Yes: Pepto bismol (bismuth subsalicylate) is used for nausea, heartburn, indigestion, upset stomach and diarrhea. Since heartburn is a common signs of acid reflux, most likely pepto bismol (bismuth subsalicylate) will help. Consult your doctor about a medication you can take if this over the counter drug does not help. Always consult your doctor about mixing medications as well since I am not familiar with your medical history.
