Over-the-counter (OTC) digestive medications alleviate common digestive issues like indigestion, heartburn, acid reflux, bloating, gas, and diarrhea. They include antacids, acid reducers, PPIs, and anti-diarrheal agents. Antacids neutralize stomach acid, while acid reducers and PPIs reduce acid production. Anti-diarrheal agents relieve diarrhea. OTC digestive meds provide temporary relief for mild discomfort. Follow instructions and consult a healthcare professional if symptoms persist.
