how long does it take for pepto-bismol to work

Pepto-Bismol usually takes about 30 to 60 minutes to start working and provide relief from symptoms such as nausea, heartburn, indigestion, upset stomach, and diarrhea. Mild symptoms typically respond within 30 minutes, but severe digestive distress may require up to 4 hours for noticeable improvement. If symptoms persist, another dose can be taken after 30 to 60 minutes, but no more than 8 doses should be taken in a 24-hour period. It is important to follow the dosing instructions and consult a doctor if symptoms persist beyond 2 days.
