Sodium bicarbonate tablets are baking soda tablets mainly used for the treatment of stomach acid, acid reflux, heartburn and other gastrointestinal disorders. During gastric disorders, if there is no ulcer or erosion of the gastric mucosa, you can use soda tablets or baking soda tablets to relieve the symptoms of stomach acidity. However, if there is a peptic ulcer or erosion of the gastric mucosa, remember not to use sodium bicarbonate tablets or sodium carbonate tablets because the combination of this drug with gastric acid will produce a large amount of carbon dioxide gas, resulting in a large amount of gas accumulation in the stomach and weakness of the mucosa and muscle layer at the erosion or ulcer, which can easily perforate and cause more damage. Perforation of the gastrointestinal tract can cause various infections secondary to high fever, abdominal pain, nausea, vomiting and even infectious shock. During the medication period, pay attention to the regular diet, avoid spicy, stimulating and cold food, pay attention to rest, and stop the medication immediately if there are uncomfortable symptoms.
