How effective and safe are pepto-bismol and tums (calcium carbonate)? How do they work?

1 doctor answer
Dr. Ronald Kline
Specializes in Colon and Rectal Surgery
Fairly safe: Both are reasonably safe for short term use. However, long term use can lead to problems. Both work primarily by coating the stomach to help acid effects. With prolonged use the normal bacteria in the GI tract can be depleted and abnormal bacteria can overgrow. Alos prolonged use of peptobismol can cause discoloration of the intestinal tract along with elevated levels of bismuth.
