From the Guidelines
No, sodium bicarbonate is not the same as Tums, as they contain different active ingredients and have distinct chemical properties. Sodium bicarbonate, also known as baking soda, is a chemical compound with the formula NaHCO3, whereas Tums primarily contains calcium carbonate (CaCO3) or famotidine, an H2 blocker. The provided evidence does not directly compare sodium bicarbonate and Tums, but it discusses the use of antacids and acid reducers in various clinical contexts 1.
Key Differences
- Sodium bicarbonate reacts with stomach acid to produce salt, water, and carbon dioxide, while calcium carbonate reacts to form calcium chloride, water, and carbon dioxide.
- Famotidine, the active ingredient in some Tums products, works by reducing acid production in the stomach.
- The choice of antacid or acid reducer depends on the individual's specific needs and health conditions, and it is essential to consult with a healthcare provider before using any of these medications, especially if you have underlying health conditions or are taking other medications.
Clinical Considerations
- The evidence suggests that sodium bicarbonate may be beneficial in treating certain conditions, such as chronic low-grade metabolic acidosis, by increasing plasma bicarbonate levels and reducing net endogenous acid production 1.
- Famotidine, on the other hand, has been shown to be effective in reducing the incidence of peptic ulcers and erosive esophagitis in patients taking low-dose aspirin 1.
- However, the use of proton pump inhibitors (PPIs) and other acid reducers may be associated with potential interactions with other medications, such as clopidogrel, and should be used with caution 1.
Recommendation
In conclusion, sodium bicarbonate and Tums are not interchangeable, and the choice of antacid or acid reducer should be based on individual needs and health conditions, with consideration of potential interactions with other medications. Always consult with a healthcare provider before using any antacid or acid reducer, especially if you have underlying health conditions or are taking other medications 1.

From the Research
Comparison of Sodium Bicarbonate and Tums (Famotidine)
- Sodium bicarbonate and Tums (famotidine) are not the same, as they have different active ingredients and mechanisms of action 2, 3.
- Tums is a brand of antacid that typically contains calcium carbonate, which is used to neutralize stomach acid and relieve heartburn symptoms 4, 3.
- Sodium bicarbonate, on the other hand, is a type of antacid that can help neutralize stomach acid, but it is not the same as calcium carbonate 2, 5.
- Famotidine, the active ingredient in Pepcid AC, is a histamine-2 (H2) blocker that reduces acid production in the stomach, whereas sodium bicarbonate and calcium carbonate work by neutralizing existing acid 3.
Mechanism of Action
- Sodium bicarbonate works by neutralizing stomach acid and increasing gastric pH, which can help relieve heartburn and indigestion symptoms 2, 5.
- Calcium carbonate, the active ingredient in Tums, also works by neutralizing stomach acid, but it can cause an "acid rebound" effect, where the stomach produces more acid to compensate for the neutralization 4.
- Famotidine, on the other hand, works by reducing acid production in the stomach, which can provide longer-lasting relief from heartburn and acid reflux symptoms 3.
Clinical Use
- Sodium bicarbonate and Tums (calcium carbonate) are often used to relieve mild heartburn and indigestion symptoms, while famotidine is used to treat more severe heartburn and acid reflux symptoms 2, 4, 3.
- Alginate-based raft-forming formulations, such as Gaviscon, can also be used to treat heartburn and acid reflux symptoms, and they work by forming a physical barrier on top of the stomach contents to prevent acid reflux 6.
