacid to decrease excessive stomach acid and thereby alleviate discomfort. Additionally, it serves to safeguard the stomach and esophagus from the effects of stomach acid.
