How to Properly Dissolve and Take Sodium Bicarbonate Tablets
Dissolve sodium bicarbonate tablets completely in a full glass of water before drinking—never swallow them whole or take them when partially dissolved, as this can cause serious gastrointestinal injury. 1
Critical Safety Instructions

Special Populations
Clinical Context
The FDA labeling prioritizes oral sodium bicarbonate for antacid use, where complete dissolution prevents direct contact injury to the esophagus and stomach mucosa. The emphasis on avoiding use when "overly full" relates to preventing gastric distension and potential perforation risk from gas production during tablet dissolution 1.
While the medical literature discusses sodium bicarbonate for various clinical indications (metabolic acidosis, cardiac arrest, toxicology), these applications use different formulations and routes (typically intravenous hypertonic solutions) 2, 3. The oral tablet formulation described here is specifically designed for antacid use with the safety parameters outlined above.
